Analysis of nitrosamines in water by automated SPE and isotope dilution GC/HRMSOccurrence in the different steps of a drinking water treatment plant, and in chlorinated samples from a reservoir and a sewage treatment plant effluent

Occurrence and profiling of multiple nitrosamines in source water and drinking water of China

“…NDMA has been widely investigated in drinking water in Canada (Zhao et al, 2008), the United States (Mitch et al, 2003), and Japan (Asami et al, 2009). The concentrations of NDEA have been reported in only several countries and regions, in drinking water (3.7-12.9 ng/L) (Jurado-Sanchez et al, 2010;Planas et al, 2008) and domestic wastewater (0.132 μg/L) (Hartmetz and Slemrova, 1980). Although other nitrosamines including NMEA, NDPA, NMor, NPip, NPyr, NDBA, and N-nitrosodiphenylamine (NDPhA) have been investigated in several drinking water treatment plants (DWTPs) (Wang et al, 2011) and a digestive system cancer region (Ma et al, 2012), due to the lack of a detailed national survey, information regarding the occurrence and concentration levels of multiple nitrosamines in different treatment types of DWTPs across major watersheds in China is still very limited.…”

Analysis of N-nitrosamines in water by isotope dilution gas chromatography–electron ionisation tandem mass spectrometry

“…The most common alternative to this has been analysis by high pressure liquid chromatography with tandem mass spectrometry (HPLC-MS/MS) [22][23][24]. Other advanced methods have included gas chromatography-high resolution mass spectrometry with EI [25] and nanoelectrospray ionisation (NSI) with high-field asymmetric waveform ion mobility spectrometry with time-of-flight mass spectrometry [26]. However, surprisingly little attention appears to have been paid to the possibility of improved sensitivity of a low resolution triple-quadruple GC-MS/MS method using EI.…”

Chlorine for Water Disinfection: Properties, Applications and Health Effects

“…Mainly due to the strict regulations, there have been an increasingly efforts to develop a new analytical methods for the detection of DBPs at lower levels. Highfield asymmetric waveform ion mobility spectrometry (FAIMS)/ESI-MS has been successfully applied to measure HAA, bromate, chlorate, iodate and nitrosamine in drinking water with lower ng/L detection limits (Ells et al 2000;Gabryelski et al 2003;Yuan et al 2009;Planas et al 2008;Barnett et al 1999). …”
