【 摘 要 】

According to The European Parliament and The Council (Decision No. 1386/2013/UE), the emission of air pollutants during the last years has decreased, but still constitute a serious problem in many parts of Europe. Apart from sulfur oxide, nitrogen oxide and volatile organic compounds (VOCs), among air pollutants are also elements, which have a negative impact on environment and human health and life. During coal combustion and coking coal processes, a part of these elements are released into the atmosphere. For this reason, coal processing is one of the main sources of their emissions to the environment. Particular attention should be paid to the emission of such elements as mercury (Hg), arsenic (As), thallium (Tl) and their compounds, which are characterized by very high ecotoxicity. In this article the current standards and regulations on emissions of mercury, arsenic and thallium into the atmosphere for selected coal conversion processes as well as opportunities to reduce these emissions were presented.
