A study to monitor atrazine (ATZ) and its metabolites (ATZs) (including DEA, deethylatrazine; DIA, deisopropylatrazine; HA, hydroxyatrazine) in drinking water treatment plants from water source to consumers tap in Zhoukou City was undertaken. A total of 20 source water, 36 finished water, and 36 tap water samples were collected during the period from July to August in 2020. Based on the survey results, a human health non-carcinogenic and carcinogenic risk assessment was conducted for adults and children. The results showed that the Î£ATZs concentrations in source water, finished water, and tap water ranged from 0.609 to 55.985ng/L (mean=6.065ng/L), 0.445 to 46.3ng/L (mean=4.507ng/L), and 0.475 to 91.9ng/L (mean=7.139ng/L), respectively. The predominant compounds of ATZs in tap water was ATZ, with a detection frequency of 91.67%, followed by DIA (58.33%), DEA (52.78%), and HA (27.78%). The highest concentrations of Î£ATZs (mean=15.110ng/L) in tap water was found in the Central of Zhoukou City,...
