Abstract
This study aimed to investigate the emission and multimedia fate as well as potential risks of triclosan TCS in all of 58 basins in China The results showed that the total usage of TCS in whole China was 100 t/year and the discharge to the receiving environment was estimated to be 661 t/year The predicted TCS concentrations by the level III fugacity model were within an order of magnitude of the reported measured concentrations TCS 908 was discharged into the water compartment and 92 to the soil compartment The TCS concentration levels in east China were found generally higher than in west China In addition the input flux for TCS to seawater was largely attributed to the seasonal variations in advection flows Preliminary risk assessment showed that medium to high ecological risks for TCS would be expected in the eastern part of China due to the high population densityThe authors would like to acknowledge the financial support from the National Science Foundation of China NFSC 41473105 NSFC U1133005 and National Water Pollution Control Programme 2013ZX07211006 Thanks go to BG Li at the Peking University for his assistance in modelling Thanks also to two anonymous reviewers for their comments and suggestions This is a Contribution No 2037 from GIG CAS
