Triclosan, an antibacterial agent, increases intracellular Zn2+ concentration in rat thymocytes: Its relation to oxidative stress

► Triclosan, an antibacterial agent, is an environmental pollutant. ► Triclosan increases intracellular Zn2+ and decreases thiols in rat thymocytes. ► Negative correlation is found between them. ► Triclosan potentiates the cytotoxicity of H2O2. ► Triclosan may induce oxidative stress that leads to intracellular Zn2+ release.
