Disinfection by-products in drinking water
Chlorine is the most commonly used drinking water disinfectant. It has been used to disinfect water and make it suitable for drinking for more than 100 years. Some studies have suggested that long-term exposure to consistent high levels of THMs and/or HAAs might increase the risk of cancer.

Inhalation is reported to be a more significant route of exposure for swimmers, while exposure via dermal absorption is more important for hot tub users due to higher water temperatures. Health Canada conducted a national survey of DBP levels in treatment plants and distribution systems in 1993. A more recent analysis of data from 1990 to 2004
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
Disinfection Byproducts (DBPs) in Water: What You Need to
Different disinfection byproducts have their own harmful health effects. The most common disinfection byproducts, and their health effects, are: Bromate: vomiting, nausea, diarrhea, abdominal pain, hearing loss, kidney effects, nervous system effects. Chlorate: potential carcinogen, limits the blood’s ability to absorb oxygen, leading to
- What are disinfection by-products (DBPs)?
- Disinfection by-products (DBPs) are chemicals that form when chlorine is used for disinfecting drinking water to prevent disease. The chlorine reacts with decaying organic matter, like leaves or vegetation, from lakes and rivers to form DBPs.
- What is a DBP in drinking water?
- DBPs are present in most drinking water supplies that have been subject to chlorination, chloramination, ozonation, or treatment with chlorine dioxide.
- How do DBPs form?
- Unlike most other drinking water contaminants, DBPs form from disinfectant application within the plant, as a result of the final drinking water treatment process (disinfection) and continue to form throughout the distribution system, such that control strategies necessarily focus on minimizing their formation.

- What types of DBPs are found in chlorinated drinking water?
- Two of the most common types of DBPs found in chlorinated drinking water are trihalomethanes (THMs) and haloacetic acids (HAAs). The use of chlorine to treat drinking water has almost completely eliminated waterborne bacteria and diseases like typhoid fever, cholera, dysentery and other gastrointestinal diseases.
- Can pharmaceuticals be converted to DBPs?
- However, because pharmaceuticals and personal care products typically are microconstituents in water supplies (generally <1 μg/L), even their conversion to DBPs at high yield is unlikely to make significant inroads into the uncharacterized TOX.
