锑为非生物体必须元素,对生物和人体有慢性毒性[1],锑以各种化合物形式或溶解态存在于水环境中,主要价态为Sb3+和Sb5+[2]。受人为排放、岩石风化和雨水冲刷等因素影响,水体成为大部分锑元素的环境归宿[3]。汞是一种蓄积性有毒元素,在体内达到一定量时,将对人的神经系统、肾、肝脏产生严重的损害[4]。伴随着工业的发展,汞的用途越来越广,生产量急剧增加,从而造成水体汞污染,排向大气和土壤
Antimony is an essential element of non-living organisms and has chronic toxicity to organisms and humans [1]. Antimony is present in aqueous environments in various chemical forms or in dissolved form. The main valence states are Sb3 + and Sb5 + [2]. Affected by anthropogenic emissions, rock weathering and rainfall erosion, water bodies have become the environmental fate of most antimony elements [3]. Mercury is an accumulative and toxic element that, when it reaches a certain amount in the body, will cause serious damage to the nervous system, kidney, and liver of humans [4]. With the development of industry, the use of mercury is more and more widely used, and the output of mercury is drastically increased, causing the mercury pollution of water bodies to the atmosphere and the soil
