Pesticide Exposure And Women’s Health


When neither the cross-sectional unit nor times have significant effects, all of the data can be pooled and one can have the constant coefficients model. As with most health questions, the answer is related to what farmers tend to do and what they don’t . Studies in Australia, Canada and France also reported lower cancer rates among farmers, which may be related to lifestyle as well. Pesticides must be registered under the PCPA before they can be imported, manufactured, sold or used in Canada. Registration under the PCPA requires a thorough scientific evaluation by the PMRA to determine if new pesticides are acceptable for a specific use and if registered pesticides remain acceptable for use once on the market. If Canadians choose to use pesticides, they can only use a pesticide registered by the federal government for the pests and treatment areas listed on the label, and use them according to the label directions.

This report shows that consumers can choose organic and conventionally grown fruits and vegetables with confidence. It also underscores that no one and no group should discourage consumers from eating healthy produce by promoting unwarranted safety fears about residues. New study links pesticides—including chlorpyrifos, glyphosate, permethrin, and paraquat—to the fatal disease in the US. Remember that pesticides can trigger a range of side effects and that people have varying sensitivities to different chemicals. So the same pesticide can cause severe illness in one person while another person could show no symptoms at all. A number of pesticides including the neonicotinoids clothianidin, dinotefuran, imidacloprid are toxic to bees.

For instance, an IPM farm may grow pest-resistant crop varieties, use predatory insects to kill plant-eating pests, employ mechanical pest traps and eliminate pest nesting areas. It’s important to note that observational and associational research, which observe correlations between factors without performing experiments, are categorized as “weaker evidence” in these types of assessments and don’t get much weight. However, they can still point to concerning connections that aren’t always picked up in lab studies. In Sri Lanka, for example, researchers found a high correlation between glyphosate use, water contamination, and kidney damage.

An October 2012 report by Pesticide Action Network North America entitled “A Generation in Jeopardy” examines dozens of recent studies and concludes that the influx of pesticides in our society is taking a heavy toll on our kids’ health and intelligence. But as the concerns mount, agrichemical industry allies are pushing back. This month a group of three researchers with long-standing close ties to the companies that sell agricultural pesticides released a report seeking to soothe consumer worries and discount the scientific research. Peeling fruits, especially peaches, pears and apples, will help remove residues. Some pesticides permeate the skin of the fruit, so this method does not guarantee residual free produce in all cases.

None of the pesticides that are authorized for use on food in international trade today are genotoxic . Adverse effects from these pesticides occur only above a certain safe level of exposure. When people come into contact with large quantities of pesticide, this may cause acute poisoning or long-term health effects, including cancer and adverse effects on reproduction. Such IPM strategies should aim at reducing the pesticides residues on food products and pesticides-free water and air.

Based on an inventory of the pesticide distribution and health status in all case study areas, SPRINT will evaluate the environmental and economic sustainability impacts for farmers and society of different pesticide use options. The findings of SPRINT will improve the pesticide evaluation process by creating a Global Health Impact Assessment toolbox with aligned tools and methods for an integrated assessment of pesticide exposure, risks and sustainability. In recent years, products with some highly toxic pesticide ingredients have been removed from store shelves.

These insecticides, which include dichlorodiphenyltrichloroethane , have been largely banned or restricted due to negative effects on the environment. Several of them have been banned or restricted due to toxic accidental exposures. This type of pesticide is especially important for protecting harvested crops and seeds from fungal rot. Pesticides are used to reduce damage to crops from weeds, rodents, insects, and germs, which increases the yield of fruits, vegetables, and other crops. Carefully read and follow the instructions on the label for any pesticides you use.

Their Pesticide Section works with commercial and private applicators, pesticide manufacturers and dealers, structural pest control operators, farmers, landscapers and others to ensure regulations are followed for public safety. TDA will accept written requests to investigate the misuse or misapplication of pesticides. While pesticide companies claim their products are needed to feed the world’s growing population, this study’s findings point in the opposite direction. The continued use of toxic chemicals to grow our food undermines the healthy soil ecosystems that sustainable food production depends on.

Pesticides can prevent large crop losses and will therefore continue to play a role in agriculture. However, the effects on humans and the environment of exposure to pesticides are a continuing concern. For example, insecticides tend to be more toxic to humans than herbicides. Many of the older, cheaper (off-patent) pesticides, such as dichlorodiphenyltrichloroethane and lindane, can remain for years in soil and water. These chemicals have been banned by countries who signed the 2001 Stockholm Convention – an international treaty that aims to eliminate or restrict the production and use of persistent organic pollutants.

Although pesticides are directly applied in soils and plants, only 1% of pesticide sprayed is delivered to the intended target. An accidental release of pesticides due to leaking pipes, spills, waste dumps, underground storage tanks, and groundwater may lead to their persistence in the environment for a long time (due to long half-lives). For proper management of pesticides, one needs to accurately assess the status of their contamination in soil, water, and air .

Agronomic Pesticide Update With Core And Cat Pc, 01, 18

Do not use a product labeled for outdoor use, lawns or agricultural use. Studies have shown small to moderate increases in some nutrients in organic produce. The best evidence Cheef Botanicals CBD Gummies of a significant increase is in certain types of flavonoids, which have antioxidant properties. Other common food labels should also not be confused with organic labels.

Acute toxicity is measured as the amount or concentration of a toxicant– the a.i.–required to kill 50 percent of the animals in a test population. Additionally, the LD50 and LC50 values are based on a single dosage and are recorded in milligrams of pesticide per kilogram of body weight (mg/kg) of the test animal or in parts per million . LD50 and LC50 values are useful in comparing the toxicities of different active ingredients and different formulations containing the same active ingredient.

Study Finds Uk Women Living With Abusers More Likely To Catch

The “revolving door,” by which former industry leaders serve in the government agencies overseeing their industries, iswell-usedbyagribusiness, mainly to keep regulation of pesticides and other agricultural products and practices extremely limited. The World Health Organization and an affiliate, the International Agency for Research on Cancer, have classified some pesticides as “probably” or “possibly” carcinogenic. Health Canada is therefore re-evaluating these pesticides to determine if their current conditions of use in Canada pose a threat.

Pesticides banned in the EU account for more than a quarter of all agricultural pesticide use in the USA. The majority of pesticides banned in at least two of these three nations have not appreciably decreased in the USA over the last 25 years and almost all have stayed constant or increased over the last 10 years. Wash and scrub all fresh fruits and vegetables thoroughly under running water, which has an abrasive effect that soaking alone does not. Washing will help remove bacteria and traces of pesticides; however, not all pesticides residues can be removed by washing.

Despite approval by European safety agencies, many European governments have banned the cultivation of GMOs. This seems hypocritical, since Europe imports about 50 million TONS of feed, primarily GMO-based. I believe the NIH recognition of glyohosphate as a carcinogen is something of a motivator, along with the several countries that have banned GMO in favor of what REALLY is traditional agriculture. Perhaps you have been asleep, but there is a huge movement toward small-scale community ag, so I think plenty of folks are motivated. Sure, the mainstream masses may not be just yet, but if we can get biotech and big pharma out of government, we can begin a large scale educational project.

Other Ways To Keep The Cost Of Organic Food Within Your Budget

Developmental impacts were mainly described as behavioral or cognitive, particularly those related to attention-deficit disorders and motor skills . Although the benefits of pesticides have been immense, humans and other living organisms are often exposed to them in the environment . Public health concerns regarding the improper use of pesticides and poison have increased in recent years. To date, certain countries, regions, and international organizations have established maximum residue limits for foodstuffs. Additionally, national food monitoring programs for pesticides have been enacted worldwide [7–9] to ensure consumer health, improve the management of agricultural resources, and prevent economic losses . The industrialization of the agricultural sector has increased the chemical burden on natural ecosystems.

Agents that contribute to ill health in exposed men may also affect exposed women, sometimes in unexpected ways. A total of 5206 samples from twenty one different vegetables and fruits were collected. Residues of pesticides in concentrations exceeding the maximum residue levels were found in 22.9% of analysed samples. Thirteen insecticides, four fungicides, two acaricides and one herbicide were detected in the analysed samples. The obtained results show that the long-term consumption of vegetables and fruits could pose a health risk for the population of the Republic of Moldova. Pesticides are an enormous group of chemicals designed to kill unwanted insects , weeds , rodents , and fungi .


Part of EPA’s assessment of health risks of pesticides is a determination that there is “reasonable certainty of no harm” posed by pesticide residues allowed to remain on food. Before approving a pesticide, EPA sets limits on how the pesticide may be used, how often it may be used, what protective clothing or equipment must be used, and so on. Not only do such alarming claims muddle the food choices the public can safely make, but they also run contrary to the latest advice given by nutritional authorities.

Any harmful effects that occur from small doses repeated over a period of time are termed chronic effects. Some of the suspected chronic effects from exposure to certain pesticides include birth defects, production of tumors, blood disorders, and neurotoxic effects . The chronic toxicity of a pesticide is more difficult to determine through laboratory analysis than acute toxicity. Comparison with other studies conducted in developing countries shows similar results. Pingali et al. showed that 58%–99% of the farmers exposed to pesticides had at least one health effect symptom in Indonesia, Philippines, and Vietnam.

For example, 80-90% of the benomyl residue is removed when apples are made into applesauce and when tomatoes are converted into tomato juice. Pesticides have a broad application, including their use in occupational and nonoccupational settings. Many pesticides have been linked to adverse health effects, and as a result, have been banned from use. The health and environmental risks of inappropriate use of pesticides requires action by all concerned bodies. Improved institutional arrangements for enforcement of regulations, awareness and further intervention studies could lessen the high risks of pesticide misuse. Finally, in Nov 2016, during the waning days of the Obama Administration, the EPA appeared to find enough support for a decision to ban chlorpyrifos, as shown in their revised human health risk assessment.

Some symptoms of pesticide exposure will go away as soon as the exposure stops. For people exposed to pesticides on a regular basis, long-term health effects are a concern. About one percent of the total U.S. fruit and vegetable acreage is organic. In California, about 2% of the state’s farmers are organic farmers, while Texas reports more than 10% of its vegetable-crops are organically grown.

Concern about the environmental impact of repeated pesticide use has prompted research into the environmental fate of these agents, which can emigrate from treated fields to air, other land, and water bodies. The importance of agricultural pesticides for developing countries is undeniable. However, the issue of human health and environmental risks has emerged as a key problem for these countries in accordance to a number of studies. In the last five decades, pesticide usages increased the quantity and improved the quality of food. However, with the increasing amounts of their usage, concern about their adverse effects on nontarget organisms, including human beings, has also grown. The purpose of this publication is to explain the nature of pesticides and their history, classification, risks, and effects on health and the environment.

Acute Effects

Under the optimum conditions, the limit of detection and limit of quantitation were determined to be 9.5 and 32 µg/kg. The relative standard deviations for the lowest concentration in the calibration plot were evaluated to be 7.2%. The proposed method was linear across the working range from 0.05 to 168 mg/kg. Recovery studies were performed to confirm the accuracy and applicability of the developed method.

Simple actions such as maintaining a clean home, taking out the trash, eliminating household sources of moisture and storing food properly can help the situation. These practices should take place in homes and schools to avoid having to use pesticides. The American Academy of Pediatrics policy statement, Pesticide Exposure in Children,and accompanying technical report highlights some of the cbd oil and gummies who sales major health concerns linked to pesticide exposure—particularly prenatal exposure. Pesticide exposure during pregnancy may lead to an increased risk of birth defects, low birth weight, and fetal death. Exposure in childhood has been linked to attention and learning problems, as well as cancer. Pesticides are materials used to control pests such as insects, rodents, weeds, molds and germs.

Organic food is more labor intensive since the farmers do not use synthetic pesticides, chemical fertilizers, or drugs. Organic certification is expensive and organic feed for animals can cost twice as much. Organic farms tend to be smaller than conventional farms, which means fixed costs and overhead must be distributed across smaller produce volumes without government subsidies. Organic farming practices may reduce pollution, conserve water, reduce soil erosion, increase soil fertility, and use less energy. Farming without synthetic pesticides is also better for nearby birds and animals as well as people who live close to farms. In 2018, over 99% of the tested produce contained safe levels of pesticides, and 47.8% had no detectable levels of residue.

When a pesticide drift incident occurs, the chemicals could potentially be inhaled, absorbed by the skin, or land in the eye. Some symptoms include eye, nose, or throat irritation, burning sensation, wheezing, coughing, or rash. The first Paraquat lawsuit was filed in behalf of the farmers and agricultural workers who subsequently developed Parkinson’s disease after being exposed to the chemical in their workplace. The use of pesticides was not as common 10,000 years ago as it is today. Around 1945 “pesticides became common in most areas of the world” (W.R. Carlile). Pesticides are hazardous chemicals that help destroy pest but are putting are environment at risk.

According to USDA data, organic foods have fewer pesticide residues than conventionally grown produce. But the amounts for both types of produce are within the level for safe consumption. And it’s unclear if the pesticides used in organic farming are safer than nonsynthetic pesticides used in conventional farming. Extreme and uncontrolled usage of pesticides produces a number of problems for vegetation and human health.

Can People Become Allergic To Pesticides?

Some people may show no reaction to an exposure that may cause severe illness in others. Because of potential health concerns, pesticide users and handlers must recognize the common signs and symptoms of pesticide poisoning. It’s also important for consumers to make educated decisions about why they choose to buy organic, says Crosby—and not to get hung up on individual studies that haven’t been supported by additional research. If you’re trying to reduce exposure to pesticide residues, organic is a good choice, he says.

These documents are used to determine the probability of adverse effects to humans, wildlife, and the environment from the use of pesticides. Reducing or eliminating pesticide use requires careful ecosystem management, using crop rotations and good soil health practices to build a population of beneficial microorganisms, insects and plants that will do the work of warding off diseases and weeds. Since consumers can’t always see how their food is produced, the EWG’s annual Dirty Dozen and Clean Fifteen lists provide details about what foods have the most and least pesticide residues.

Contrary to what you claim, the world is becoming increasingly urbanized and specialized, with fewer people depending on inefficient subsistence agriculture. I get the sense that you romanticize the peasant lifestyle, but poor farming productivity is a major limitation in the education and equality of girls and women. For those of you who don’t believe that GMO’s are the new solution, I will put this the nicest way as possible. You do realize that so many people were saved because of the less use of pesticides.

Certain active substances tested are highly toxic in an acute setting and can act directly on the nervous system . Pesticides are used to protect crops against insects, weeds, fungi and other pests. The OP insecticides can disturb the function of mitochondria by inducing oxidative stress in central nervous system through critical depletion of mitochondrial energy, the activation of proteolytic enzymes, and DNA fragmentation leading to apoptosis. The dysfunction of mitochondria and oxidative stress is responsible for several neurological diseases, including Parkinson’s disease, seizure, cognitive dysfunction, attention and memory deficits, dementia, depression, and Alzheimer’s disease. OP triggered induction of a xanthine oxidase may play a role in cognitive impairment. Pesticide molecules are small and lipophilic in nature, and can enter from blood to brain and then in neurons, glial cells and brain micro vessels.

Still, fruits and vegetables are highly nutritious and offer many health benefits when enjoyed as part of a balanced diet, regardless of whether they are organic or conventionally grown. Still, while research is mixed on the effects of glyphosate on cancer, the International Agency for Research on Cancer has classified it as a probable human carcinogen . Overall, the potential harm from synthetic and organic biopesticides depends on the specific pesticide and the dose.

The Farmer Who Weeded Out Chemicals

Employers should provide personal protective equipment to workers who have direct contact with pesticides. This includes clothing that prevents pesticides from coming into contact with the skin or being breathed in. This article discusses how pesticides may be harmful to humans, and which fruits and vegetables contain the highest amounts of pesticide residue. Testing produce ensures that levels are low enough to not pose a risk to human health. It’s nearly impossible to avoid all chemicals; they are literally everywhere. The Environmental Working Group website has a lot of valuable information about many different possible exposures and how to decrease them.

It is formulated to provide fast acting results on a long list of weeds and grasses, as well as most mosses and lichens. Cats and dogs are even more vulnerable to most of these disorders than humans, because they have more skin area in proportion to their body size, so they have a proportionally larger surface through which they can absorb poisons. Besides that, they lick their fur and their feet — they never wear shoes. At Community Action Works, we believe that environmental threats are big, but the power of well-organized community groups is bigger.

The occurrence of pesticide mixtures is common in stream waters of the United States, and the impact of multiple compounds on aquatic organisms is not well understood. Watershed Regressions for Pesticides models were developed to predict Pesticide Toxicity Index values in unmonitored streams in the Midwest and are referred to as WARP-… You can learn more about our dedication to relevance, accuracy and transparency by reading our editorial policy.

The regulators echo the words of Monsanto executives and others in the chemical industry by insisting that pesticide residues pose no threat to human health as long as the levels of each type of residue falls under a “tolerance” level set by the EPA. This narrative review refers to studies on human neonicotinoid exposure levels and health effects, and provides an evaluation of the potential toxicity of neonicotinoids on humans. Certified organic coffees are coffees whose growing conditions and processing have been thoroughly monitored by independent agencies and found to be free of pesticides, herbicides, fungicides, chemical fertilizers, and other potentially harmful chemicals. The monitoring agencies visit the farm and verify that no chemicals have been used on the farm for several years, and then follow every step of the processing, preparing, transporting, storage, and roasting.

Preparing, storing, and using homemade pesticides can be dangerous to your health and the environment. They do not have label directions to help you use them safely, and, they may not be effective. The authors would like to acknowledge Jije Laboglass Pvt Ltd, for allowing their laboratory to analyze pesticide residues in Khat samples. The authors gratefully acknowledge the University of Gondar for the funds granted. An Agilent technology 7890B gas chromatograph hyphenated with 5977B Agilent technology mass spectrometer detector with an electron impact ion source at 230°C was used to analyze pesticide residues. A GC column used in the present study was A DB-5MS ultra-inert capillary column (DB-5MS, 30 m × 0.25 mm × 0.25μm).

Allegedly, they are used to protect our homes from structural damage and to increase crop production. In many cases the amount of pesticide to which an individual is exposed is small and does not pose a risk. In other instances either chronic or acute exposure can create serious and lasting health problems. To determine risk, one must consider the toxicity of the pesticide, the likelihood of exposure, the length of exposure, and individual health issues. Insecticides, fungicides, herbicides, rodenticides, and plant growth regulators are typical examples (1–3). These products are also used for other purposes, such as the improvement and maintenance of non-agricultural areas like public urban green areas and sport fields .

Four textures were used for subsurface horizons, which were not coarser in texture than the surface horizon. Organic matter content of a subsurface horizon was 20 percent of the surface horizon. The thirty horizon combinations times four organic matter contents made up 120 soils, summarized in table 1.

Reproductive harm from pesticides includes birth defects, still birth, spontaneous abortion, sterility and infertility. Pests such as vectors (mosquitoes, ticks, fleas, etc.), other insects, rodents and microbes can cause and spread diseases that pose serious risks to public health. Assessment of organophosphorous pesticide exposures in the diets of preschool children in Washington State. Because GMO crops naturally have increased resistance, they require fewer pesticides for successful farming .

In study after study, the first environmental risk factor or probable cause mentioned is pesticides. The FDA found almost 99% of the domestic foods sampled had residues levels well below Environmental Protection Agency safety standards with 42% of foods having no detectable residue levels at all. The Texas A&M AgriLife Extension Service on-line Bookstore offers a number of publications on pesticides – from application and safety issues to agricultural use. Free electronic downloads of these publications (add an “e” in front of the publication number) are also available after setting up an account. Concern about pesticides in ground water is especially acute in agricultural areas, where most pesticides are used, and where more than 95% of the population relies upon ground water for drinking water.

Pesticides enter the food chain through the direct application of the substance to the plants themselves by humans. Once they are absorbed by the plants or animals which eat the plants they become residue. They can also be taken in when an organism takes in the water which contains the runoff and dissolved how long does it take for cbd gummies to work pesticides. An easier way for humans to ingest pesticides is directly through contaminated drinking water from those polluted streams. Pesticides can cause short-term adverse health effects, called acute effects, as well as chronic adverse effects that can occur months or years after exposure.

Registration Review – Through registration review, EPA plans to review all registered pesticides approximately every 15 years to ensure that they meet current scientific and regulatory standards. Reregistration – Under reregistration and tolerance reassessment, EPA reviewed older pesticides to ensure that they meet current scientific and regulatory standards. Collectively, experts (e.g., WHO, Cancer Research U.K., U.S. National Cancer Institute) agree that in addition to aging, the leading Which delta 8 is best for energy? behavioral risk factors for cancer are smoking, alcohol, unhealthy diet, obesity and insufficient physical activity. Infectious agents, such as human papillomavirus and hepatitis B and C viruses, are also important contributors to certain types of cancer. “It continues to build a story about the role of pesticides as a risk factor for ALS.” Texas Department of State Health Services Pesticide Exposure Surveillance in Texas contains information about pesticide poisonings in the state.

A Japanese study found widespread exposures to neonicotinoid residues but intake levels of individual compounds were considered safe (Harada et al., 2016). Neonicotinoid residues have been detected in wetlands, surface water and agricultural soil in several Canadian studies (e.g., Schaafsma et al., 2015,Main et al., 2014). As with all chemical exposures, it is “good practice” to use products as little as possible or to use a less toxic substance. If you must use a pesticide, always follow the safe use and storage directions. Before a pesticide is allowed to be used or sold in Canada, it must undergo a rigorous scientific assessment process to ensure that no harm will occur when pesticides are used according to label directions. All pesticides registered in Canada, including for agricultural, forestry and domestic uses, undergo this level of scrutiny.

As if that weren’t enough, chemical fertilizers can directly degrade your soil, thus damaging plants when used over the long-term. Improper or excessive application of inorganic fertilizers can create pH imbalances and can lead to a buildup of salts and of nitrates which can pollute wells, lakes and streams. The salts also damage microorganisms in the soil, especially the aerobic ones that help with decomposition. This process in turn damages soil structure, leading to increasingly compacted soil. The absence of micro-organisms also results in a thick layer of thatch, and if you do leave clippings to lie, they will probably decompose slowly. One of the most dangerous problems with pesticides is that most do not break down quickly in the environment.

In fact, in one older study, while synthetic pesticides exceeded safety thresholds in 4% or less of produce, rotenone and copper levels were consistently above their safety limits . Second, “natural” does not mean “non-toxic.” Like synthetic pesticides, organic pesticides can also be harmful to your health and the environment. This is an insecticide used in combination with other organic pesticides. It’s naturally produced as a beetle deterrent by several tropical plants and is notoriously toxic to fish.

Fifi said that washing or peeling conventionally grown fruits and vegetables can get rid of some of the pesticides on them. The rule is still under review, but some health experts say we already know enough about the dangers of pesticides to act, especially when it comes to protecting kids. Check out ourFood Label Guidefor more information on the best labels to look for when shopping for foods grown with fewer pesticides. Integrated Pest Management embraces a continuum of practices among farms of all sizes, beginning with identifying pests before spraying.

What Is Soil Organic Carbon Soc?

These include, but are not limited to, studies to characterize acute and chronic toxicity, carcinogenic potential, reproductive and developmental toxicity, immunotoxicty, neurotoxicty, genotoxicity and endocrine disruption potential. The PMRA assessments are also informed by epidemiological evidence, general scientific knowledge and published scientific information. The present study explores the effect of pesticide exposure on the reproductive health and liver function of females participating in agricultural related work. Blood samples were obtained from thirty-five females who were willing donors.

We also maintained and applied standard procedures and using analytical graded products. Khat is an evergreen, mild-narcotic, flowering tree that mostly grows in East Africa. Khat leaves are chewed as a stimulant in many countries, by 5 to 10 million people every day mainly in the Middle East and Eastern Africa [1–3]. The plant is a controlled substance in some western countries, while it is legal in Djibouti, Kenya, Ethiopia, Somalia, and Yemen. The Public Inspection pageon offers a preview of documents scheduled to appear in the next day’s Federal Register issue. The Public Inspection page may also include documents scheduled for later issues, at the request of the issuing agency.

These MSDS should be obtained from either your local pesticide dealer or directly from the chemical manufacturer. Some labels carry technical assistance phone numbers that you can call for further information. Dicamba doesn’t always stay put, and when the chemical drifted into neighboring farms that weren’t using dicamba-resistant seeds, it devastated their crops. The Federal Insecticide, Fungicide, and Rodenticide Act gives the Environmental Protection Agency the authority to approve and regulate pesticide use.

If not properly managed, pests can affect our quality of life in many different ways. Pests can represent a threat to public health and the environment as well as create significant negative impacts to the economy if they are not efficiently controlled. The availability and use of pesticides have the potential to pose risks, both directly and indirectly, to the health, safety and well-being of people in Canada, and to the environment. There is an increasing public and scientific concern that certain chlorinated compounds, recognized as environmental pollutants, may cause estrogen-related neoplastic disease in humans. The main hypothesis has been that certain organochlorines, through their estrogenic actions, might cause breast cancer.
