“…Different types of nitrosamines in finished waters have been detected and characterized in several other locations in North America, the United Kingdom, Australia, and Asia. In these studies, NDMA was the most commonly detected, and the concentrations were up to 18.3 ng/L in North America, up to 65 ng/L in Canada (Russell et al, 2012;Krasner et al, 2013;Uzun et al, 2015;Charrois et al, 2007;Zhao et al, 2008), up to 10 ng/L in Japan (Asami et al, 2009), and up to 35.7 ng/L in China (Wang et al, 2010(Wang et al, , 2012. Compared to those surveys, NDEA and NDBA were also two dominant nitrosamines in finished waters in this study and previous reports of China (Wang et al, 2010(Wang et al, , 2012.…”
