Detection of triclosan and its metabolites in Central Virginia wastewater

CHED 826

Kimberly Anne Wilson and David R. Orvos.
Pharmaceutical and other personal-care products (surfactants, antibiotics, and antimicrobial agents), collectively known as PPCPs, are not mandated under the U.S. Clean Water Act for removal from wastewater. Triclosan (5-chloro-2(2,4-dichlorophenoxy)phenol) or (IrgasanŽ DP 300) is an antimicrobial agent typically used in personal care products such as toothpastes, soaps, shampoos, and deodorants. This study was conducted to determine the concentration of triclosan and the presence of any of its metabolites in Amherst County, Virginia wastewater using HPLC and GC/MS. The wastewater samples were also used to identify triclosan-resistant strains of microorganisms.
