摘要：Heavy metals due to their non-biodegradability and having physiological effects on living organisms are particularly important. The aim of this study was evaluated the concentration of some heavy metals such as lead, cadmium and chromium in vegetable species which are planted in Ahvaz, Iran and comparison of them with recommended guidelines. Seventy samples from each basil, radishes and purslane were gathered during 2013 from farmlands. Samples were digested according to reported instruction of AOAC official methods and analyzed by graphite furnace atomic absorption spectrometer. Results showed that lead, cadmium and chromium contents in vegetables were in the range of 9.7- 11.13, 1.973.20, and 0.12- 0.17 mg/kg, respectively. Statistical analysis showed a significant difference between mean concentration of lead and cadmium in vegetables and the permitted value (P<0.05). By comparing the result with the permissible limit which is reported by WHO/FAO, lead and cadmium contents of the vegetables are above the recommended value.
