Numerous studies have reported that particulate matter (PM) and its specific chemical constituents were linked to the incidence of respiratory diseases and mortality and lung function. The main aim ...of this study is to determine metallic content in PM10 and PM2.5 samples taken simultaneously at several locations in the close vicinity of the copper smelter in Bor and the influence of outdoor PM pollution on indoor PM levels. The measurement campaign was conducted, during the non-heating season of 2020. The PM samples were collected at all sampling sites with low-volume samplers (Sven/Leckel LVS3) on quartz fiber filters (Whatman QMA, 47mm). All samples were analyzed by inductively coupled plasma mass spectrometry (ICP MS). In this way, the mass concentrations of four priority elements (As, Cd, Pb, and Ni) in PM samples were identified and quantified. It has been determined that average indoor PM levels in the laboratory were higher than outdoors. A strong correlation was found between PM10 and PM2.5 particle levels inside the laboratory and in the outdoor air. Also, a very strong correlation was found between the levels of Pb, Ni, As, and Cd determined in PM10 and PM2.5 samples inside the laboratory and in the outdoor air. This confirms that mentioned elements originate from the same sources located in the copper smelter complex.
This paper presents the results of measurements the suspended particles of the PM 10 and PM 2.5 fractions in two high schools in Bor (School of Mechanical and Electrical Engineering-MS and Grammar ...School-GM). The measurements were conducted in two heating seasons for a duration of seven days (five weekdays, and two weekend days). Periods during the weekdays when there were classes and weekend days when there were no classes at school were analyzed separately. The measurement results show that the average concentrations of suspended particles PM 10 during the class period were 1.7 (GM) and 2.4 (MS) times higher than in the period without classes. The average concentrations of suspended particles PM 2.5 in both schools during the class period were 1.5 times higher than in the period without classes. In MS the average PM 10 and PM 2.5 concentrations during classes were above daily limit values for 3 of 5 working days. In contrast, there was no exceeding of the average daily limit values for concentrations of suspended particles during classes in GM. The results of measurements indicate that more attention should be paid to the way classrooms are cleaned to reduce the possibility of particles resuspension due to the movement of pupils during the teaching period.
