ABSTRACT
Air pollution control must rely on multi-criteria pilot studies, using equipment and adequate information to provide the screening and continuous monitoring of air pollution in a specific urban area. Fine and ultrafine particles have a high toxic potential for human health. The main aim of the study was to perform a screening of the outdoor and indoor fine and submicrometric fractions of particulate matter (PM) in Valahia University Campus, Targoviste, Romania, to assess the exposure of students and academic personnel. Therefore, the monitoring campaigns were conducted between the "rush" hours of traffic (8.00-12.00 a.m. and 2.00-6.00 p.m.) using two optical devices i.e. DustTrak DRX 8533 EP aerosol analyzer that simultaneously measures the size segregated mass fraction concentrations (PM1, PM2.5, Respirable/PM4, PM10/Thoracic, and TPM) in real time, and Casella Microdust Pro. We used a multiparameter device to measure the weather parameters (temperature, relative humidity, wind speed, and air pressure) during PM sampling. The criteria for establishing the monitoring points took into account the proximity to a main entry road with intense traffic in Targoviste city and industrial emission sources from north of the Campus. These measurements are important for establishing the optimal location for a station of PM and meteorological continuous monitoring within the campus. Results pointed out that the average of PM2.5 varied from 35-42 μg m-3 (points located near the road) to 10-12 μg m-3 (middle of the campus) and 6-8 μg m-3 (near the border with Ialomita River). Qualitative PM data are essential for structuring epidemiological studies in view to consolidate the knowledge on influences that prolonged exposure may have on human health.
