Effect of triclosan exposure on mortality and behavioral changes of Poecilia reticulata and Danio rerio

Triclosan (TCS), a chemical used for its antibacterial properties, is an ingredient in many detergents, soaps, deodorants, cosmetics, antimicrobial creams, toothpastes, and an additive in various plastics and textiles. The behavioral changes at different TCS concentrations (0.001-0.002-0.005-0.01-0....

Description
Summary:Triclosan (TCS), a chemical used for its antibacterial properties, is an ingredient in many detergents, soaps, deodorants, cosmetics, antimicrobial creams, toothpastes, and an additive in various plastics and textiles. The behavioral changes at different TCS concentrations (0.001-0.002-0.005-0.01-0.02-0.05-0.1-0.2-0.5 mg/L) were determined for the each test organisms in the study. The synthetic freshwater has temperature 20 ± 2°C, dissolved oxygen 7.0 ± 2 mg/L, pH 7.0-8.0. All experiments were replicated three times, in 14 h light, 10 h dark incubations, 10 fishes were put to each aquarium. In hourly and daily observations, times of dead and number for Poecilia reticulata, Danio rerio were recorded. Behavioral changes of Poecilia reticulata and Danio rerio were observed, such as fast-moving, uncontrolled swimming, trying to escape out of the water, vertical action to the water surface, loss of balance, respiratory difficulties, chills, and inversion.
