Abstract:
Air pollution is a problem today, and it is essential to know how high it is. By increasingpeople's standard of living, increasing the number of factories, cars and citizens, it ishelpful to know how much pollution is distributed and whether it does not exceed thestandards allowed for pollution. It is necessary to investigate air pollution with heavymetals in Jelgava by identifying data from areas. In preparing the analysis, it is possibleto assess whether air quality is adequate and does not exceed pollution standards. So far,Jelgava has not collected data and air quality problems, so it cannot be concluded whetherair quality complies with norms. The aim of the work is to prepare an analysis of thepollution and distribution of heavy metals in the Jelgava urban environment, using theresults of the study of the 2019 snow samples. Snow samples were harvested on 31January 2019. On the day of sampling, the snow had sustained more than seven days afterthe first snowfall. Sampling sites were roughly distributed across all areas of the city.Three samples of snow, which are control samples, were harvested in the rural area.Samples were analyzed with induction-coupled plasma spectroscopy (ICP-OES). Ananalysis of pollution data shows that air pollution with heavy metals is higher in denselypopulated areas but less in open spaces. Air quality is significantly affected by the use ofunsuitable or low-quality fuels in residential heating buildings. The highest zinc, copper,and calcium concentrations are observed in a snow sample taken in the residential area.
