摘要: There are few measures that can be used to distinguish among mixtures of disinfection by-products (DBPs) produced in the chlorination or chloramination drinking water. Objective similarities DBP would greatly simplify judgments about risk may associated with exposure DBPs a given water supply. Major chlorination/chloramination include trihalomethanes (THMs) and haloacetic acids (HAAs), which routinely measured for compliance regulations. A key question is whether measurement similar amounts these indicative myriad other known produced. This article utilized data from survey 35 utilities United States included several additional parameters, including members haloacetonitrile, trihaloacetaldehyde, halopropanone classes. Based upon distribution bromine THM class, concentrations unmeasured brominated bromochlorinated compounds could determin...
