The adsorption and reduction characteristics of Hg2+ by a green alga, Chlorella sp. were investigated in the presence of Cl- Volatilization of mercury was greatly affected by the concentration of Cl- and rapid volatilization was observed at Cl- concentration at which [HgCl2] 0 complex was dominant. Toxicity of Hg2+ to Chlorella cells was also enhanced under the same conditions. Although the amount of Hg2+ adsorbed on the surface of the cells decreased with increasing Cl- concentration, the amount of Hg2+ taken up into the cells increased with increasing distribution ratio of [HgCl2] 0 complex in the system. These results indicate that the formation of [HgCl2] 0 complex facilitated the uptake of Hg2+ into Chlorella cells, and hence, the rate of Hg2+ reduction under light irradiated conditions and the toxicity of Hg2+ to the cells were greatly enhanced.
