ABSTRACT

By accumulating heavy metals through emissions of the textile dyeing effluents from the fast-growing textile and dyeing industries, environmental components such as soils, surface and groundwater may become polluted. The aim of the study was to assay the heavy metals in selected textile dyeing industrial effluents in the Rajshahi, Narshindi and Gazipur districts of Bangladesh. An atomic absorption spectrophotometer (AAS) was used to determine the concentration of selected heavy metals. The heavy metals Cr, Mn, Fe, Ni, Cu, Zn, Pb and Cd were studied in textile dyeing effluents in this study. Cr (0.0320 - 0.1334 ppm), Mn (0.1722 - 0.4119 ppm), Fe (2.891 - 4.2826 ppm), Ni (0.0032 - 0.1084 ppm), Cu (0.047 - 0.301 ppm), Zn (0.1648 - 0.3430 ppm), Cd (0.0045 - 0.1400 ppm) and Pb (0.0621 - 0.2900 ppm) were the metal concentrations of textile dyeing effluents for samples Ef1, Ef2, Ef3, Ef4 and Ef5, respectively. The results revealed that among the investigated metals, Fe, Cd and Pd were found at higher levels than the native and international standard values. The findings of the article will be enormously valuable in textile dyeing effluent treatment for building sustainable surface water management in industrial areas.
