对含铊黄铁矿利用工厂周边大气气溶胶(PM10和PM2.5)中铊的含量分布进行了分析研究,同时运用富集因子法探讨气溶胶中铊的来源.结果表明,硫酸厂周边大气气溶胶PM10和PM2.5中铊的污染程度比较严重,其日浓度分别为1.28~6.92ng·m-3和1.27—4.29ng·m-3.PM10和PM2.5中铊的富集因子均大于10,是典型的污染元素,其中PM10中铊的主要污染来源贡献为硫铁矿焙烧渣搬运过程中的细颗粒扬尘,而PM2.5中铊的主要污染来源贡献为硫酸生产排放的尾气.
對含鉈黃鐵礦利用工廠週邊大氣氣溶膠(PM10和PM2.5)中鉈的含量分佈進行瞭分析研究,同時運用富集因子法探討氣溶膠中鉈的來源.結果錶明,硫痠廠週邊大氣氣溶膠PM10和PM2.5中鉈的汙染程度比較嚴重,其日濃度分彆為1.28~6.92ng·m-3和1.27—4.29ng·m-3.PM10和PM2.5中鉈的富集因子均大于10,是典型的汙染元素,其中PM10中鉈的主要汙染來源貢獻為硫鐵礦焙燒渣搬運過程中的細顆粒颺塵,而PM2.5中鉈的主要汙染來源貢獻為硫痠生產排放的尾氣.

PM10 and PM2.5 aerosols samples were collected around a factory making use of pyrite containing thal- lium in the west of Guangdong Province. Total concentrations of thallium in PM10 and PM2.5 were quantified by acid digestion method. The pollution level of thallium and its origins in PM10 and PM2.5 were evaluated and dis- cussed in this paper. Results showed that thallium concentrations in PM10 and PM2.5 were significantly high around the sulfuric acid factory, which were in the range of 1.28 -6.92 and 1.27 -4.29 ng · m-3, respectively. High enrichment factor values (K 〉 10) were obtained for thallium in PM10 and PM2.5 , reflecting the importance of anthropogenic inputs. The major anthropogenic input of thallium in PM10 was from the raise dust yielding from pyrite roasting cinder transportation, while thallium in PM2.5 was from the exhaust emissions of sulfate production.
