Other aquatic spp.: LC50 (96 h) for mysid shrimp (Mysidopsis bahia) 0.0057 mg/l; LC50 (48 h) for Eastern oyster (Crassostrea virginica) 2.7 mg/l. Bees: Toxic to bees; LD50 (topical) 1 g/bee. Worms: LC50 (28 d ) 106-176 mg/kg soil. Other beneficial spp.: Toxic to beneficial insects. ENVIRONMENTAL FATE Animals: In mammals, carbaryl does not accumulate in body tissues, but is rapidly metabolised to non-toxic substances, particularly 1-naphthol. This, together with the glucuronic acid conjugate, is eliminated predominantly in the urine and faeces. Metabolism of carbamate insecticides is reviewed. Plants: Metabolites are 4-hydroxycarbaryl, 5-hydroxycarbaryl and methylol-carbaryl. Soil/Environment: Under aerobic conditions, carbaryl at 1 ppm degraded with DT50 7-14 d in a sandy loam and 14-28 d in a clay loam.
