Abstract:
Heavy metal pollution is now a days; one of the most serious environmental issues on a world
scale and also in Bangladesh. A study was carried out to determine the status of heavy metals
in non-polluted and polluted soils and vegetables from intensively growing areas of Gazipur
district. Sixty soil samples and sixty vegetable samples were collected from Gazipur district.
Total amount of heavy metals like Pb, Cd, Ni,Co,Cr, and Mn in soils and vegetables were
determined. The soils were also analyzed for texture, pH and organic matter. Data were
analyzed by SPSS software. It was found that the levels of heavy metals in soils varied from
location to location. The mean concentrations of Pb, Cd, Ni, Co, Cr, and Mn in non-polluted
soils were5.16, 0.89, 15.14, 12.84, 21.95, 12.59μg g

, respectively and in polluted soils7.33,

soils were within the limit allowed for maximum acceptable concentration
