DETECTION OF TOLCLOFOS-METHYL AND ITS DEC OMPOSITION PRODUCT (2,6-DICHLORO-P-CRESOL) IN PHENOLIC-SMELLING TOMATOES

We investigated the cause of a phenolic smell in tomatoes. But this ti me prothiofos and 2,4-dichlorophenol were not detected in the tomatoes . When we analyzed pesticide residues in soil of the tomato field, we detected tolclofos-methyl in the range of 0.02 similar to 2.2 mu g/g a nd 2,6-dichloro-p-cresol, a decomposition product of tolclofos-methyl, in the range of 0.03 similar to 0.15 mu g/g. We also detected tolclof os-methyl and 2,6-dichloro-p-cresol, each in the range of 0.01 similar to 0.02 mu g/g, in the tomatoes. 2,6-Dichloro-p-cresol has a phenolic smell. We concluded that 2,6-dichloro-p-cresol accounted for the phen olic smell, at least in part.
