STUDIES ON THE CONTENT OF METALS AND PESTICIDES IN FRUIT GROWING AREAS AND THEIR ECOTOXICOLOGICAL IMPACT

摘要

The selected substances have a high degree of toxicity. Their toxic effects pose serious risks to human health through the effects of consecutive mutations and genotoxic exposure to pesticides of organic origin, which may lead to the emergence of cancer in various tissues and organs. Atomic absorption spectroscopy was proposed for the determination of metals in water samples collected from two different points before and after the plants treatment (spraying fruit trees). The results obtained using the spectrometer reveal a high content of Fe and Pb in samples collected from the waters of the River Dambovita. The values of concentrations is higher than the maximum permissible limits of iron (about 10 times), and lead (2 times). The results obtained for the assay of metals were correlated with the determination of pesticides using HPLC. Many pesticides are known to have a high metal content; accordingly, the concentration of Pb in water in agroecosystems can be attributed to this type of treatment with pesticides.
