Where It Comes From
Used before planting in agriculture, turf, nurseries, and mushroom houses; it decomposes in soil to MITC, which can move into air near treated areas [2][3].
How You Are Exposed
Breathing vapors during or after application; skin/eye contact with treated soil or equipment; accidental releases that affect nearby air or water; workplaces handling the product [1][2][3].
Why It Matters
Can cause burning eyes, sore throat, cough, headache, nausea; may trigger asthma or severe breathing problems at higher levels; some people develop persistent airway reactivity after a significant exposure [1][2][4].
Who Is at Risk
Applicators and fieldworkers; people living or working near treated fields; children and anyone with asthma/COPD; workers in enclosed spaces like greenhouses or mushroom houses [1][2][3].
How to Lower Your Exposure
Follow posted fumigation notices and buffer zones; stay indoors and close windows during nearby applications; avoid treated areas until re‑entry times end; ventilate enclosed spaces; workers should use required PPE and training [2][3][4].
