Accumulation of Heavy Metals in Agricultural Crops and Ecological Series of Crops Placement

The accumulation of toxic elements in vegetables and melons grown agriculture, Brassica rapa - turnip, Solanum lycopersicum tomato, Citrullus lanatus watermelon, Capsicum annuum bell pepper, Daucus carota carrots, Cucurbita pepo pumpkin, Cucumis melo melon, also Prunus armeniaca apricot from fruit trees were analyzed. excess maximum allowable concentrations agricultural crops the element As by 1.65-1.75, Cd 1.6-2.3, Cr -1.2-2.35, Cu -1.6-3.3, Ni 1.16-3.53, Pb 1.54-3.08, Al 1.36-3.5, Sb 2.0-33, Se 1.1-3.3 times was established. concentration mercury equal to 0.02 mg/kg, chosen plants this indicator close (MAC). An ecological series vegetable melon (tomatoes → pumpkin turnips peppers watermelons carrots) has been developed for their placement on fields contaminated with heavy metals Se, As, Pb, Cd, Zn, included first class terms degree danger human health, while Ni, Cu, second class, metal Mn third class. Agricultural are placed inverse proportion regularities hyper them.
