The HgT concentration of fly ash in China was relatively
smaller than those in two districts above. It is noting that
the concentration of HgT in 7 fly ash samples were higher than
10 mg kg1, and most of these samples were collected from the
MSWI plants in eastern China. As fast economic growth in eastern
China, this is contributed to the more consuming of Hg-containing
commercial product in developed cities than the other part of
China.
