Disinfection by-products (DBPs) result from chemical reactions between organic and inorganic matter in water with chemical treatment agents during the water disinfection process. [1] DBPs are present in most drinking water supplies that have been subject to chlorination, chloramination, ozonation, or treatment with chlorine dioxide. Many hundreds of DBPs exist in treated drinking water and at least 600 have been identified. [2] However, only a handful of DBPs are actually monitored. Increasingly it is recognized that the genotoxicities and cytotoxicities of many of the DBPs not subject to regulatory monitoring, (particularly iodinated, nitrogenous DBPs) are comparatively much higher than those DBPs commonly monitored in the developed world (Trihalomethanes THMs and Haloacetic acids HAAs). A handful of studies have also shown a possible link between high levels of DBPs in water and adverse effects on reproductive health, including bladder cancer, low birth weight and miscarriage. The United States Environmental Protection Agency (USEPA) has set Maximum Contaminant Levels (MCLs) for bromate, chlorite, haloacetic acids and total trihalomethanes (TTHMs). The World Health Organization (WHO) has established guidelines for several DBPs, including bromate, bromodichloromethane, chlorate, chlorite, chloroacetic acid, chloroform, cyanogen chloride, dibromoacetonitrile, dibromochloromethane, dichloroacetic acid, dichloroacetonitrile, NDMA, and trichloroacetic acid.
As a global leading DBPs testing company, Alfa Chemistry provides incredible services and credible results. Alfa Chemistry is your one-stop-shop laboratory to test DBPs in water according to EPA methods.
