Disinfection By-products (DBPs) How People Are Exposed to DBPs
containing DBPs. The skin also absorbs DBPs during bathing and swimming. After exposure, DBPs remain in the body for only a short period of time. How DBPs Affect People’s Health . The human health effects from DBPs at low environmental exposures are unknown. Humans exposed to unusually large amounts of some DBPs could experience liver damage
Disinfection By-products (DBPs) Factsheet | National
Disinfection by-products (DBPs) are formed when disinfectants like chlorine interact with natural organic materials in water, such as in chlorinated drinking water and chlorine-treated swimming pools. DBPs can be found in the air during activities such as showering, bathing, dishwashing, and swimming.

Waterworks-specific composition of drinking water
Reactions between chemical disinfectants and natural organic matter (NOM) upon drinking water treatment result in formation of potentially harmful disinfection by-products (DBPs). The diversity of DBPs formed is high and a large portion remains unknown. Previous studies have shown that non-volatile DBPs are
Drinking Water Disinfection Byproducts (DBPs) and Human
While drinking water disinfection has effectively prevented waterborne diseases, an unintended consequence is the generation of disinfection byproducts (DBPs). Epidemiological studies have consistently observed an association between consumption of chlorinated drinking water with an increased risk of bladder cancer. Out of the >600 DBPs identified, regulations focus on a few classes, such as
- What are disinfection by-products (DBPs)?
- Disinfection by-products (DBPs) are organic and inorganic compounds resulting from chemical reactions between organic and inorganic substances such as contaminates and chemical treatment disinfection agents, respectively, in water during water disinfection processes.
- Are disinfection byproducts toxic?
- Disinfection byproducts (DBPs) formed during the disinfection of water have drawn significant public concern owing to their diverse toxicities. In this study, a database of 6310 DBPs reported since 1974 was constructed.
- What percentage of DBPs are verified by chemical standards?
- Only 10% of reported DBPs are verified by chemical standards. Acids are the largest category among all functional groups of reported DBPs. Structures of proposed DBPs were characterized based on adjusted indexes. Since trihalomethanes were discovered in 1974, disinfection by-products (DBPs) in drinking water have attracted extensive attention.
- Are trihalomethanes a disinfection by-product?
- Since trihalomethanes were discovered in 1974, disinfection by-products (DBPs) in drinking water have attracted extensive attention. In 2011, more than 600 known DBPs were compiled; however, newly reported DBPs have not been integrated.
- What percentage of DBPs are found in real water?
- The results showed that the proportion of DBPs verified by standard compounds and frequently detected in real water is less than 7.0%, and most of DBPs remained to be identified. Approximately 88% of DBPs contain halogens, and brominated -DBPs occupied a similar ratio to chlorinated -DBPs in real water.
- How to remove DBP from water?
- AOPs and adsorption found as the best approaches of DBPs removal from the water. Disinfection means the killing of pathogenic organisms (e.g. bacteria and its spores, viruses, protozoa and their cysts, worms, and larvae) present in water to make it potable for other domestic works.
