Environmental ProfileEcotoxicology:
Algae: EC50 (5 d) 2.20-15.4μg/l.Bees:Non-toxic to bees.Birds: LD50 (8 d) for bobwhite quail 618, mallard ducks >2000 mg/kg. LC50 (8 d) for bobwhite quail 3428, mallard ducks >2000 mg/ kg.Daphnia: LC50 (48 h) 177μg/l.Fish: LC50 (96 h) for bluegill sunfish 21.6, rainbow trout 8.94μg/l.
Environmental fate:
Animals:In rats, 58-62% is excreted in urine and about 25% eliminated in faeces within 72 h. Metabolites were mainly parent and 8-hydroxyquinoline and a small amount of glucuronide and sulfate conjugates.Soil: DT50 2 d (20℃, 63% MWC). No tendency to leach (90% remained in the 0-6 cm top soil layer).Plant:The product does not penetrate and is not translocated after foliar application after one week in lettuce and up to four weeks in apple. No metabolites were observed in the surface wash-off. -
Transport InformationHazard Class:III(Slightly hazardous)
