In India, coal utilization in power generation, constitutes as the single largest source of mercury emissions. This study presents mercury content in Indian sub-bituminous and bituminous coals that are primarily used as fuel in large-scale electricity generation facilities. A total of 165 number of coal samples have been collected from the major coal producing regions of the country. Along with the mercury content, other chemical parameters like moisture, ash, volatile matter, total Sulphur and gross calorific value were also analyzed. Mercury concentrations of these coals were found to be between 3 and 554 µg/kg, with an average of 175 µg/kg. Variation of the mercury content with the rank parameters like volatile matter, carbon content, ash and total Sulphur were also assessed. No significant correlations were observed with the rank parameters but a general trend of increasing mercury with ash content is discernible.

在印度，煤炭在发电中的利用是最大的汞排放源。这项研究提出了印度亚烟煤和烟煤中的汞含量，这些煤主要用作大型发电设施的燃料。从该国主要产煤地区收集了总共165个煤样品。除汞含量外，还分析了其他化学参数，例如水分，灰分，挥发性物质，总硫和总热值。发现这些煤中的汞浓度为3至554 µg / kg，平均为175 µg / kg。还评估了汞含量随挥发性物质，碳含量，灰分和总硫等等级参数的变化。
