摘要: Abstract The cadmium concentration in different drinking water supplies of Dhaka City is reported. In this study, was extracted from into chloroform after chelation with sodium diethyldithiocarbamate and then back for determination by atomic absorption spectrophotometry (AAS). source below the detection limit (51 μgl −1 ) that supply (tap water) tube-well ranges 1.03 to 1.58 1.71 2.24 ppb, respectively. corresponding zinc content 0.013 0.30, 0.018 3.8 0.042 0.37 ppm. implications these findings are discussed.
