Where It Comes From
Applied to rice fields; enters surface water through tailwater and runoff during the growing season [1].
How You Are Exposed
Handling or applying products at work; spray drift near treated fields; drinking private well or surface water influenced by agricultural runoff; small residues on food [1][2].
Why It Matters
Short-term exposure may cause eye/skin irritation, headache, or nausea; long-term high-dose animal studies show liver effects. EPA has not identified thiobencarb as a human carcinogen. It is highly toxic to aquatic life [1][2].
Who Is at Risk
Farm workers and applicators; people living near rice-growing areas; users of untreated private wells influenced by agricultural drainage [1].
How to Lower Your Exposure
Follow label directions and use protective gear when mixing/applying. Keep distance during applications and close windows. Check local water reports; for private wells, consider activated carbon or reverse osmosis treatment certified for pesticide reduction [1][3].
