Background & Aims of the Study: Vegetables and Cereals are considered vital for properly-balanced diet given that they deliver vitamins, minerals, nutritional fiber, and phytochemicals. This study aimed to assess the concentration of As, Cu, Cd, Pb, Cr and Hg in common vegetables and cereals in urban open markets in Varanasi district, India

Materials & Methods: Total 260 edible portions of vegetable samples of 13 species were collected in March to October, 2016 from predefined market sites. These samples classified into roots, stems, leafy vegetables, fruits, and legumes. These samples (unwashed, acetic acid washed and boiled) were assessed using atomic absorption spectrophotometer. The statistical evaluations were carried out using the IBM SPSS 21.

Results: The results obtained reveal that unwashed vegetables and cereals as compared to washed and boiled samples contain higher trace metal concentration. The order of heavy metal concentration was observed in Cu>Pb>Cd>As in vegetable and cereals samples. Hg and Cr were not detected in any samples. The mean value of Cu, Cd and Pb in unwashed and washed vegetables and cereals were lower than PFA standard except As, whereas in boiled vegetables and cereals are lower than PFA standard but the mean value of Cd and Pb were many folds higher than the EU standard at all the market site samples. Leafy vegetables were found to contain the highest metals values especially Spinacia oleracea followed by roots vegetable like Brassica rapa, at all the studied sites. The market sites MS3 located in the vicinity of industrial zone and in proximity to national highway showed elevated levels of trace metals concentration in the vegetables and cereals as compared to other market sites.

Conclusions: The results showed that, the As, Cu, Cd and Pb concentration were reduced to about 12.5%, 5.87%, 11.36% and 10.42% of the initial concentrations by 2% acetic acid washing and to 25%, 21.87%, 20.45% and 16.67% of the initial concentrations by washing followed by boiling. The boiled vegetables and cereals may reduce the risk of trace metal intake from the vegetables and cereals significantly.
