Assessment of PM2.5 and PM10 Emissions in the Metallurgical Industry from Romania

Abstract

The article focuses on the evaluation of PM2.5 and PM10, pollutants resulting from the metallurgical industry in Romania. The analysed period is 2008-2018 and the dataset was provided by the National Institute of Statistics. The purpose of this paper is to examine the impact of final energy consumption in the metallurgical industry on PM10 and PM2.5 emissions. We included in the study three fundamental factors: the final energy consumption in the metallurgical industry and the particulate matter (PM10 and PM2.5). The average of PM10 for reference period is 4026 Tone (Mg) while for the PM2.5 the average is 3645 Tone (Mg). The trend of final energy consumption in the metallurgical industry is identical to the trend of PM2.5 and PM10, which indicates that this factor has a major influence on the amount of PM2.5 and PM10 emissions. PM2.5 and PM10 emission factors represent primary emissions from the metallurgical industry activities and do not consider the formation of secondary aerosol from chemical reaction in the environment afterwards the discharge.
