Description:
A 12-days photolysis experiment of triclosan, a widely used bactericide, was performed in freshwater and seawater under a low intensity artificial white light source. Photodegradation of triclosan was observed in both the freshwater and seawater samples. Assuming a first-order reaction, half-lives of triclosan in the freshwater and seawater were approximately 8 and 4 days, respectively. 2,8-Dichlorodibenzo-p-dioxin (DCDD) was detected in both the freshwater and seawater samples after 3 days of irradiation. The photodegradation of triclosan and the production of DCDD suggest that triclosan could be less stable and DCDD might be more stable in seawater than freshwater. As a result, DCDD produced from triclosan survives for a longer time in seawater.
