Özet:

 

Contamination of heavy metals in the aquatic environment has been considered a global crisis due to their indestructible, toxic, and persistent characters. To evaluate the level of contamination of different lakes of Matlab Uttar Upazila of Chandpur district in Bangladesh, this study was conducted estimating the concentration of worldwide alarming heavy metals (i.e. Pb, Cd, Cr, Cu, As, Zn, and Fe) in both surface water and sediments. The concentrations of the selected metals were determined by atomic absorption spectrometry (AAS). The obtained results indicated that metal concentrations were higher in sediment samples than in the lake water samples. In both cases, the concentration of Fe was maximum whereas Zn and Cd were found in the lowest amount in water and sediment samples, respectively. Almost all the selected metals in water were found lower than the maximum permitted concentrations of drinking water standards proposed by Bangladesh Standard (DOE, 2002), EC (1998), WHO (2004), and USEPA (2009) excepting Fe in all the lake water and Pb in Borokinachok lake water suggested that the examined lake water samples were not fully safe for daily activities, though these lake water can be used for irrigation purposes as they retain standards. In sediment samples analysis, the concentrations of studied heavy metals followed the order of Fe> Zn> Pb> Cu> Cr>As>Cd. Comparing with the sediment quality guidelines of USEPA, it was found that the collected sediments were not polluted for Zn and Cd whereas concentrations of some metals (As, Cr, Cu, and Pb) in different sediments indicated moderate to a high level of pollution. From the overall findings, it can be proposed that the selected lakes of Matlab Uttar Upazila of Chandpur district were contaminated and might pose an adverse effect on the ecology of the studied lakes.
