Detection of Tolclofos-methyl and Its Decomposition Product (2, 6-Dichloro p-cresol) in Phenolic-Smelling Tomatoes

We investigated the cause of a phenolic smell in tomatoes. But this time 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 0.02-2.2μg/g and 2, 6-dichloro-p-cresol, a decomposition product of tolclofos-methyl, in the range of 0.03-0.15μg/g. We also detected tolclofos-methyl and 2, 6-dichloro-p-cresol, each in the range of 0.01-0.02μg/g, in the tomatoes. 2, 6-Dichloro-p-cresol has a phenolic smell. We concluded that 2, 6-dichloro-p-cresol accounted for the phenolic smell, at least in part.
