“…The subsequent equations were extensively applied to estimate the ILCR in terms of ingestion, dermal contact and inhalation: (Peng et al, 2011). BW: Body weight of child (15 kg) and adult (61.5 kg) (Shi et al, 2011 ). Note that the model for children (1-6 years old) and adults (7-31 years old) were based on the Risk Assessment Guidance of U.S. EPA and related publications.…”

In Northern Thailand, wildland fire during cold period releases large amounts of smoke and fine particles into the atmosphere. The fine particles include several persistent organic compounds such as PAHs. In this study, PM 2.5 -bound PAH concentrations in the air of nine administrative provinces, namely Chiang-Mai, Chiang-Rai, Nan, Phayao, Mae Hong Son, Phrae, Lampang, Lamphun, Uttaradit (N Thailand) were determined during the wildland fire and non-wildland fire seasons. The monitoring strategy comprised two campaigns in each season. PM 2.5 was collected using MiniVolTM portable air samplers (Airmetrics) with quartz fibre filters. Both PAHs and their B[a]P Equivalent concentrations of other urban cities around the world were significantly higher than those of northern provinces for both seasons. The average cancer risks observed at nine administrative provinces were 8.525 × 10 -4 ± 3.493 × 10 -3 and 2.558 × 10 -3 ± 6.986 × 10 -3 for ingestion rate of 50 and 100 mg day -1 , respectively. The excess cancer risks of world cities for ingestion rate of 50 and 100 mg day -1 were much higher than those of Northern Thailand for 851 and 567 times in that order. Dust ingestion was exceedingly critical to non-dietary PAH exposure in comparison with PM 2.5 inhalation. These results are in good agreement with those of previous studies, underlining the significance of indoor air quality on long-term adverse respiratory diseases in Asian cities.

“…Urban dust often contains high levels of toxic heavy metals and organic contaminants (Langer et al 2010, Lu et al 2010, Chłopek et al 2016 owing to various anthropogenic sources such as industrial emissions, traffi c emissions, coal and fuel combustion, waste disposal, municipal activities, construction, and residential heating (Thorpe andHarrison 2008, Lu et al 2014). Due to their toxicity, persistence, bioaccumulation, and biomagnifi cations, heavy metals in dust pose a potential threat to ecological systems and human health (Shi et al 2011). Heavy metals concentrated in dust can be easily transferred into the human body by inhalation, ingestion and dermal contact absorption (Glorennec et al 2012).…”

“…Although most of the existing studies were carried out in developed countries or the megacities of developing countries (Banerjee 2003, Han et al 2006, Shi et al 2011, Nazzal et al 2013, Tang et al 2013, limited information is available on heavy metal contamination of street dust in rapidly industrializing and urbanizing medium and small cities (Lu et al 2014). Differences among cities, including population density and industrial activities, could have a large impact on the fi ndings of individual studies (Lu et al 2014).…”

Environmental risks associated with Co, Cr, Cu, Mn, Ni, Pb, V and Zn in street dust collected from Baotou, a medium-sized industrial city in a semi-arid area of northwest China, were assessed by using enrichment factor and the potential ecological index. Their spatial distributions and sources in the dust were analyzed on the basis of geostatistical methods and multivariate statistical analysis, respectively. The results indicate that street dust in Baotou has elevated heavy metal concentrations, especially of Co, Cr, Cu, Pb and Zn. Co in the dust was signifi cantly enriched. Cr and Pb were from moderate to signifi cant enrichment. Cu and Zn were from minimal to moderate enrichment, whereas Mn, Ni and V in the dust were from defi cient to minimal enrichment. The ecological risk levels of Co and Pb in the dust were moderate to considerable and low to moderate, respectively, whereas those of other heavy metals studied in the dust presented low ecological risk. Different distribution patterns were found among the analyzed heavy metals. Three main sources of these heavy metals were identifi ed. Cr, Mn, Ni and V originated from nature and industrial activities. Cu, Pb and Zn derived mainly from traffi c sources, and Co was mainly from construction sources.

“…: Dong and Lee, 2009;Shi et al, 2011;Pant and Harrison, 2013), up to now does not exist a dedicated model to perform the risk assessment for this matrix. Indeed, most of the researches focused on this topic use the approaches provided by US Environmental Protection Agency which allow to estimate the soil contamination of superfund sites (USEPA, 1996(USEPA, , 2002, to evaluate the exposure pathways of RD matrix and the respective potential health risks (e.g.…”

Road dust is a non-exhaust source that can significantly contribute to atmospheric particulate by resuspension. Beside the issue of the overcoming of guidelines limits for the air quality, the characterization of this matrix is of crucially high interest for the inherent toxicity of resuspended particles, that can act as carriers of heavy metals and toxic-carcinogenic components.In this paper, road dust collected in the Venice international airport is characterized with a multi-technique approach in order to identify the main pollutant sources and to highlight the differences between airside/ landside places. The most polluted sites are identified and a preliminary risk assessment is performed taking into account ingestion, dermal intake and inhalation of fugitive particulate pathways. Specifically, the main sources are related to construction activities, anti-icing safety procedures, and brake, tire and road wear; streets are the most polluted landside places; PAHs, Na, Al, Cu, Zn, Ag, Cd are more concentrated in airside area; as regards the risk assessment As, BaP, Cr, Sb, BaA, and BbF are the most critical pollutants.
