“…10A). 342,360 The results are not always very convincing, 301,340 mostly because relatively large concentration differences can occur over small distances and the number of sampling sites is generally insuf-cient. When seeking to map urban air pollution, a minimum number of sampling sites of 0.29 multiplied with the urban surface to be monitored in km 2 has been recommended, based on work with VOCs and NO 2 .…”

“…It is quite common to analyze soil samples taken at or in the vicinity of passive air sampling sites, 301,353,364,377,459,460,476,551 for example to compare the relative composition of PCB mixtures in different media. 387 In particular, spatial trends of concentrations in air and soil along elevation gradients have been used to study the occurrence of mountain cold trapping.…”

“…Among the heavier PAHs, benzo[g,h,i]perylene and indeno[1,2,3cd]pyrene show concentrations above the LODs. Generally, these two pollutants are related to diesel vehicular emissions [46][47][48][49][50][51][52] whereas the petrol vehicle emissions are characterized by B[a]P and dibenzo [ah]anthracene emissions [53][54][55][56][57]. For coal combustion, the PAHs profiles are generally characterized by a high presence of fluoranthene, pyrene, phenanthrene and anthracene, to which the chrysene and the isomer of benzo[k]fluorantene are added [58][59][60][61].…”

PM10 and PM2.5 Qualitative Source Apportionment Using Selective Wind Direction Sampling in a Port-Industrial Area in Civitavecchia, Italy

et al. 2020

The possibility to discriminate between different emission sources and between natural and anthropogenic contributions is a key issue for planning efficient air pollution reduction and mitigation strategies. Moreover, the knowledge of the particulate matter (PM) chemical composition for the different size fractions is recognized as increasingly important, in particular with respect to health effects of exposed population. This study is focused on the characterization of PM10 and PM2.5 main sources located in the Civitavecchia harbor-industrial area (Central Italy), namely a large coal-fired power plant, a natural gas power plant, the harbor area, the vehicular traffic (due to both the local traffic and the highway crossing the area) and small industrial activities. The approach was based on PM10/PM2.5 samples monthly collected for one year and a further relative chemical characterization of organic and inorganic fractions. Wind-select sensors, allowing a selective PM10 and PM2.5 sampling downwind to specific emission sources, were used for the overall sampling. This methodology manages to explain specific emission patterns and to assess the concentration levels of the micro pollutants emitted by local sources and particularly toxic for health. A descriptive statistical analysis of data was performed, also verifying the occurrence of legislative threshold exceedances. Moreover, in order to highlight the contribution of specific sources, the differences in the measured micro pollutants concentrations between wind directions, PM size fractions and sampling sites have been investigated, as well as the seasonal trends of pollutants concentrations. These results allow to highlight that the applied methodology represents a valid support in source apportionment studies.

“…Several concentrations of PAH have been reported in topsoil and various environmental compartments from a number of cities around the world, underscoring the fact that PAH pollution is a major environmental concern especially in urban areas and cities with high levels of anthropogenic activities (Alegbeleye et al 2017). Some of these regions include China (Tang et al 2005;Zheng et al 2014;Wang et al 2015Wang et al , 2017, South Korea (Nam et al 2003), India (Gune et al 2019;Tarafdar and Sinha 2019), Portugal (Cachada et al 2012), Germany (Martens et al 1997), United Kingdom (Lorenzi et al 2010), Ghana (Bortey-Sam et al 2014;Bandowe and Nkansah 2016), South Africa (Nieuwoudt et al 2011;Okedeyi et al 2013;Munyengabe et al 2017;Omores 2017), and Kenya (Mungai et al 2019).…”

There is an intrinsic link between polycyclic aromatic hydrocarbons (PAHs) accumulated in soils and increased health risk to humans after exposure to contaminated soil via ingestion, inhalation of particulates carrying PAHs, and direct contact with polluted soils. However, the assessment of PAH contamination in most developing countries fails to consider health risk assessment. Therefore, a comprehensive study was conducted to determine the concentration, source, toxicity, and human health risks of 16 PAHs in an urban area in Warri, Delta State, in the Niger Delta region of Nigeria. The results showed varying contamination levels for PAH in soil samples from all sampling points, with benzo[a]anthracene (BaP; at 338.81 μg/kg) being the most abundant at all 9 sampling stations. The highest total concentration of PAH was observed at station 5 (1230.98 μg/kg), which was closest to a flow station. Further comparison with PAH contamination standards showed that soils from stations 1 and 2 were weakly contaminated (<600 μg/kg), and soil samples from stations 3, 4, 6, 7, and 9 were moderately contaminated (<1000 μg/kg). Soil samples from stations 5 and 8 were observed to be heavily contaminated (>1000 μg/kg). The BaP estimates for soil samples obtained for stations 3 to 9 were higher than the BaP soil screening value (15 μg/kg), indicating a carcinogenic potential of soil samples. The results also showed that the incremental lifetime cancer risk estimates for PAH in the soil for adults and children were above the recommended threshold (10 −4) for ingestion and dermal contact, implying that exposure to contaminated soil could lead to cancers in adults and children. Currently, there are no regional or national standards for PAHs in soil that would indicate an increased likelihood for human exposure and subsequent health issues.
