其他摘要：Dietary exposure to several heavy metals such as Cd, Cr, Pb, As represents a risk to human health through the consumption of vegetables. Due to the possible risks for the human body, contamination of soils as well as drinking and irrigation water has been the subject of many researches. In this study, the analysis of heavy metals content from soil, water and vegetable samples from households in Ilfov County it was carried out. As a result, no contamination of soil and water with heavy metals was observed. Cadmium content is above the maximum allowable limit for all analyzed vegetables, excepting cabbage and green onion. Two lettuce samples have an alarmingly high content of lead, the values being even 10 times higher than the maximum admissible limit of 0.3 mg/kg. The high values obtained for chromium content in lettuce and radish samples raise serious questions about possible contamination. Arsenic content values ranged between 0.87 and 7.69 mg/kg, which also represents high values. Based on the transfer factor (TF) calculated the strongest accumulation of the metals was in lettuce.
