Аннотация:The Orot Rabin power plant is a 2,590 MW coal-fired power plant located along the Mediterranean coast north of Tel Aviv.Close by to the east is the city of Hadera.Due to the predominant east-west wind patterns, both Hadera and the nearby communities may be impacted by stack emissions from the power plant.In addition, on-site storage of coal and coal residue can be a source of fugitive PM emissions.To determine the sources contributing to elevated PM10 levels in the region, a source apportionment study was performed at two locations (Hephziba and Pardes-Channa) during August/October 2017.We applied a microscopic chemical imaging (MCI) methodology based on particle fluorescence to determine PM source contributions in near-real time (GreenVision Systems, Ltd., Tel Aviv, "GVS").For the Hephziba monitoring site, located closest to the power plant and adjacent to a major highway, the major emissions sources were mobile sources (29.8%) and coal power plant emissions (29.1%).In addition, fugitive coal and coal residue were estimated to contribute 11.5% of the observed PM10.At the Pardes-Channa site, located further inland and in a more residential area, contributors included mobile sources (38.6%),coal power plant emissions (19.3%), and fugitive coal and coal residue (2.7%).These results indicate the significant impact of the power plant on observed PM10 in the region, with the nearby site also experiencing a major contribution from fugitive emissions from the facility.
