Abstract

Investigations so far conducted and reported in the different parts of the world on the geochemistry, nature, mode of occurrence and distribution of trace elements in coals and lignites have been reviewed in brief in this communication. In fact, of late, a growing consciousness of population in general on the danger of environmental pollution due to emission, discharge and distribution of otherwise reconginsed and identified toxic trace elements inclusive of radioactive and carcinogenic ones during utilization of coals in different phases and stages has led to a voluminous research and development activity throughout the world. This aspect has also been dealt in the communication. Cases of a few trace elements like germanium, gallium and yttrium which have growing industrial applications in the fields of electronics and computer techniques and which are comparatively rare on earth’s surface and whose of winning thought to be somewhat promising from coal and lignite resources have also been reviewed here. Status of information on research and development work on trace elements in Indian coals and lignites has been added. In fact, quantum of research activity in this context is comparatively less and there is a need for further investigation in our country.
