摘要
We measured the contamination levels with a broad gamma of pesticides in water, soil and foodstuff from Central Romania. Organochlorine, triazine, carbamate, phenoxy acid and organophosphorus pesticides were analyzed in water, soil and foodstuffs samples. Among the most detected pollutants, we found pesticides prohibited in the European Union, such as isomers of hexachlorocyclohexane (HCHs) and DDT, together with their metabolization products. Detectable concentrations of diazinon (20 ng/l), dichlorvos (20 ng/l) and alpha-HCH were measured in rivers. Drinking water samples from fountains and tap-water also contained alpha-HCH (6 ng/L) and gamma-HCH (4 ng/L). The DDT and DDE concentrations in soil varied between 20 mu g/kg and 50 mu g/kg. Concentrations of alpha-HCH and beta-HCH in foodstuffs were 248 mu g/kg and 78.3 mu g/kg, respectively, both exceeded the Romanian reference value (100 mu g/kg for alpha-HCH and 50 mu g/kg for beta-HCH). Organochlorines, such as DDT and its metabolization product DDE, were present in almost all foodstuff samples (except for honey), and high values (222 mu g/kg for DDT and 35.3 mu g/kg for DDE) were measured in eggs.
