Source Tracking and Risk Assessment of Pharmaceutical and Personal Care Products in Surface Waters of Qingdao, China, with Emphasis on Influence of Animal Farming in Rural Areas. Arch Environ Contam Toxicol. 2020 Mar 02;: Authors: Zheng Y, Lu GH, Shao PW, Piao HT, Gai N, Rao Z, Zhao QS, Yang YL Abstract The occurrence and potential sources of pharmaceuticals and personal care products (PPCPs) in surface waters from a large coastal city Qingdao, North China, were investigated. Forty-five compounds were analyzed by high-performance liquid chromatography-tandem mass spectrometry. The results showed that 28 compounds of PPCPs were detected. The most frequently detected compounds were atrazine, clarithromycin, nonylphenol, and bisphenol A with the detection rates > 90%. Paracetamol showed the highest concentration up to 4400 ng/L (mean 152.5 ng/L), followed by ampicillin (max. 2980 ng/L) with the highest mean concentration (229.3 ng/L), iopromide (max. 1744 ng/L, mean 74.5 ng/L), atrazine (max. 1612 ng/L, mean 96.1 ng/L), and bisphenol A (max. 1384 ng/L, mean 78.3 ng/L). The contamination levels and composition profiles of PPCPs along the rivers flowing through rural and urban areas and in seawater showed large spatial variability. Typical source markers and principle component analysis were used to track and differentiate the potential PPCP sources. The emphases of the study were the influence of animal farming in rural ar...
