Disinfection Byproducts (DBPs) | The Water Research Foundation
Disinfection Byproducts (DBPs) The use of strong oxidants to disinfect water has virtually eliminated waterborne diseases like typhoid, cholera, and dysentery in developed countries.
Disinfection By-products (DBPs) Factsheet | National
Disinfection By-products (DBPs) Factsheet. 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.
High-molecular-weight by-products of chlorine disinfection
High-resolution MS techniques have found >1,000 chlorinated DBP features (that is, distinct elemental formulae) in chlorine-treated drinking water supplies in China 93, 556 chlorinated DBP
Overview of Disinfection By-products and Associated Health
The presence of chemical compounds formed as disinfection by-products (DBPs) is widespread in developed countries, and virtually whole populations are exposed to these chemicals through ingestion, inhalation, or dermal absorption from drinking water and swimming pools.
Chemical and Biological Hazard Prevention Studies and
The public’s exposure to disinfection byproducts (DBP) in swimming pools is of growing concern globally. DBPs are the inevitable result of chemical reactions between the disinfection agents added to swimming pool water and the organic or nitrogeneous matter that is naturally present or introduced by bathers.
- 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.
- How are chlorinated disinfection byproducts (CL-DBPs) generated?
- Various chlorinated disinfection byproducts (Cl-DBPs) are generated via reactions with tannic acid during disinfection with chlorine. We used high-resolution mass spectrometry in combination with our self-developed halogen extraction code to selectively identify Cl-DBPs.
- Can chemical disinfection cause DBPs in drinking water?
- However, chemical disinfection can also generate disinfection byproducts (DBPs) as a side effect. To mitigate their risks, many countries and organizations have enacted regulations or guidelines to control DBPs in drinking water.
- 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.
- 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 disinfection by-products environmental contaminants?
