Environmental Fate
Biological. In the presence of suspended natural populations from unpolluted aquatic
systems, the second-order microbial transformation rate constant determined in the laboratory
was reported to be 6 ′ 10–13 L/organisms-hour (Steen, 1991).
Soil. Probably degrades via ring hydroxylation and subsequent ring cleavage. Persistence
in soil is limited to approximate 6–8 weeks (Hartley and Kidd, 1987). Under
laboratory conditions, the half-lives in soil were 30, 48 and 59 days at pH 4.85,
