| Abstract: | This paper addresses the distribution and occurrence of harmful organic substances in coal gangue dump from Jiulong Coal Mine
and its influence on the environment. The samples were taken from the coal gangue dump and coal waste water stream and analyzed
by organic geochemical methods. The results indicate that the coal gangues contain abundant harmful organic substances like
polycyclic aromatic hydrocarbons. The TOC and sulfur contents of the samples are much higher than those of the background
sample except Sample JL7. The contents of organic bulk parameters are relatively high. Ten carcinogenic PAHs were identified
and these harmful organic substances have influenced the surrounding area. Along the waste water stream, organic substances
pollute at least 1,800 m far from the coal gangue dump. |
