摘    要:工业生产排放和土壤氟高背景值导致我国部分地区氟污染严重,给生态安全和人类健康造成严重威胁.本文基于我国氟排放重点行业的生产产能,估算重点行业生产过程中氟排放量,构建我国重点行业氟排放清单,基于数据集成和融合,分析我国土壤氟背景值、氟地球化学分布和土壤氟浓度分布,并对氟污染典型区域氟污染成因及控制进行系统分析.分析发现,我国氟排放的重点行业有钢铁、磷肥和电解铝.磷肥施用的氟排放量最大,但施用面积大,浓度贡献小;电解铝行业的氟排放强度大;钢铁行业的氟排放总量大,但排放强度较小.我国大部分地区土壤氟背景值不高,环境容量大.但部分地区氟污染严重,主要是由工业氟排放和土壤氟高背景值造成,这些地区应采取相应的防控措施.

关 键 词:  电解铝  排放清单  土壤

Abstract:Industry-induced fluorine emissions and high background values of fluorine in soil lead to serious fluorine pollution in some regions of China, posing a serious threat to ecological security and human health. Based on the production capacity of China’s key industries contributing to fluorine emission, we estimated the fluorine emissions of key industries and built a fluorine emission list in China. Based on data integration and fusion, the soil fluorine background value, fluorine geochemical distribution and soil fluorine concentration distribution in China were analyzed. Then, the causes and control of fluorine pollution in typical areas were analyzed. The results showed that productions of steel, phosphorus fertilizers and electrolytic aluminum were the key industries for fluorine emissions in China. The highest fluorine emission was from the application of phosphorus fertilizers. Due to the huge area of P application, its contribution to soil fluorine concentration was negligible. Electrolytic aluminum production resulted in a high intensity of fluorine emission. A high amount of fluorine was discharged with steel industry production, with low emission intensity. In most parts of China, the soil fluorine background value is low and the environmental capacity is large. In some areas of China, however, fluorine pollution is serious, mainly due to industrial fluorine emissions and high background values of fluorine in soil. These regions should take corresponding prevention and control measures.
Keywords:fluorine  electrolytic aluminum  emission list  soil
