Disinfection byproducts (DBPs) can be formed from many different kinds of carbon- and nitrogen-based organic materials. This study investigated DBP formation in the presence of two types of polybrominated diphenyl ethers (PBDEs), 2,2′,4,4′-tetrabromodiphenyl ether (BDE 47) and 2,2′,3,3′,4,4′,5,5′,6,6′-decabromodiphenyl ether (BDE 209). The effects of PBDEs on the formation of DBPs upon the chlorination (or chloramination) of Suwannee River humic acid (SRHA) were also evaluated. Results indicated that the chlorination of BDE 47 and BDE 209 resulted in the formation of DBPs, with 1,1,1-trichloro-2-propanone (1,1,1-TCP) being the major DBP type formed. When PBDEs were present in the SRHA solution, a lower amount of CHCl3 was formed, and more 1,1,1-TCP was produced. However, the effects of PBDEs on the formation of DBPs in the real surface water were insignificant because of the complicated water chemistry.
