摘要
通过测定广西某电解铝厂周边大气、土壤和农作物中氟化物含量,对该厂周边的氟化物污染进行了评价,结果表明:电解铝厂周围大气氟污染与采样点的方位成显著相关关系;农作物玉米叶片氟污染主要来自于电解铝厂无组织排放的氟化物,而土壤中总氟含量除受大气中氟化物的影响外,还与当地的地质构造、土壤类型等因素有关,与主导风向无明显的相关关系,土壤中水溶氟含量与采样点到电解铝厂距离呈负相关。
Based on the determination of fluoride content in the atmosphere,soils and crops around a certain electrolysis aluminum plant in Guangxi and assessment on fluoride pollution around the plant,the result shows that the orientation between the fluoride pollution of atmosphere around the electrolysis aluminum plant and sampling spot shows outstanding correlativity;the fluoride pollution of crop corn lamina mainly comes from in-organization emission fluoride of electrolysis plant,the total fluoride content in soil is not only affected by fluoride in the atmosphere,but also is related to local geological structure and type of soils,and the leading wind direction shows no obvious correlativity,the distance from water-soluble fluoride content in the soil and sampling spot to the aluminum plant assumes negative correlativity.
