Article Synopsis
- Regulations use THM4 and HAA5 to measure health risks from disinfection byproducts (DBPs), assuming these metrics reflect toxicity levels.
- A study found that while increasing chlorine contact time raised THM4 and HAA5 levels, it actually decreased overall cytotoxicity, suggesting these metrics may mislead regulatory focus.
- Alternative methods, like granular activated carbon followed by chlorine, were shown to significantly reduce cytotoxicity, indicating the need for better toxicity-correlating metrics to enhance consumer safety in water distribution systems.
Granular activated carbon treatment with postchlorination (GAC/Cl) and chlorination followed by chloramination (Cl/NHCl) represent two options for utilities to reduce DBP formation in drinking water. To compare the total cytotoxicity of waters treated by a pilot-scale GAC treatment system with postchlorination (and in some instances with prechlorination upstream of GAC (i.e.

However, studies on the fate and transfer of BDE-47 in the aquatic food chain remain scarce. In this study, we investigated the bioaccumulation and elimination of BDE-47 in Chlorella pyrenoidosa, as well as the trophic transfer and biomagnification of BDE-47 in the "C.
