During post-monsoon, none of the samples exceeded 50 µg L−1, but eight of them exceeded 10 µg L⁻¹. The Fe removal efficiencies of AIRPs were evident in more than 80% samples. Although As removal efficiency was found to be substantial, a cancer risk assessment indicates that hazard quotient (HQ) and carcinogenic risk (CR) of As in treated water for adults and children are above the threshold limits. Thus, additional reductions of As concentrations in treated water are needed to further reduce the excess cancer risk due to As in drinking water. Since 55% and 40% of the AIRPs were unable to remove As < 10 µg L⁻¹ during pre-monsoon and post-monsoon, further improvement including changes in AIRP design, regular cleaning of sludge, and periodic monitoring of water quality are suggested. Future research is needed to determine whether these modifications improve the performance of AIRPs.]]> Tue 15 Nov 2022 15:04:48 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:38079 Tue 03 Aug 2021 15:12:30 AEST ]]>
