Methyl mercury Inorganic mercury in waste water is absorbed by particulate matter and settle to the bottom of the water body, then methylated by the microbic transferase. Methyl mercury can also combine with Cl - or OH - and generate methyl mercuric chloride ( 氯化甲基汞 ) or methyl mercuric hydroxide ( 氢氧化甲基汞 ) neutral or acid conditions, methyl mercuric chloride is dominant pH=8, [Cl - ]
Dimethyl mercury Under anaerobic conditions, undersaturated methyl metals are completely methylated. p303
