MONITORING AND CHARACTERISATION OF SUSPENDED AND SETTLED INDOOR PARTICULATE MATTER
Abstract
The presence of aerosol particles is strongly related with increased morbidity and mortality even at the ordinary aerosol concentration levels that occur in the urban environment. Aerosols contamination of indoor environment can originate from both outdoor and indoor sources (cooking, smoking etc.). Dangerous effect of particles consists in their penetration and deposition into human respiratory system. Because of inhalation exposure not only particulate size is important, but also particulate matter’s chemical composition implies toxic health effect on human organism. The paper is aimed to the both settled and suspended particulate mater investigation in selected residential building in Kosice city in Slovakia. Settled particulate matter sampling was carried out by passive method, suspended particulate matter sampling was focused on total suspended particles (TSP) and thoracic fraction PM10. The surface concentrations of settled particulate matter were in range from 276,43 mg/cm2 to 570,70 mg/cm2 detected, mass concentrations of total suspended particulate matter from 59, 028 to 114, 583 mg/m3. The presence of selected metals in samples was detected by atomic absorption spectrometry (AAS). The morphology was studied by scanning electron microscopy (SEM).
