Health, Pesticide Adjuvants, and Inert Ingredients: California Case Study Illustrates Need for Data Access

Abstract

Within California, APNOHO is applied in more than 150 adjuvant products. Nationwide, it is used as an inert ingredient in at least 650 pesticide products. Exposure to APNOHO is associated with endocrine disruption, birth defects, and aquatic toxicity. We suggest that the case of APNOHO illustrates the larger problem of a lack of publicly available data on use and toxicity of many adjuvants and pesticide inert ingredients. We recommend that researchers and regulators include adjuvants and inert ingredients when evaluating pesticide hazards, including endocrine disruption. We also recommend regulatory requirements to identify all ingredients on product labels. https://doi.org/10.1289/EHP10634.
