摘要

Methyl mercury (CH3Hg+),a neurotoxin,is the most toxic form of mercury that occurs in natural waters [1-4].It is a cause of concern because of increasing worldwide pollution by mercury in both water and atmosphere [3,5].Photodegradation of CH3Hg+ is one of the main removal pathways from surface waters,and it has been shown to occur in the presence of dissolved organic matter (DOM)but not in ultra-pure water [2,4].
