文摘
- •
Biotic Hg methylation occur in mangroves but which microorganisms are involved?
- •
Inhibition of sulfate-reducing bacteria and prokaryotes reduced MeHg formation and SRR.
- •
Inhibition of methanogens either reduced or increased methylation in different sites.
- •
Iron amendment stimulated Hg methylation in low and inhibited in high concentrations.
- •
SRB are important Hg methylators but other groups (IRB, methanogens) may be involved.
