Cross-reactions identified within these groups of DDAbs are shown in Tables 1 and 2. Cross-reactions, many quite strong (S) were observed among DDAbs specific for drugs
Examples of DBP chemical classes are shown in Table 1. However, only less than 100 have been addressed either in quantitative occurrence or toxicity studies. The DBPs that

This study has as main goal a consistent analysis of the major problems caused by emerging DBPs to drinking water supplies. It presents a comprehensive review of the research
The questions (Table 1) were broadly categorized to evaluate a) experience with IHC-based TCR assessment from 2008 to 2018, b) use of alternative methods for targeted
- Is halogenated pyrrole a drinking water DBP?
- In 2003, a new halogenated pyrrole – 2,3,5-tribromopyrrole (structure in Table 1) – was identified in drinking water . This represents the first time that a halogenated pyrrole has been observed as a drinking water DBP for any disinfectant.
- What is the LOQ of DBP in water?
- LOQs of DBPs in water ranged between 0.1 µg/L (THMs, HANs, HKs, trichloronitromethane) and 10 µg/L (chlorate, chlorite), and LODs of HAAs in urine were in the range between 0.02 µg/L (TCAA) and 3.98 µg/L (iodoacetic acid) (Table S1). Drinking water samples were analyzed for 11 HAAs, 4 THMs, 4 HANs, 2 HKs, TCNM, chlorate and chlorite.
- Can derivatizing agents identify polar carbonyl DBPs in drinking water?
- American Chemical Society, Washington DC, pp 356–375 Richardson SD, Karst U (2001) A new tailor-made derivatizing agent for identifying polar carbonyl DBPs in drinking water. In: Proceedings of the American Chemical Society conference.
- What are emerging pollutants (DBPs)?
- Most DBPs could be defined as emerging pollutants (EPs) (see Table 1), according to the Norman Network classification (Norman Network, 2016). EPs are chemical compounds with risks to human health, which appear in drinking water as a consequence of disinfection treatment (Table 1).
- How to predict non-regulated DBP?
- Statistical models were developed based on THMs as explanatory variables using multivariate linear regression and machine learning techniques to predict non-regulated DBPs. Chlorate, THMs, HAAs, and HANs were quantified in 98–100% tap water samples with median concentration of 214, 42, 18, and 3.2 μg/L, respectively.
- What is a DBP in water chemistry?
- Usually, DBPs are related to the use of chlorine-based disinfectants (chlorine gas, chloramines, chlorine dioxide, hypochlorite/hypochlorous acid) or ozone and to the raw water physicochemical features. The most common DBPs classes, their sources and health effects are presented in Table 1.
