Study Finds Exposure to Breast Cancer Chemicals, Including Pesticides, Is Ubiquitous
Study Finds Exposure to Breast Cancer Chemicals, Including Pesticides, Is Ubiquitous
(Beyond Pesticides, October 23, 2026) A study of breast cancer linked to chemical exposures has undertaken an ambitious process to develop a picture of just how exogenous chemicals threaten human breast health, finding that “exposure to potential breast carcinogens is ubiquitous.” The study integrates data from rodent studies of mammary tumors, in vitro analyses of chemicals’ effects on reproductive hormones, chemical production and toxic release statistics, biomonitoring archives and other estimates of exposure. The study encompasses all chemicals, including pesticides, and all modes of exposure, from food and drinking water to air pollution, personal care products and pharmaceuticals. It was published in Environmental Health Perspectives by researchers from the Silent Spring Institute and the University of California, Berkeley Schools of Law and Public Health.
(The study) identifies 485 chemicals linked to breast cancer in pesticides, along with 462 in food, 162 in drinking water, 500 in consumer products, and 142 in pharmaceuticals. (Many chemicals will be found in more than one category.)

With Co-exposure to Microplastics, Adverse Ecological Effects of Pesticides Intensify, Studies Find
(Beyond Pesticides, October 16, 2026) Published in International Journal of Environmental Science and Technology, a comprehensive review highlights how microplastics and nanoplastics (MNPs) are “pervasive soil contaminants with significant potential to alter the environmental fate and ecological impacts of co-occurring pesticides” in terrestrial systems. The research demonstrates that MNPs enhance pesticide persistence in soil, exhibiting stronger effects over time.

Research Reinforces Findings of Pesticides as a Threat to Aquatic Ecosystems, Need for Holistic Solution
(Beyond Pesticides, October 27, 2026) In a study of ecological impairment in agricultural streams, researchers from Germany find that pesticide exposure, co-occurring with habitat degradation, nutrient enrichment, oxygen depletion, and other environmental pressures, contributes to adverse effects on aquatic communities.
“The authors of the original KgM concluded that pesticide exposure was the dominant stressor affecting vulnerable insects and the macroinvertebrate community based primarily on analyses using the SPEARPesticides (SPEcies At Risk) index,” the researchers report.

Similar to Previous Studies, Researchers Find Pesticides Affect Liver Function
(Beyond Pesticides, October 20, 2026) Researchers identify significant increases in liver biomarkers among fruit farmers relative to non-exposed community members. With the understanding that pesticides can drive oxidative stress and other forms of hepatotoxic cell damage/death, increased presence of biomarkers is a clinical manifestation of adverse effects on the liver and has been linked through epidemiological data with “increased risk of non-alcoholic fatty liver disease and hepatocellular carcinoma” among those chronically exposed to pesticides.
45% of fruit farmers spray pesticides up to 10 times/year. Researchers detected 27 pesticide compounds—19 insecticides, seven fungicides, and one herbicide—as well as 10 plant-growth regulator compounds through blood samples. The most detected pesticide compounds are classified as WHO Class II, or “moderately hazardous”:

Contamination of Birds Near Pesticide Use Areas Widespread, with Organic Offering Protection
Contamination of Birds Near Pesticide Use Areas Widespread, with Organic Offering Protection
(Beyond Pesticides, November 3, 2026) Bioindicators are living organisms that reflect the health and quality of the environment in which they live. In a study of passerine birds, commonly known as perching birds or songbirds, researchers from France conclude, “By showing that bird contamination reflects local agricultural practices and proximity, this study supports using passerines as effective sentinels of local environmental pesticide pressure, offering a valuable proxy for assessing ecological exposure in environments shared with human populations.”
Published in Environment International, the findings show that proximity to intensive agricultural areas increases exposure. As the distance from treated areas increases, pesticide contamination within the passerine birds decreases, with the lowest pesticide concentration levels in areas with organic farming. In identifying increased pesticide concentrations in bird species in areas of intensive agricultural areas, the study highlights the implications for disproportionate risks to both farmworkers and residents working and living in or near these areas.

Study of Thyroid Cancers Finds Environmental Contaminants, Including Pesticides, in Tissues of Tumors
(Beyond Pesticides, October 22, 2026) A study of environmental risks factors for differentiated thyroid cancer (DTC), published in Environment International, finds hundreds of environmental chemicals in human thyroid cancer tissues. The results suggest that certain compounds may contribute to thyroid cancer carcinogenesis. 709 environmental chemicals screened, a median of 302 annotated chemicals are found in individual samples, with 442 total environmental chemicals identified that include insecticides, herbicides, and fungicides.
Overall, 442 environmental chemicals were annotated, including insecticides, herbicides, chemical synthesis intermediates, dye intermediates, flavoring or fragrance agents, plasticizers, solvents, combustion byproducts, fungicides, flame retardants, preservatives, polychlorinated biphenyls, lubricants, and per- and polyfluoroalkyl substances. Of these, 40% were potential endocrine-disrupting chemicals.
"..70% of the annotated chemicals do not appear to have undergone formal carcinogen classification by IARC International Agency for Research on Cancer or other agencies,” the researchers say. “The present data suggest that these should be prioritized for carcinogenesis testing.”

Advancing Science on Pesticides, Taking Action in Harmony with Nature, and Sustaining Life
43rd National Forum Series — 2026 (Virtual) about epigenetic effects of pesticides.
Epigenetic changes on DNA molecules is like reading a sentence with a lot of typos. Some typos ar minor and you can still figure out what is written, some are more major and lead to errors of interpretation.
You can view the video only to November 27, 2026. I assume the session recording and materials will remain available at this link. 2h 29 minutes video.
Entomologist Hongmei Li-Byarlay, PhD, along with coauthor Rameshwor Pudasaini, PhD, are the authors of the chapter titled ‘The underlying mechanisms of Varroa resistance in honey bee colonies’ in the recently published book Threats to Pollinator Abundance and Diversity. The chapter focuses on the multiple, interacting factors and mechanisms that adversely impact honey bee colony success. In particular, environmental factors can weaken honey bee resistance to Varroa mites, further threatening honey bee health.

Decade of residential pesticide exposure tied to blood pressure and cholesterol changes
Decade of residential pesticide exposure tied to blood pressure and cholesterol changes
(Bioengineer.org, October 24, 2026) A decade of living near agricultural pesticide applications is associated with measurably higher blood pressure and lower HDL cholesterol among midlife women in one of California’s most intensively farmed regions, according to a new longitudinal study published in the Journal of Exposure Science & Environmental Epidemiology.
List of pesticide classes and individual pesticides studied in article linked in comments below.
' In exploratory analyses, QGCOMP weights pointed to manganese fungicides and, to a lesser extent, neonicotinoid insecticides as the largest contributors to the blood pressure associations, with carbamate insecticides and glyphosate-based herbicides contributing most to the HDL cholesterol association.'
'Experimental evidence offers a plausible biological thread: many pesticide classes share the capacity to generate oxidative stress, producing reactive oxygen and nitrogen species that overwhelm endogenous antioxidant defenses. Oxidative injury to the endothelium can promote vasoconstriction and elevated blood pressure, while lipid peroxidation can impair HDL function and reverse cholesterol transport.'filed under cardiovascular

Family hospitalized after use of a fumigant in adjacent field
Une famille hospitalisée après l'épandage d’un pesticide dans un champ voisin (Emilie Marcoux, Le Nouvelliste, 5 Novembre 2026,on FB by Victimes ds Pesticides du Québec) Family hospitalized after use of a fumigant in adjacent field
Le produit en cause serait la chloropicrine, un pesticide utilisé en fumigation, mortel par inhalation. Il est homologué au Canada, mais interdit dans l'Union européenne depuis 2011. Il est même interdit par la Convention sur les armes chimiques.
Cet incident, qui n'est malheureusement pas un cas isolé, soulève de sérieuses questions sur la protection des populations riveraines et l'encadrement des pesticides.
Alors que le projet de loi C-31 pourrait affaiblir les mécanismes de surveillance et de réévaluation des pesticides, le Canada risque de prendre encore plus de retard en matière de protection de la population. Faudra-t-il attendre d'autres intoxications pour agir ?

Translation: chloropicrin is a toxic fumigant. 6 chloropicrin containing pesticides are registerd in canada as of 9 November 2026. It has been banned in Euroep since 2011, and is also banned by the Chemical Weapons Convention. This is not an isolated case. Bill C-31 aims to stop mandatory psticie re-valuations every 15 years.

Parkinson s Europe opposes the Omnibus plan to abolish periodic pesticide review
Parkinson's Europe opposes the Omnibus plan to abolish periodic pesticide review (PAN Europe- pane - November 9, 2026)
Parkinson's Europe has called for periodic safety checks on pesticides to be maintained. The European umbrella organisation sent a letter to policy-makers to reject the deregulating Food and Feed Omnibus proposal, a "dangerous step backwards for European public health.” By dismantling these safety reviews, the Omnibus proposal would remove a key tool for protecting citizens, specially farmers and people in rural communities, the organisation warns.
SNAP Comment: It's not good for Europe, it isn't good for Canada either and yet we want to do the same... 'n a position paper sent to the European Parliament and the Council (Members States), Parkinson's Europe calls for preserving the mandatory, periodic scientific reassessment of substances used in pesticides. The Omnibus proposal would replace these periodic reviews with unlimited approval periods and theoretic ad-hoc reviews. This means "approved pesticides will be deemed safe indefinitely unless proven otherwise, violating the precautionary principle and removing any incentive for the chemical industry to reassess its products as new science emerges."
"Such a system cannot safeguard human health as effectively as the current periodic framework. The EU must retain its leadership in high environmental and health standards. Parkinson's Europe urges policymakers to reject the proposal accordingly”, the organisation concludes.filed under Legislation/regulatory/Europe
