چکیده
Mercury in coals is one of the important sources atmospheric mercury, which potentially harmful to ecological environment. Based on data 970 coal samples, concentration, spatial distribution and occurrence mercury Chinese were analyzed. The main conclusions are as follows: concentration coalfields uneven; medium high mainly distributed southwest China eastern Inner Mongolia. concentrations various coal-forming periods K (0.320 mg/kg) > P2 (0.220 C3 (0.179 J (0.177 D (0.165 P1 (0.136 C1 (0.090 E (0.086 T3 (0.066 mg/kg). different ranks Lignite (0.164 mg/kg), long flame (0.078 non-caking (0.256 weakly caking gas (0.151 fat (0.122 coking (0.171 lean (0.393 meagre (0.161 anthracite (0.160 Sulfide bound state form coals, pyrite medium.

Three hundred and five coal samples were taken from the main coal mines of twenty-six provinces, autonomous regions, and municipalities of China. The method of pyrohydrolysis was applied to measure the fluorine content in the samples, which exhibit logarithmic normal frequency distributions. The range of fluorine content in dry coal varies from 25 to 1230 mg/ kg with a geometric mean of 136 mg/...
