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

1. Introduction Implementation of drinking water disinfection and filtration effectively reduced pathogen-related waterborne diseases, such as typhoid fever and cholera, and therefore can be regarded as one of the most important public health advances of the last century. 1–3 However, the discovery of disinfection by-products (DBPs) 4 —formed by the reaction between chemical disinfectants
Overview of Disinfection By-products and Associated Health
Future research should develop methods to evaluate the effects of the DBP mixture and the interaction with personal characteristics (e.g., genetics, lifestyle), clarify the association between swimming pools and respiratory health, evaluate the occurrence of DBPs in low- and middle-income countries, and evaluate outcomes suggested by animal

Efficient disinfection mustnever be compromised.” Thu s, waterborne pathogens pose a real and immediate threat to health; water disinfection byproducts are certainly the lesser of these two evils. USEPA Standards for DBPs The disinfectant / disinfection by-products (D/DBP) rule that regulates DBPs in the United States was
- 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 toxic DBPs formed during water treatment?
- The formation of toxic DBPs during water treatment has been comprehensively documented over the last five decades. However, the detailed mechanisms behind the formation of individual DBP compounds, the identification of emerging DBP categories, and the properties of their precursors remain critical topics of investigation.
- Which disinfection byproducts are more toxic than C-DBPs?
- On the other hand, N-DBPs, which include haloacetonitriles (HANs), halonitromethanes (HNMs), haloacetamides (HAcAms), and nitrosamines (NAs), are generally more toxic than C-DBPs . Nitrogenous disinfection byproducts (N-DBPs) and iodinated disinfection byproducts (I-DBPs) are becoming increasingly concerning in water treatment.
- Are harmful disinfection byproducts in water treatment safe?
- Growing concerns over public health and environmental safety have intensified the focus on minimizing harmful disinfection byproducts (DBPs) in water treatment. Traditional methods like chlorination, while effective against pathogens, often lead to the formation of DBPs, which pose significant risks.
