説明

The photodegradation of benthiocarb (S-4-chlorobenzyl N, N-diethythiocarbamate) under ultraviolet lights or sunlight was investigated using 14C-labelled and unlabelled compounds. Benthiocarb in the aqueous solution was more rapidly degraded by irradiation with ultraviolet lights than seven common pesticides tested. The irradiation resulted in the formation of many degradation products such as benthiocarb sulfoxide, desethyl benthiocarb, 4-chlorobenzyl alcohol, 4-chlorobenzaldehyde, 4-chlorobenzoic acid, 4-hydroxy analogues of the alcohol, the aldehyde and the acid, 8 other identified compounds and about 20 unidentified compounds. Among these, 4-chlorobenzaldehyde and the alcohol were the major products. The degradation in the aqueous solution under sunlight was also considerably rapid, and most of the degradation products detected were the same as those produced by irradiation with ultraviolet lights. The irradiation on the thin film of benthiocarb on glass plate also resulted in the formation of the same degradation products as those in the aqueous solution.
