| 英文摘要 |
| Accumulation of As, Se, Cr, U, Th etc dements in the environment is interrelated to emission of coal burning as these elements existing in coal are abundant and Coal consumes in bulk. So coal burning is considered as one of pollution sources in the area where some harmful trace elements entered into tphe environment. It is cbvious that in order to study the relationship between coal burning and environmental pollution, it is necessery for us to thoroughly investigate trace elements in coal. This paper reports As. Se, Cr, U, Th contests in coal samples from 110 coal mines in 24 provinces and cites of China, determined by using instrumental neutron activation anlysis. The content ranges of As, Se, Cr, U, Th in coal mines in China are given. The relationship between these elements and the environment has been discussed. |
