| Abstract: | 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. |
