Abstract

Triclosan is widely used in personal care products, and has been reported to be toxic to aquatic organisms. The purpose of this study was to determine the triclosan levels in influents and effluents from three different sizes of sewage treatment plants using chlorine and ultraviolet (UV) for disinfection (i.e., STPs A, B, and C). Variations of triclosan concentration in influents and effluents (i.e., 9:00 a.m., 11:00 a.m., 13:00 p.m. and 15:00 p.m.) were also observed, respectively. The influent and effluent samples of the three STPs were composite samples collected every 2h during 9:00 a.m.-3:00 p.m by manual grab method, respectively. The samples were analyzed using a solid phase extraction (SPE) procedure, followed by liquid chromatography with tandem mass spectrometry (LC-MS-MS). Results demonstrated all of influent and effluent samples from three STPs contained triclosan. Significantly higher levels of triclosan were observed in effluent samples collected at STPs A (Median: 27.0 ng/L) as compared to in those collected at STPs B (15.0 ng/L), and C (8.0 ng/L) (p=0.012). STP A had the most serviced inhabitants and sewage flow. The triclosan levels at STP C with UV disinfection were lowest. The daytime peak of triclosan concentration in the collected influent samples was seen around 9:00 a.m. Notably, sewage discharge is the contamination source of triclosan in water bodies. Moreover, sewage flow and methods of disinfection may be the factors that affect the concentration of triclosan in effluents from sewage treatment plants.
