Vegetables in Peshawar, northern Pakistan are found to be
contaminated with nickel, lead, cadmium and chromium with concentrations of
30.14, 27.49, 27.67 and 7.56 mg per kg, respectively which are more than the
standard level and pose threat to human health. Farmers are using wastewater
for irrigation which makes the soil more fertile but also makes polluted.
