| Abstract [eng] |
In final master thesis air quality was analyzed and assessed in the vicinity of oil refinery using snow-cap as an indicator. Analysis of snowmelt water and snow-dust was used to determine concentrations of anthropogenic pollutants such as: sulphates, chlorides, nitrites, nitrates, ammonium nitrogen, total carbon, total nitrogen and heavy metals: lead (Pb), copper (Cu), chromium (Cr), cadmium (Cd). In this study analysis was conducted considering different distances and the wind direction within the impact zone of the oil refinery. The load of snow-dust was evaluated to determine the pollution level in the study area. For modeling were used ADMS 4 and AERO 2 models to simulate PM dispersion in the atmosphere from 6 point pollution sources (stacks). The results obtained during the simulation were compared with the results of experimental analysis. Structure: introduction, review of the literature, methodology, modeling of PM dispersion in the atmosphere using ADMS 4 and AERO 2 models, results and analysis, conclusions and suggestions, references. Thesis consists of: 80 p. texts without appendixes, 36 pictures, 9 tables, 77 bibliographical entries. Appendixes included. |
