BIOSIS COPYRIGHT: BIOL ABS. Accumulation of As, Se, Cr, U, Th etc elements is 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 the environment. It is obvious that in order to study the relationship between coal burning and environmental pollution, it is necessary for us to thoroughly investigate trace elements in coal. This paper reports As, Se, Cr, U, Th contents in coal samples from 110 coal mines in 24 provinces and cites of China, determined by using instrumental neutron activation analysis. 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.
