某氟化学工业园对当地食物及环境的影响

Investigation of Environmental Pollution around Fluoride Chemical Industrial Park

目的了解某氟化工业园对周边环境造成的污染。方法于2007年5月至2009年3月期间,选择某氟化工业园所在地周边4 km范围内的7个村及一对照地区,对两地空气、土壤、水、食物(大米、蔬菜)中氟含量进行比较。结果暴露区蔬菜和淡水鱼类氟含量过标准限值,且土壤、河水、蔬菜中氟含量高于对照区,差异有统计学意义(P<0.05),并且大米氟含量与距污染源距离呈负相关(r=-0.364,P=0.032)。结论本次调查地区存在氟化学工业园对当地周边地区造成氟污染的可能。

Objective To understand the environmental pollution level around the fluoride industrial park. Methods A fluoride industrial park and a control area were selected, and the fluoride content of the air, soil, water and foods were compared. Results The mean fluoride content of vegetables and freshwater fish collected from the area around the fluoride industrial park were more than the standard limits, and the fluoride content of the soil, water, vegetables between the two investigated areas had significant differences. Fluorine content of rice was linearly correlated with the distance （r=-0.364,P= 0.032）. Conclusion Fluoride industrial park may have caused environmental fluoride pollution in the investigated area.
