title: [Occurrence of pesticides in apples of varieties from south-east Poland in the years 1986-1989].
abstract: In years 1986-1989, a total 445 samples apples of late cultivars were examined. Pesticides were extracted with acetone, whereupon they were transferred to dichloromethane. Extracts were analysed using a gas chromatograph equipped with an electron capture detector and a thermo-ionic detector. Moreover, TLC and colorimetric methods were used. The major part of insecticides and fungicides used for orchard protection were examined. Pesticide residues were present in 248 samples; as a rule, they did not exceed 20% of their allowable concentrations in apples. Thus, the occurrence--in the same sample--of two or more pesticides on this level should entail no risk for the consumer's health. In 19 samples the allowable concentrations of pesticide residues were slightly exceeded; in all cases, only MBC was involved.
