电解铝厂周边土壤和农作物氟污染评价

Assessment on Fluoride Pollution in Aoil and Crop Around Electrolytic Aluminum Factory

通过对广西某电解铝厂周边大气、土壤和农作物氟化物污染进行监测评价,结果表明:铝厂周围大气氟污染与采样点到铝厂距离无明显相关,却与采样点的方位成显著相关;土壤中水溶氟的含量与采样点到铝厂距离呈负相关。农作物玉米叶片氟污染物主要来自于铝厂排放的氟化物。玉米果实样品中的氟含量除对照点属于中度污染外,其余样点样品均属重污染。

Fluoride pollution in air, soil and crop around a electrolytic aluminum factory in Guangxi province has been monitored and assessed. The results indicated that fluoride pollution in air was not significantly related to the distance between the sampling plots and the aluminum factory, but was significantly related to the direction of the sampling plot; the content of water-soluble fluoride in soil was negatively related to the distance between the sampling plots and the factory. The fluoride in the mealie leaves mainly came from the emission of the aluminum factory, and the pollution level of fluoride in mealie fruitS was middle-polluted in the controlling plot, but were heavy-polluted in the rest plots.
