Season- and year-wise distribution of some trace metals and anions in Gulshan Lake, Bangladesh
A study was conducted to quantify some trace metals and anions in Gulshan Lake, Bangladesh over five years. The heavy metals, i.e. Pb, Cd, Cr, Co, Ni and Cu, were found below detection limit. The concentration ranges of other metals including anions were 170-1280 g/L for Fe, 30-190 g/L for Mn, 2...

| Summary: | A study was conducted to quantify some trace metals and anions in Gulshan Lake, Bangladesh over five years. The heavy metals, i.e. Pb, Cd, Cr, Co, Ni and Cu, were found below detection limit. The concentration ranges of other metals including anions were 170-1280 g/L for Fe, 30-190 g/L for Mn, 24-63 g/L for Zn, 4-6 mg/L for phosphate, 10-15 mg/L for sulphate, 17-39 mg/L for chloride and 0.20-0.30 mg/L for fluoride. No clear trend in concentration of detected metals and anions, sampling-site-, season- or year-wise, was observed for the period of 2002 and 2004 - 2007. All measured concentrations were found to be well below drinking water standards. |
