The DBP exposome: Development of a new method to
We developed a new gas chromatography (GC)-mass spectrometry (MS) method that simultaneously quantifies 39 priority unregulated DBPs from six different chemical classes (haloacetaldehydes, haloketones, haloacetamides, haloacetonitriles, halonitromethanes, and iodinated-trihalomethanes) and analyzes unknown DBPs with mass accuracy

The DBP exposome: development of a new method to simultaneously
Also, very few studies conduct comprehensive non-target analyses of unknown DBPs to characterize the complete DBP exposure (the exposome). We developed a new gas chromatography (GC)-mass spectrometry (MS) method that simultaneously quantifies 39 priority unregulated DBPs from six different chemical classes (haloacetaldehydes, haloketones

- Which spectrometry methods are used for DBP analysis?
- Gas chromatography– and liquid chromatography–mass spectrometry are the most frequently used approaches for DBP analysis. High-resolution mass spectrometry techniques are becoming popular for exploring the chemical structures of unknown DBPs.
- What methods are used to analyze drinking water disinfection by-products (DBPs)?
- Recent literature regarding methods for analyzing drinking water disinfection by-products (DBPs) is critically reviewed. Gas chromatography– and liquid chromatography–mass spectrometry are the most frequently used approaches for DBP analysis.
- Which sample preparation methods are used for non-target analysis of DBPs?
- Other sample preparation methods that may be applied for non-target analysis of DBPs are liquid–liquid extraction (LLE) approaches, freeze-drying, and rotary evaporation.
- How do anthropogenic compounds form DBPs?
- Similarly, DBPs have been investigated from anthropogenic compounds, such as pesticides, pharmaceuticals, and UV filters, which can emerge from treated wastewater and enter downstream drinking water sources to form DBPs during drinking water treatment .
- What are disinfection by-products (DBPs)?
- Policies and ethics Disinfection by-products (DBPs), formed during drinking water treatment, are ubiquitous in disinfected drinking water and are generally found at levels 1,000-fold higher than other emerging contaminants like pharmaceuticals and per- and poly-fluoroalkyl substances...
- Which DBP classes have been identified using GC-HRMS?
- Using GC-HRMS, important new DBP classes have been identified, including (halo)aldehydes, (halo)ketones, and >C2 haloacids [32, 33], halonitromethanes , iodo-acids , iodoalkanes , halopyrroles , haloacetamides , iodoacetaldehyde , N -chloroacetamides , and most recently, halocyclopentadienes [41, 42].
