Where It Comes From
Turf and ornamental products and agricultural uses; residues in soil and runoff near treated areas [1][2].
How You Are Exposed
Mixing or spraying products; skin contact with treated grass/soil; breathing spray drift; eating small residues on food or in water [1][2].
Why It Matters
Can irritate eyes/skin and is harmful if swallowed; repeated high doses caused liver effects in animals. EPA sets limits to keep dietary risk low; it is highly toxic to fish and aquatic invertebrates [1][2].
Who Is at Risk
Applicators, groundskeepers, nursery/rice workers; children and pets on freshly treated lawns; people living near frequently treated turf [1][2].
How to Lower Your Exposure
Follow label directions and wear gloves/long sleeves; keep people and pets off treated areas until dry or the re-entry interval ends; avoid use before rain or near water; wash hands and remove shoes after lawn care; rinse produce [1][2].
