Correlation analysis between typical metal elements and PM2.5 in a uranium tail mining area in East China.

The relationship between PM_2.5 concentration and typical metal elements around a uranium deposit in eastern China was analyzed. The correlation between PM_2.5 concentration and metal content in PM_2.5 is generally poor, while the correlation between metal elements is generally good. The analysis shows that PM_2.5 concentration and U content show the same trend with seasonal replacement, and Th content has a positive correlation with PM_2.5 concentration on the whole. PM_2.5 concentration was positively correlated with the content of Pb, Cd and Al. There is no obvious relationship between PM_2.5 concentration and Ti content, and other theoretical explanations need to be studied. [ABSTRACT FROM AUTHOR]
