Abstract:
Knowledge of air quality is important for human and enviroment health. Therefore, this work is dedicated to analysis the indoor and outdoor of air pollution. The measurements were performed for suspended material particles (PM10) content and ozone concentrations at ground level. For this study, were used several devices: Low Volume Sampler Sven Leckel, DustTrak Model 8533 and Model 202 Ozone Monitor. The Low Volume Sampler Sven Leckel was running continuous outdoor with the filter changed at every 24 hours, the resulted filters were investigated by weighting after which small pieces were cut and investigated by electron microscopy. The study was performed at Faculty of Physics in an urban location Magurele, Romania. For better assessment, the suspended material particles investigations were carried outdoor and indoor, the ozone concentrations were measured outdoor. The outdoor values of PM10 mass concentrations from Magurele were compared with measurements values from a rural location, named Surlari to assess air quality for breathing concerns. The results emphasized PM10 mass concentration under 40 but bigger than at rural station. The values of average PM (PM1, PM2.5, PM4, PM10) measured using DustTrak indoor are smaller than those measured outdoor. The ozone concentration values increase in 14-18 hour interval due to the enhancing of photochemical reaction in presence of NO2 pollutant due to traffic.
