“…The EF of Sb was higher than those reported in high-traffic cities such as Moscow, Russia (EF = 44) [19] and those registered in some roads in Barranquilla (EF close to 100) [25], but it was similar, and even lower, than those observed in high traffic roads in Viana do Castelo, Portugal (100 < EF <1000) [13]. Ramírez et al [24] reported a Sb enrichment factor close to 140 for commercial-use areas in Bogotá, which was lower than those found in this study.…”

“…Selenium showed the second-highest EF value in Manizales (EF = 576), a level that was higher than those reported in Bogotá [24] and Viana do Castelo [13]. The enrichment of Se is commonly associated with anthropogenic emissions, including combustion (coal, oil, wood, and biomass), non-ferrous melting, manufacturing, and use of agricultural products.…”

“…The latter ones generate adverse effects on human health, especially on the cardiorespiratory system [12]. Road dust loadings, as well as their chemical speciation, vary geographically depending on parameters such as meteorology, geology of the region, and even the type of pavement sampled [13,14].…”

Road dust (RD) resuspension is one of the main sources of particulate matter in cities with adverse impacts on air quality, health, and climate. Studies on the variability of the deposited PM10 fraction of RD (RD10) have been limited in Latin America, whereby our understanding of the central factors that control this pollutant remains incomplete. In this study, forty-one RD10 samples were collected in two Andean cities (Bogotá and Manizales) and analyzed for ions, minerals, and trace elements. RD10 levels varied between 1.8–45.7 mg/m2, with an average of 11.8 mg/m2, in Bogotá and between 0.8–26.7 mg/m2, with an average of 5.7 mg/m2, in Manizales. Minerals were the most abundant species in both cities, with a fraction significantly larger in Manizales (38%) than Bogotá (9%). The difference could be explained mainly by the complex topography and the composition of soil derived from volcanic ash in Manizales. The volcanic activity was also associated with SO4⁻2 and Clˉ. Enrichment factors and principal component analysis were conducted to explore potential factors associated to sources of RD10. Elements such as Cu, Pb, Cr, Ni, V, Sb, and Mo were mainly associated with exhaust and non-exhaust traffic emissions.

“…The carcinogenic risk due to exposure to PAHs is based on benzo[a]pyrene equivalent concentrations (BaP eq ). These are calculated multiplying the individual PAH concentrations by their toxic equivalent factor (TEF) [ 44 ]. The inhalation cancer unit risk of BaP is 1.11 × 10 −6 (ng m −3 ) −1 .…”

Passive diffusion tubes for volatile organic compounds (VOCs) and carbonyls and low volume particulate matter (PM2.5) samplers were used simultaneously in kitchens and outdoor air of four dwellings. PM2.5 filters were analysed for their carbonaceous content (organic and elemental carbon, OC and EC) by a thermo-optical technique and for polycyclic aromatic hydrocarbon (PAHs) and plasticisers by GC-MS. The morphology and chemical composition of selected PM2.5 samples were characterised by SEM-EDS. The mean indoor PM2.5 concentrations ranged from 14 µg m−3 to 30 µg m−3, while the outdoor levels varied from 18 µg m−3 to 30 µg m−3. Total carbon represented up to 40% of the PM2.5 mass. In general, the indoor OC/EC ratios were higher than the outdoor values. Indoor-to-outdoor ratios higher than 1 were observed for VOCs, carbonyls and plasticisers. PAH levels were much higher in the outdoor air. The particulate material was mainly composed of soot aggregates, fly ashes and mineral particles. The hazard quotients associated with VOC inhalation suggested a low probability of non-cancer effects, while the cancer risk was found to be low, but not negligible. Residential exposure to PAHs was dominated by benzo[a]pyrene and has shown to pose an insignificant cancer risk.

“…While some researchers reported a positive association between PM 2.5 particulates and the cardiovascular and respiratory complications [8][9][10][11][12][13][14], other researchers reported a positive association between PM 10 and higher rates of hospitalization due to ischemic heart disease and carcinoma [15][16][17]. A more detailed literature review on various chronic diseases resulting from the fugitive dust can be found elsewhere [18][19][20][21]. In a recent data analysis carried out by Wu et al [22] using data from the United States, a positive association between the long-term exposure to PM 2.5 and the increased risk of COVID-19 (Coronavirus disease 2019) was reported, i.e., an increase of only 1 µg/m 3 in PM 2.5 is associated with an 8% increase in the COVID-19 death rate in the United States.…”

Fugitive Dust Suppression in Unpaved Roads: State of the Art Research Review

et al. 2021

View full text Add to dashboard Cite

Fugitive dust is a serious threat to unpaved road users from a safety and health point of view. Dust suppressing materials or dust suppressants are often employed to lower the fugitive dust. Currently, many dust suppressants are commercially available and are being developed for various applications. The performance of these dust suppressants depends on their physical and chemical properties, application frequency and rates, soil type, wind speed, atmospheric conditions, etc. This article presents a comprehensive review of various available and in-development dust suppression materials and their dust suppression mechanisms. Specifically, the dust suppressants that lower the fugitive dust either through hygroscopicity (ability to absorb atmospheric moisture) and/or agglomeration (ability to cement the dust particles) are reviewed. The literature findings, recommendations, and limitations pertaining to dust suppression on unpaved roads are discussed at the end of the review.
