Where It Comes From
Seed treatments, orchards, ornamentals, turf/golf courses; sometimes as a wildlife/animal repellent and in rubber manufacturing [2][3].
How You Are Exposed
Mixing/applying products; touching treated plants or soil; spray drift from nearby applications; residues on food; dust or water near farms [1][2].
Why It Matters
Can cause skin/eye irritation, headache, nausea, or dizziness; repeated/high exposure may affect nerves or trigger allergic skin reactions. Animal studies show reproductive/developmental effects. EPA has not classified it as a human carcinogen [1][2][3].
Who Is at Risk
Farmworkers, applicators, seed‑treatment and turf workers; people living near treated fields; pregnant people and young children [1][2].
How to Lower Your Exposure
Follow label directions; wear chemical‑resistant gloves and eye/skin protection when handling; keep kids/pets off treated areas until dry; wash hands, work clothes, and produce; consider certified water filters if pesticides are a local concern [1][2][3].
