Abstract
The degradation of fenitrothion under real environmental conditions was studied. Fenitrothion was applied in the irrigation ditches of the Ebre Delta (Tarragona, Catalonia) at an estimated concentration of 200 (situation 1) and 20 μg/L (situation 2) in order to eliminate the american crab (Procamburus clarkii). The evolution of the levels of fenitrothion and the formation of transformation products (TPs) were recorded during the 4 days after application. The TPs formed were 3-methyl-4-nitrophenol, fenitrooxon, and 5-methyl isomer of fenitrothion. The concentration of fenitrothion decayed sharply in 2 h with 6% and 0.3% of the initial concentrations in situations 1 and 2, respectively, and reached a steady state within 10 h with a concentration of 4 and 0.01 μg/L, respectively, which was constant for the 4 days the experiment lasted
