| Sources/Uses |
The triazines are broadleaf herbicides. "Atrazine currently is one of the two most widely used agricultural pesticides in the U.S. (based on pounds of active ingredient applied per year). About two thirds of field corn and sorghum acres are treated with atrazine annually for weed control, accounting for most of the 64 to 80 million pounds used per year. Other uses are for turf and lawns, pineapples, sugarcane, wheat, and macadamia nuts." [EPA OPP web site] |

| Comments |
Solid form causes first degree burns on short exposure. [CHRIS] "All the triazines are classified as possible human carcinogens (Group C) based on an increase in mammary gland tumors in female laboratory animals." [EPA OPP web site] The following herbicides have an oral LD50 of >1 gm/kg and have little or no acute toxicity in humans: Alachlor, Amitrole, Ammonium sulfamate, Atrazine, Dalapon, Dicamba, Glyphosphate, Monuron, Oryzalin, Picloram, Propanil, Simazine, etc. [LaDou, p. 570] A mild skin irritant; Injury to the brain, heart, liver, lungs, kidneys, ovaries, and endocrine organs are observed in chronic feeding studies of experimental animals.
