The peripheral rivers of Dhaka city became highly polluted because of industrialization and urbanization to a greater extent in the last few ***,an attempt has been taken to measure 48 elements in water of the river Buriganga using the ICP-MS method for the first ***,it could be the reference values for future research in *** of the 48 elements,the following metals are given more attention because of their detrimental effects on living organisms and for discussing their aquatic chemistry in polluted water body:Be,na,Al,Cr,Mn,Fe,Ni,Cu,Zn,Cd,Ba,Hg,Pb,Bi and *** revealed that metals’concentrations in water in the monsoon were less than that of the winter,however,Cr and Fe were found at below detection limits in the winter that is *** parameters of the river water such as pH,dissolved oxygen play vital roles for hydrolysis reactions in the stagnant water *** products of metal ions having low values of solubility products(K sp),for example,iron(III)hydroxide,chromium(III)hydroxide,phase out through precipitation *** study also detects and quantifies total concentrations of Hg and U in water of the river Buriganga for the first *** and correlation matrix results provided potential sources of the relevant *** of hydrolysis and precipitation reactions for metal ions in the polluted river water are also discussed.
