The issue of microplastic contamination in organic food systems is a critical issue to Beyond Pesticides, including through advocacy in the Spring 2026 National Organic Standards Board (NOSB) meeting. According to the authors, microplastics and pesticides are the most studied pairing, followed by pathogens, heatwaves, and pharmaceuticals, in descending order. There are numerous synergistic/additive effects, including stronger genotoxicity in Ceriodaphnia dubia (see here), oxidative and metabolic disruption in zebrafish with penthiopyrad (see here), and immune damage in carp with emamectin benzoate. There are numerous synergistic/additive effects, including stronger genotoxicity in Ceriodaphnia dubia (see here), oxidative and metabolic disruption in zebrafish with penthiopyrad (see here), and immune damage in carp with emamectin benzoate. A study published in Ecotoxicology demonstrates the adverse impacts of MPs and chlorpyrifos (CPF), a widely used organophosphate insecticide, on cladocerans, a group of microcrustaceans.
