Air Quality Monitoring in Jiu Valley

Abstract The paper presents air quality monitoring in Jiu Valley, which is carried out at HD-5 Vulcan monitoring station, starting with March 2010, allowing the obtaining of useful data for the rapid identification of polluted areas and for taking strategic decisions by competent factors and tactics to combat and prevent pollution. After highlighting the pollution sources in Jiu Valley, we present both the evolution of hourly and / or daily values of pollutants recorded at the automatic HD-Vulcan air quality monitoring station during 2020: SO2, NO2, CO, gravimetric PM10, Pb, Cd and Ni, but also the evolution of air quality for quality indicators, monitored in Hunedoara County (including Jiu Valley, at HD-5 station), during 2010-2020. Taking into account the average annual values of pollutants recorded in 2020 at HD-5 Vulcan station, the paper calculates air quality indices for each pollutant and then indicates air quality throughout Jiu Valley in 2020, establishing that air quality is good in this area, with a very low level of pollution and no effect on humans, ecosystems and materials.
