CONTAMINATION OF TRICLOSAN IN FISH TISSUES COLLECTED FROM SAVANNAH, GEORGIA, USA
Triclosan (TCS) is a common antibacterial chemical currently in widespread use in household, health care products in various consumer and personal care products. Earlier research has revealed considerable levels of these antibacterial agents in wastewater, river water, aquatic wildlife and humans. TCS are reported to be toxic and produce adverse health effects to wildlife and humans. Furthermore, TCS undergo photo-degradation and modified into lower chlorinated dioxins and phenols. During treatment process in wastewater treatment plants TCS also shown to convert into methyl triclosan (MeTCS) which is more stable. Consequently, in this study we measured TCS in selected fish species collected from various aquatic ecosystems in Savannah, Georgia USA. Concentrations of TCS in liver and muscle were in between 0.9-5.6 and 0.3-2.7 ng/g dry weight, respectively. Catfish collected from Lake Mayer contained maximum concentrations than other fish species collected from rivers, ponds, open oceans and estuarine ecosystem in Savannah. Observed concentrations were comparable to available literature despite meager study available so far.
