Examining Human Toxicity of Agricultural Pesticide Use in California
Pesticide use trends in California have shifted drastically in recent decades. As neurotoxic pesticides-such as organophosphates and carbamates- have been phased out of agricultural use, they have been replaced by other pesticides such as pyrethroids, neonicotinoids, and glyphosate (the active ingredient in RoundUp). However, little is known about the relative toxicity of the pesticides that are currently being used most heavily in agriculture. No previous studies have evaluated total pesticide toxicity over time, including whether cumulative toxicity has shifted in conjunction with changes in the types of pesticides being applied. Additionally, no previous studies have assessed trends in use of organic pesticides and potential implications for toxicity. This project seeks to examine the total toxicity to humans of agricultural pesticide use in California and Monterey County from 1990-2017.
