Abstract: Wastewater-based epidemiology combining with a population model based on hydrochemical parameters was applied in 10 wastewater treatment plants (WWTPs) in Jilin province, China. Population of WWTPs served was calculated by the model including three hydrochemical parameters ammonia nitrogen, chemical oxygen demand, and total phosphorus. The population model was constructed by using analytic hierarchy process to calculate weight factors of each hydrochemical parameters equivalent population. The size of population estimated by the model showed the highest correlations with cotinine mass load (r

Abstract: Illicit drugs and their metabolites have recently been recognized as an emerging group of contaminants due to their potential ecotoxicological impact in aquatic ecosystems. To date, information on the occurrence of these compounds in the aquatic environment of China remains limited. In this study, we collected surface water s les from 36 rivers in north China that discharge into the Bohai Sea and north Yellow Sea and measured the concentrations of hetamine-like compounds, ketamines, cocainics, and opioids. The occurrence and spatial patterns of these substances show significant differences between the rivers and regions. Two designer drugs, meth hetamine (METH) and ketamine (KET), were the most abundant compounds detected in the entire set of s les (detection frequency of 92 and 69 %). The concentrations of METH and KET ranged from <0.1 to 42.0 ng L(-1) (mean = 4.53 ng L(-1)) and <0.05 to 4.50 ng L(-1) (mean = 0.49 ng L(-1)), respectively. The high detection frequencies of METH and KET are consistent with the fact that they are the main illicit drugs consumed in China. The high concentrations of these illicit drugs and their metabolites were found in areas that have a high population density. The riverine input of total illicit drugs into the Bohai Sea and north Yellow Sea was estimated to be in the range of 684 to 1160 kg per year.

Abstract: Sewage epidemiology is a real-time tool used to monitor tobacco consumption. In this study, we investigated the tobacco consumption in eight cities in Jilin province using sewage epidemiology. We collected influent wastewater s les from ten wastewater treatment plants (WWTPs) that serve nearly four million people. Mean nicotine (NIC) loads ranged from 1.42 to 14.2mg/d/capita, whereas mean cotinine (COT) loads showed lower levels with 0.33 to 2.15mg/d/capita. Population size was estimated to provide an accurate and real-time population based on ammonia nitrogen (NH
