Uptake of organochlorine pesticides by zucchini cultivars grown in polluted soils.
Aim of this trial was to verify the occurrence and the distribution of organochlorine pesticides (OCPs) in zucchini cultivated varieties grown in glasshouses and in open field with different levels of pollutants in soil. Residues of OCPs have been detected in soils and crops in the province of Latina, an intensively agricultural area of Lazio Region, in Italy. The study has been focused at crop harvest in less contaminated glasshouses and during crop life cycle in contaminated field in spring-summer time. Dieldrin distribution in different part of plant is similar among zucchini cultivars grown in contaminated field. In crop grown in field and in glasshouses with soil pollution >0.01 mg/kg, we found dieldrin in all zucchini fruits and flowers, at the same level or higher than the maximum residue limit (RML) fixed by European law for edible vegetables (0.02 mg/kg). Instead in soil with pollution < or = 0.01 mg/kg total OCPs it would be possible to grow zucchini cultivars.
