Keywords: Pesticides | organochloryde residues

The pesticides belonging to organo-chloride group was the subject of many controversial argues during their utilization in agriculture. Their extremely high toxicity both for human beings and animals consuming those produce and also for the useful entomo-fauna in that agro-system led to their gradual elimination, their utilization being now forbidden. The organo-chloride substances observed were: α. β. γ HCH – hexachlorine- cyclohexane, op and pp DDE (orto-para and para-para dichlor-diphenil-dichloretena). op and pp DDD (orto para and para para dichlor-diphenil-dichloretan). op and pp DDT (orto para and para para dichlordiphenil trichlor etan). The pesticides involved were used many years ago (for instance DDT) or they were applied in soil before tree planting (ex. Sinolintox based on HCH or against the soil pest (Melolontha melolontha, Grillotalpa grillotalpa. Otyorincus spp. larves) following the laboratory analyses they were found in fruit. This paper show the data recorded with the laboratory analyses done for apple, sweet cherry, strawberry and currant to determine the residues of organo-chloride pesticides and to classify then in the admitted limits according to present regulations.
