Antimony (Sb) has received increasing attention recently due to its toxicity and potential human carcinogenicity. In the present work, drinking water, fish and algae samples were collected from the Xikuangshan (XKS) Sb mine area in Hunan, China. Results show that serious Sb and moderate arsenic (As) contamination is present in the aquatic environment. The average Sb concentrations in water and fish were 53.6 + or - 46.7 microg L(-1) and 218 + or - 113 microg kg(-1) dry weight, respectively. The Sb concentration in drinking water exceeded both Chinese and WHO drinking water guidelines by 13 and 3 times, respectively. Antimony and As concentrations in water varied with seasons. Fish gills exhibited the highest Sb concentrations but the extent of accumulation varied with habitat. Antimony enrichment in fish was significantly lower than that of As and Hg.
由于锑的毒性及其对人类的潜在致癌性，近年来受到越来越多的关注。本研究采集了中国湖南锡矿山锑矿区的饮用水、鱼类和藻类样本。结果表明，该水域环境受到严重的锑和中等程度的砷污染。水和鱼中的锑浓度平均值分别为 53.6±46.7μg/L 和 218±113μg/kg 干重。饮用水中的锑浓度分别超过中国和世界卫生组织饮用水标准 13 倍和 3 倍。水中的锑和砷浓度随季节而变化。鱼鳃的锑浓度最高，但积累程度因栖息地而异。鱼类对锑的富集程度明显低于砷和汞。
