American researcher's latest find, the sea water fish which includes the mercury are more harmful to the human body than the fresh-water fishes including mercury. The researchers of Duke University of American say on new " nature - geoscience " magazine network edition, they find while measuring the mercury to fresh-water fishes and sea water fish, though the mercury density of methyl that the fresh-water fishes include is often higher than the sea water fish, but the former take less than the latter to danger that human body cause. Researchers explain, there are two reasons to cause this phenomenon: First, the mercury in the fresh water depends on the organic matter that can be dissolved, and the mercury in the sea water is permeated through the salt of the sea water, it is more difficult for the latter to degrade than the former; Second, the toxicity of the degradative mercury of sunshine, the organic matter in the fresh water is apter to accept the sunshine shines, so fresh water the intersection of mercury and toxicity in the organic object will reduce to some extent, and organic matter live a life dark and underwater in the sea water, not so apt to accept that shine, the toxicity of the mercury is difficult to degrade naturally. Researchers propose, government and scientific research institution should not merely pay close attention to fresh water fish and water silver to pollute, and should pay close attention to sea water fish and water silver is polluted. The mercury is that metal mercury is commonly called as, have toxicity, the serious mercurial poisoning will cause people's death, the mercury pollution of the long-term low dosage can cause the injury to the human nervous system.
