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

Abstract

The article focuses on the evaluation of PM_2.5 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 PM_2.5 emissions. We included in the study three fundamental factors: the final energy consumption in the metallurgical industry and the particulate matter (PM₁₀ and PM_2.5). The average of PM₁₀ for reference period is 4026 Tone (Mg) while for the PM_2.5 the average is 3645 Tone (Mg). The trend of final energy consumption in the metallurgical industry is identical to the trend of PM_2.5 and PM₁₀, which indicates that this factor has a major influence on the amount of PM_2.5 and PM₁₀ emissions. PM_2.5 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.
