Polycyclic aromatic hydrocarbons (PAHs) were identified to be one of the major toxic air pollutants in urban environment. PAHs are mostly formed during incomplete combustion or pyrolysis of organic material. According to Serbian National Legislation Benzo(a)pyrene (BaP) concentration in total suspended particles (TSP) in ambient air in Belgrade Metropolitan has been determined in the last ten years, as a part of local air pollution monitoring program performed by Public Health Institute of Belgrade and funded by Belgrade?s Municipality. Air samples for analysis of BaP in suspended particles have been collected (as 24h sample once per month) at selected monitoring sites within municipal air quality monitoring network. At the beginning, According to National Regulation, all samples were taken as total suspended particles (TSP). Since middle of 2008, the procedure of sampling methodology was harmonized with EU requirements and solid fraction PM10 has been collected and analyzed using GC/MS. In this study, we have analyzed results of TSP collected between 2005 and-2008. Looking through the results obtained during the period of whole year, it can be noticed that concentrations of BaP were much higher during winter season at almost all measuring sites.

AbstractThe focus of this study is the assessment of total suspended particles (TSP) and particulate matter (PM) with various aerodynamic diameters in ambient air in Guayaquil, a city in Ecuador that features a tropical climate. The urban annual mean concentrations of TSP (Total Suspended Particles), and particle matter (PM) with various aerodynamic diameters such as: PM10, PM2.5 and PM1 are 31 ± 14 µg m−3, 21 ± 9 µg m−3, 7 ± 2 µg m−3 and 1 ± 1 µg m−3, respectively. Air mass studies reveal that the city receives a clean Southern Ocean breeze. Backward trajectory analysis show differences between wet and dry seasons. During the dry season, most winds come from the south and southwest, while air masses from the peri urban may contribute as pollutant sources during the wet season. Although mean values of PM10 and PM2.5 were below dangerous levels, our year-round continuous monitoring study reveals that maximum values often surpassed those permissible limits allowed by the Ecuadorian norms. A cluster analysis shows four main paths in which west and southwest clusters account for more than 93% of the pollution. Total vertical column of NO2 shows the pollution footprint is strongest during the dry season, as opposed to the wet season. A microscopic morphological characterization of ambient particles within the city during the wet and the dry season reveals coarse mode particles with irregular and rounded shapes. Particle analysis reveals that samples are composed of urban dust, anthropogenic and organic debris during the dry season while mainly urban dust during the wet season.

The increased occurrence of smoggy days in major Pakistan cities is of major concern to the general public. This paper explores the major sources of pollutants total suspended particles and lead concentration, a key contributor to the smog in Faisalabad, one of the largest cities in Pakistan. Evidence indicates that the total suspended particles and lead concentration formed through NOx, SOx, NH3, VOCs, etc. have a strong impact on human health. As a result, air pollution control should not simply focus on controlling particulate emission, but should involve adopting an integrated multi pollutant control strategy. In addition to identifying the major sources of air pollution, this paper explores its impact on environmental and human health. The results also compare with the permissible limit of NEQS and USEPA standards. The study shows that TSP concentration 80% values within the permissible limits of ambient air quality according to the standards of USEPA and NEQS. In the samples, Lead concentration is higher than the USEPA and NEQS standards of ambient air quality 1.5μg/m3 and 2μg/m3 respectively. The research suggests that adequate government regulation, public awareness, regional collaboration and industrial compliance are keys to successfully controlling air pollution.

Introduction. High density of oil-producing and refining facilities in certain areas of Bashkortostan significantly affects the environment including ambient air quality in residential areas. Materials and methods. We analyzed concentrations of airborne toxicants (sulfur and nitrogen oxides, nitrogen and carbon oxides, hydrogen sulfide, ammonia, xylenes, toluene, phenol and total suspended particles) and population health status in the cities of Ufa, Sterlitamak, Salavat, Blagoveshchensk, and the Tuymazinsky District in 2007–2016. Pearson's correlation coefficients (r) were used to establish possible relationships between medico-demographic indicators and air pollution. Results. Republican fuel and energy enterprises contributed the most to local air pollution levels. Gross emissions from such enterprises as Bashneft-Ufaneftekhim and Bashneft-Navoil reached 43.69–49.77 thousand tons of pollutants per year. The levels of some air pollutants exceeded their maximum permissible concentrations. Elevated concentrations of ammonia, total suspended particles, nitrogen dioxide, and carbon monoxide were registered most frequently. High rates of congenital abnormalities, respiratory diseases in infants (aged 0-1), general mortality and morbidity of the population were observed in some oil-producing and refining areas. The correlation analysis proved the relationship between the concentration of carbon monoxide and general disease rates in adults based on hospital admissions (r = 0.898), general incidence rates in children (r = 0.957), and blood disease rates in infants (r = 0.821). Respiratory diseases in children correlated with nitrogen dioxide emission levels (r = 0.899). Conclusions. Further development of oil-producing, petrochemical and oil-refining industries should be carried out taking into account socio-economic living conditions of the population.

In this study the origin of the carbonaceous fraction of total suspended particles (TSP) in air was analyzed. While the summer data show increasing carbon concentrations in the Los Angeles air basin from west to east, in the winter high levels of carbon particles can be found over the coast. The smallest and most dangerous particle fraction is principally composed of fossil carbon.

Reliable Analytical Method

An efficient and reliable analytical method has been used for determination of polybrominated diphenyl ethers (PBDEs) in atmospheric total suspended particles collected from the six state controlling air sampling sites and two self-selection sampling sites in Kunming, China. The results showed that the overall average concentrations of TSP collected from Kunming were in the range of 44.36 μg/m3 to 82.22 μg/m3. This pattern was lower than the average concentrations of Guiyu, Guangzhou and similar to Hong Kong. In TSP, the penta-BDEs and octa-BDEs were the dominant PBDEs and the PBDEs concentration ranged from 12.39 pg/m3 to 71.51 pg/m3, with a mean value of 46.82 pg/m3. This level was below the city of Guiyu, Örebro in Sweden and similar to Hong Kong, Guangzhou. The average concentrations of PBDEs had the trend of descent from the urban center to the outskirts of Kunming.
