“…Atmospheric pollution was also measured indirectly by moss bags or soil [4,38] and it indicates a greater incidence of PAHs in an urban air, typically concentrated near urban centres and their concentrations correlate with transport or with combustion of fuels. Lower concentrations are found in outdoor air in remote areas [9] or due to long…”

Abstract. The contaminants present in the atmosphere have a substantial impact on public health. Among contaminants, the most important are polycyclic aromatic hydrocarbons (PAHs).This paper is focused on the possibility of continuous PAHs monitoring and the description of their vertical distribution using filters, which serve to purify the air before the determination of the greenhouse gases (CO 2 , CH 4 , N 2 O, CO, ozone) and Hg in air, continuously sampled at 8, 50 and 230 m at the atmospheric station Křešín near Pacov and elaboration of a simple and economical method of extraction of these filters.The station serves as a point for monitoring the occurrence and remote transport of greenhouse gases and selected atmospheric pollutants and for the measurements of basic meteorological characteristics.In December, 17, 2014, a sampling of 16 priority PAHs started and lasted until December, 9, 2015. Samples were taken approximately once a month. The maximum concentration of ΣPAHs was 15.905 ng/m 3 , measured at the height of 8 meters in the period of 11. 2. 2015-11. 3. 2015, the concentration of benzo[a]pyrene exceeded the immission limit in this period by more than 50 %.By the sampling, the hypothesis about decreasing concentration of PAHs with increasing height was confirmed, especially the decrease of heavier PAHs.The sampling has shown that it is highly desirable to use the meteorological tower for sampling of PAHs using PTFE filters either by including the active sampler itself, or by using pre-filters for tropospheric ozone and gaseous elemental mercury analysers.

“…The results obtained in the study have been presented in Table 1. After analyzing PAHs in snow and moss, Viskari et al (1997) confirmed that snow appears to be a good collector of pollutants from the atmosphere and can be used to monitor local airborne pollution from road traffic. Similarly, extensive research on PAH related to deposition of motor vehicle emission along roadside was carried out by Hautala et al (1997).…”

Abstract:The main objective of this article is an attempt to use snow as an indicator in the process of assessing and identifying vehicle-derived elements pollution. The aim of the present study is to characterize traffic-related elements in snow collected from three sites: a parking place, a highway and a relatively unpolluted airfield. Several recent studies suggest that road traffic is considered to be one of the major sources of environmental pollution in urban areas. In order to avoid the problem of low emission from household furnaces, samples were collected far away from residential buildings. Snow located near roads with heavy traffic seems to be a very useful tool and indicator of trafficrelated elements released into the environment. Snow acts as a natural filter for various chemical elements and particles. Snow is an efficient scavenger of aerosol and air pollutants, usually remains on the ground for sampling after the event; moreover, snowmelt contaminates soil. In the present study filtered (0.45 µm) samples of melted snow were analyzed with ICP-MS. The results show significantly higher concentrations of elements in snow collected at the parking lot and at the highway when compared to samples taken from a relatively unpolluted airfield. Research on exploitation dust (break, tire, clutch) was performed with SEM-EDS.

“…After their atmospheric transportation and dry or wet deposition, processes that are strongly dependent on the relationship between vapor pressure and molecular weight [11], PAHs tend to accumulate in vegetation. Biomonitoring of PAHs on plants gained popularity in the last four decades [12][13][14][15]. The application of moss as passive accumulator for PAHs is widespread in so-called air quality assessment studies, because of (i) their strong presence at the local scale, (ii) their relative cost-effective methodology (compared to physicalchemical approach) [15], (iii) their morphological and physiological properties [16][17].…”
