Objective To understand the impacts of a small antimony smeltery on surrounding environment. Methods The samples of raw materials,such as ore and coal,soil and plant around a small antimony smeltery in southwest Guizhou province were analyzed. Results The levels of arsenic,mercury,fluoride ,antimony and selenium in soil around the antimony smeltery significantly increased compared with the average background levels of related elements in nationwide range . The levels of arsenic, mercury,fluoride ,antimony and selenium in soil around the antimony smeltery were 1. 73～4.69,4. 75～237.5,2. 26～3.42,35.6～36. 2,54. 29～57.14 times as much as their related average levels in our country respectively. The levels of arsenic ,mercury ,fluoride and selenium in soil around the smeltery were 1.25～ 3. , 58,1.86～ 93.14,1.38～ 2.08,33. 04～ 34.78 times as much as their related average levels of Guizhou province respectively. The levels of arsenic, mercury, fluoride, antimony and selenium in corn leaves around the smeltery was 67,26.7,1046.4,2220,38. 8 times as much as their related average levels in non-polluted plants respectively. Conclusion The air pollutants,such as sulphur,arsenic,mercury,fluoride,antimony and selenium in industrial waste gas emitted from the antimony smeltery had resulted in heavy pollution to the environment, which was aggravated by the application of coal with high level of sulphur.
