环境锰污染对生物健康的威胁

Threat of environmental manganese pollution to biological health

锰广泛存在于自然环境中,是地壳最丰富金属元素之一,也是人类和其他生物正常生长、发育及维持细胞内环境稳定所必需微量元素。近年来,随锰广泛应用,环境锰含量超标,生物甚至人类摄入过量,导致锰中毒,受到人们关注。为此,文章探讨锰应用对土壤、水、空气、畜禽饲料、食品造成的污染,论述锰污染对生物甚至人类健康的威胁,以期为锰减排、污染治理、环境保护、生物和人类锰中毒防治及开展锰中毒机理研究提供参考。

Manganese(Mn)widely exists in natural environment,and is one of the most abundant metal elements in the earth's crust.It is also an essential trace element for normal growth,development,and maintenance in the stability of intracellular environment in organisms.However,in recent years,with the wide application of Mn,Mn contents in the environment is exceeded leading to Mn poisoning and bringing potential threat to the health of organisms and even humans.Therefore,this review discussed the pollution caused by Mn application to soil,water,air,livestock,poultry feed and food.In addition,the harm of Mn pollution to organisms and even humans was discussed in order to provide basis and references for the reduction of Mn emission,the treatment of Mn pollution,the protection of environment,the prevention and cure of Mn poisoning in humans and other organisms,and the researches on the mechanism of Mn poisoning.
