Description
Summary: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.
