“…Recent examples include Hung et al [20] and Llop et al [21]. 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].…”

, S. J. (2012). Analysis of N-nitrosamines in water by isotope dilution gas chromatography-electron ionisation tandem mass spectrometry. Talanta, Analysis of N-nitrosamines in water by isotope dilution gas chromatography-electron ionisation tandem mass spectrometry a b s t r a c t A method has been developed for the determination of eight N-nitrosamines in drinking water and treated municipal effluent. The method uses solid phase extraction (SPE), gas chromatography (GC) and analysis by tandem mass spectrometry (MS-MS) with electron ionization (EI). The target compounds are N-nitrosodimethylamine (NDMA), N-nitrosomethyethylamine (NMEA), N-nitrosodiethylamineThe use of direct isotope analogues for isotope dilution analysis of all analytes ensures accurate quantification, accounting for analytical variabilities that may occur during sample processing, extraction and instrumental analysis. Method detection levels (MDLs) were determined to describe analyte concentrations sufficient to provide a signal with 99% certainty of detection. The established MDLs for all analytes were 0.4-4 ng L À 1 in a variety of aqueous matrices. Sample matrices were observed to have only a minor impact on MDLs and the method validation confirmed satisfactory method stability over intra-day and inter-day analyses of tap water and tertiary treated effluent samples.

“…We further developed the biofilm into a platform for treating refractory pollutants that escape or are modified through the upstream treatment process and can even pass through RO membranes. Currently micropollutants that pass through NF and RO membranes, such as N-nitrosodimethylamine (45) and 1,4-dioxane (46), must be treated using even more advanced techniques such as high-intensity UV radiation (47).…”

Membrane systems are used increasingly for water treatment, recycling water from wastewater, during food processing, and energy production. They thus are a key technology to ensure water, energy, and food sustainability. However, biofouling, the build-up of microbes and their polymeric matrix, clogs these systems and reduces their efficiency. Realizing that a microbial film is inevitable, we engineered a beneficial biofilm that prevents membrane biofouling, limiting its own thickness by sensing the number of its cells that are present via a quorum-sensing circuit. The beneficial biofilm also prevents biofilm formation by deleterious bacteria by secreting nitric oxide, a general biofilm dispersal agent, as demonstrated by both short-term dead-end filtration and long-term cross-flow filtration tests. In addition, the beneficial biofilm was engineered to produce an epoxide hydrolase so that it efficiently removes the environmental pollutant epichlorohydrin. Thus, we have created a living biofouling-resistant membrane system that simultaneously reduces biofouling and provides a platform for biodegradation of persistent organic pollutants.

“…Nonetheless, UV irradiation can be used to limit the concentration of NDMA and NDELA in process wastes [Plumlee et al, 2008] as well as in the water wash sections [Knuutila et al, 2013]. It has been observed that the acidic solution favours UV absorption and thereby the decomposition of nitrosamines [Xu et al, 2009b].…”

The use of amine absorption in carbon capture technologies is related with the formation toxic and potentially carcinogenic amine degradation products such as nitrosamines and nitramines. These substances can be created within both the solvent and the atmosphere when air components (mainly NOx) and amines react with each other. These substances may pose environmental and health risks depending on the level and duration of the exposure. In this paper, formation and occurrence of nitrosamines and nitramines in carbon capture plants were described. Emission reducing technologies have been also mentioned. Furthermore, an overview of experimental data of emission of nitrosamines and other major degradation products has been pointed out.
