Abstract:
The study reveals the most important nitrate sources of agricultural origin which often pollute food stuffs and drinking
water. In areas of intensive nitrate fertilization and livestock breeding, crops and depth water become overloaded with nitrates.
The nitrate content of carrot, spinach, lettuce, cabbage, and parsley experimentally fertilized with various doses of nitrogen
was measured at their harvest. The upper and deep layers of ground water in some settlements of Banat County (Romania) were
also sampled and analysed for nitrates using the Griess method. The obtained results showed linear correlation between the
nitrogen doses used as fertilizer and the nitrate content of vegetables and water samples. The values of the nitrate content
of vegetables varied and depended on the analysed species, too.
