Abstract

 Triclosan (TCS) and Trichlorocarban (TCC) are widely used as antibacterial agent in liquid toothpaste, soap, shampoo, cosmetics and so on. In this study, we evaluated potential biological effects of TCS and TCC on mysid (Americamysis bahia). Survival and growth test was performed from a procedure of the USEPA. The 96h-LC50 values were 70 µg/L in TCS, and 12 µg/L in TCC, respectively. The growth and maturity examination demonstrated significant reduction in each measurement item at extremely lower concentrations than LC50 levels of TCS and TCC. The results of this study indicate that subchronic exposures to TCS and TCC affect growth and reproductive fitness of mysid.
