biostudies-literatureUnknown6Yuan NDrinking water treatment residue (DWTR), a byproduct generated during potable water production, exhibits a high potential for recycling to control eutrophication. However, this beneficial recycling is hampered by unclear metal/metalloid pollution risks related to DWTR. In this study, the pollution risks of Al, As, Ba, Be, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Pb, and Zn due to DWTR application were first evaluated for lake water based on human health risk assessment models and comparison of regulatory standards. The risks of DWTR were also evaluated for sediments on the basis of toxicity characteristics leaching procedure and fractionation in relation to risk assessment code. Variations in the biological behaviors of metal/metalloid in sediments caused by DWTR were assessed using Chironomus plumScientific reports38638https://www.ebi.ac.uk/biostudies/studies/S-EPMC5144140biostudies-literatureApplicability of drinking water treatment residue for lake restoration in relation to metal/metalloid risk assessment.PMC5144140Wang CJiang HYuan NPei YfalseApplicability of drinking water treatment residue for lake restoration in relation to metal/metalloid risk assessment.Drinking water treatment residue (DWTR), a byproduct generated during potable water production, exhibits a high potential for recycling to control eutrophication.
