(Beyond Pesticides, July 25, 2025) The scientific literature shows that microplastics (MPs) and pesticides, both ubiquitous throughout the environment, have synergistic effects that threaten aquatic organisms. This means the combined toxicity of the two substances is greater than the sum of two individual exposures. The most recent study to demonstrate this, published in Ecotoxicology, focuses on the impacts of MPs and chlorpyrifos (CPF), a widely used organophosphate insecticide, on cladocerans, a group of microcrustaceans. As Beyond Pesticides has previously reported, microplastics are found in all environments and threaten not only human health but all wildlife in both aquatic and terrestrial ecosystems. The universal distribution of plastics means that they cannot be avoided. Humans and other organisms take up plastics in the form of microparticles and nanoparticles by inhalation, ingestion, and skin contact every day. Microplastics are about the width of a human hair; nanoplastics are much smaller, about twice the width of a DNA strand. Larger pieces of plastic are ground down to these tiny sizes by weathering, temperature, biological processes, and chemical conditions. (See additional Daily News coverage on the health and environmental hazards of plastics here, here, and here.) The authors of the current study, in exposing two […]

(Beyond Pesticides, April 7, 2025) Throughout the year and historically, the science and policy deficiencies captured by the Daily News paint a dramatic picture of the issues that support the need for strong organic standards on a range of issues, some of which will be under consideration by the National Organic Standards Board (NOSB) when it receives public comments through Monday, April 28. Organic advocates are gearing up to participate in the hearing process and the semi-annual meeting of the NOSB to protect and enhance the integrity of defined, certified, and enforceable organic standards as an alternative to harmful chemical-intensive practices. Because of USDA’s delay in scheduling the NOSB meeting, board members will not have time to review public comments unless they are submitted as soon as possible before the start of the board meeting on April 29. So, Beyond Pesticides is encouraging members of the public to comment early. There are public comment webinars on April 22 and 24 and a deliberative hearing from April 29 through May 1, that concern how organic food is produced. A draft meeting agenda is available here; a more detailed agenda with proposals is available here. Sign up for a 3-minute oral public comment timeslot to let the U.S. Department of […]

(Beyond Pesticides, March 3, 2025) When the United Nations (UN) adjourned the fifth session of the Intergovernmental Negotiating Committee to develop an international legally binding instrument on plastic pollution, including in the marine environment, Inger Andersen, executive director of the United Nations Environment Programme (UNEP), said, “The world’s commitment to ending plastic pollution is clear and undeniable.” She continued, “Here in Busan [Korea], talks have moved us closer to agreeing on a global legally binding treaty that will protect our health, our environment, and our future from the onslaught of plastic pollution.” In March 2022, the UN Environment Assembly adopted UNEA Resolution 5/14 entitled “End plastic pollution: Towards an international legally binding instrument.”  With the Trump Administration shutting down environmental programs and exiting from collaborative international environmental agreements, the work of the world community has taken on elevated importance, given the urgency of health, biodiversity, and environmental crises; so, too, has the work going on at the state level and in local communities across the United States. The interconnectedness of the pesticide and plastic problems was brought into focus recently with a scientific review of articles showing elevated pesticide hazards linked to plastic contamination. A literature review in Agriculture, covering over 90 scientific […]

(Beyond Pesticides, February 25, 2025) A literature review of over 90 scientific articles in Agriculture documents microplastics’ (MPs) increase in the bioavailability, persistence, and toxicity of pesticides used in agriculture. The interactions between MPs and pesticides enhance the threat of pesticide exposure to nontarget organisms, perpetuates the cycle of toxic chemical use, and decreases soil health that is vital for productivity. “The increasing presence of MPs in agricultural ecosystems has raised concerns about their impact on pesticide bioavailability, efficacy, and environmental behavior,” says study author Kuok Ho Daniel Tang, PhD, a global professor in the Department of Environmental Science at the University of Arizona. He continues, “These synthetic particles interact with pesticides through adsorption and desorption processes, altering their distribution, persistence, toxicity, and uptake by plants and other organisms.” Microplastics in the Environment As Beyond Pesticides has previously reported, microplastics are ubiquitous and threaten not only human health but all wildlife in both aquatic and terrestrial ecosystems. The universal distribution of plastics means that they cannot be avoided. Humans and other organisms take up plastics in the form of microparticles and nanoparticles by inhalation, ingestion, and skin contact every day.

(Beyond Pesticides, March 25, 2024) Because of their widespread infiltration into the environment and the bodies of all organisms, including humans, plastics contamination requires a holistic strategy to protect life— with consideration given to practices and chemical use that reduce or eliminate harm. Pesticides and other toxic chemicals are adsorbed (adhered) to microplastics, resulting in bioaccumulation and widespread contamination. This adds to the complexity of the problem, which is largely ignored by federal regulatory agencies. While most environmental policies attempt to clean up or mitigate health threats, new data reinforces the need to stop the pipeline of hazardous chemicals, wherever possible. With new data on the harm associated with plastics and related contamination, it becomes urgently necessary for all government agencies to participate in a comprehensive strategy to eliminate plastics and pesticides. Beyond Pesticides points to the evolving science on plastics contamination and their interaction with pesticides as yet another reason to transition to holistic land management systems that take on the challenge of eliminating hazardous chemical use. Organic land management policy creates the holistic systems framework through which plastics can be eliminated. >> Tell USDA, EPA, and FDA to create strong restrictions on plastics in farming, water, and food.
