Abstrakt: Carbonyl- 14C-labeled major Bux® isomer, m-(1-methylbutyl)-phenyl methylcarbamate, was studied for 33 days in a model ecosystem devised by R. L. Metcalf and his associates. Bux insecticide rapidly degraded in water with a half-life of less than 4 days at pH 7.9. Most of the metabolites were present as conjugates or other polar metabolites. Bux insecticide was highly toxic to the aquatic animals immediately after application of this compound to the model ecosystem. After 33 days, algae and Elodea plants contained ca. 0.2–1 ppm of insecticide, and living crabs contained ca. 0.02–0.08 ppm of Bux. A clam which died 10 days after application contained ca. 0.3 ppm. It is unlikely that Bux will cause long-term environmental contamination, although it will produce short-term adverse effects on aquatic animals if the compound is applied to water or enters water shortly after application.
