<strong>Mercury</strong> in the soil<br />
• Over 95% of the mercury entering the soil can be<br />
retented or fixed by soil. Clay minerals and<br />
organic matter in the soil have strong absorption<br />
toward mercury. Thus, mercury accumulates<br />
easily in the surface of soil.<br />
• Amicrobic transformation:2Hg + = Hg 2+ + Hg o<br />
• Microbic :HgS(thiobacillus 硫 杆 菌 )→ Hg 2+ (antimercury<br />
bacteria 抗 汞 菌 )→ Hg 0<br />
• Methylation of mercury (See Bioconversion of<br />
Pollutants)
