Hazards Identification
Rat, Mouse and Dog Feeding Studies: Two-year feeding studies with rats
(25, 35, 100 and 300 ppm) and dogs (25,100, 1,500 ppm) resulted in a
no-effect level of 100 ppm. There were no indications of carcinogenic effects
in the rat or dog study, or in mice fed at 20, 800, and 3,200 ppm for 2 years.
Reproduction Studies: A three-generation study in rats (at 35, 100, and 300
ppm) showed no influence on reproduction.
Teratogenicity Studies: In tests on rabbits (at 15, 45, and 135 mg/kg/day)
and rats (at 15, 50, and 100 mg/kg/day) metribuzin had no embryotoxic or
teratogenic effects.
Mutagenicity Studies: Tests in vitro (Ames, E.Coli), in vivo (Chinese
Hamsters, spermtogonia test), and in mice (dominant lethal test) showed no
mutagenic activity.
 
 
 First Aid Measures
Inhalation: If inhaled, remove to fresh air. If not breathing, give
artificial respiration. If breathing is difficult, give oxygen. Call a physician.
Skin Contact: Flush skin with water after contact. Wash contaminated
clothing before reuse.
Eye Contact: In case of contact, immediately flush eyes with plenty of water
for at least 15 minutes. Call a physician.
Ingestion: If swallowed, immediately give 2 glasses of water and induce
vomiting. Never give anything by mouth to an unconscious person. Call a
physician.
 
Fire-Fighting Measures
Extinguishing Media: Water, Water Spray, and Dry Chemical.
Fire Fighting Instructions: Wear self-contained breathing apparatus. Wear
full protective equipment. Use water spray. Runoff from fire control may be a
pollution hazard.
