THEOPHRASTOS: PMx EMISSION FACTORS - DISPERSION FROM FUGITIVE DUST SOURCES IN LIGNITE MINES OF WESTERN MACEDONIA, GREECE

摘要

According to the Regulation 166/2006 of the European Parliament, mining enterprises are obliged to quantify the pollutants emissions from their fugitive sources in order for an integrated, publicly accessible pollutant-release and transfer register to be established at the European Community level. Western Macedonia comprises a Greek region where intensive industrial activities are present, mainly in the electricity production sector. Four open lignite mines feed the five lignite power plants operating in the area, thus contributing to the atmospheric pollution of the region. For the quantification of fugitive emissions, emission factors are required as input data in dispersion simulation tools which are used in integrated systems for environmental management and decision making. A review of bibliographical sources indicates only a limited availability of such factors, mainly corresponding to open pit mines in Canada, India and the U.S.A., that are not representative for all mining operations. The determination of PMx emission factors for fugitive emission sources of the lignite mines operating in Western Macedonia, as well as the study of PM dispersion from such sources is the subject of the project THEOPHRASTOS, which is presented in this paper. The scarcity of literature on validated experimental data on emission factors points to the necessity of field campaigns and combined modelling approaches for assessing fugitive PM emissions from mining operation.
