Iron, Cr, Ni, Co, Mo and Cu levels were significantly associated with road class, with the highest concentrations measured for the expressway. Most elements, especially Sb and Zn, were enriched in thoracic sweepings. The PCA results demonstrate the importance of non-fossil fuel, traffic-related elemental emissions. Difficulties in identifying sources, given uncertainties regarding overlapping chemical profiles, are also highlighted. Significant elemental loadings to roads were estimated to occur, with the largest amounts identified for Fe, Al, Mn, Zn, Cr and Cu. Road dust resuspension is predicted to be the most important source of emissions for Fe, Al, Mn, Cr, V, Sn, Mo, Co and Sb.]]> Thu, 24 Jun 2021 16:40:49 GMT https://trid.trb.org/View/1849965 Spatial distribution and sources of potentially toxic elements in road dust and its PM₁₀ fraction of Moscow megacity https://trid.trb.org/View/1748151 65% of their total contents in road dust); Cu (> 50%); and Cd, Pb, Mo, Co, Ni (30–50%). PM₁₀ fraction was 1.2–6.4 times more polluted with PTEs than bulk samples. Resuspension of roadside soil particles accounted for 34% of the mass of PTEs in road dust and for 64% in the PM₁₀ fraction. Other important sources of PTEs were non-exhaust vehicles emissions (~ 20% for dust and ~ 14% for PM₁₀) and industrial emissions (~ 20% and ~ 6%). The road dust and PM₁₀ particles were most contaminated in the central part of the city due to the large number of cars and traffic congestions. Local anomalies of individual PTEs were observed near industrial zones mainly in the west, south, and southeast of Moscow. In the yards of residential buildings the total enrichment of road dust and PM₁₀ with PTEs was only 1.1–1.5 times lower than that on major roads which poses a serious danger to the population spending a significant part of their lives in residential areas. The spatial pattern of the PTEs distribution in road dust and its PM₁₀ fraction should assist in more efficient planning of washing and mechanical cleaning of the road surface from dust to minimize the risk to public health.]]> Mon, 30 Nov 2020 11:15:44 GMT https://trid.trb.org/View/1748151 Loadings, chemical patterns and risks of inhalable road dust particles in an Atlantic city in the north of Portugal https://trid.trb.org/View/1709753 Tue, 23 Jun 2020 12:30:41 GMT https://trid.trb.org/View/1709753 Reliability of Nanofluid Concentration on the Heat Transfer Augmentation in Engine Radiator https://trid.trb.org/View/1503367 Wed, 11 Apr 2018 11:37:00 GMT https://trid.trb.org/View/1503367 Physico-chemical kinetics of structural build-up of neat cement-based suspensions https://trid.trb.org/View/1466945 Mon, 05 Jun 2017 18:05:22 GMT https://trid.trb.org/View/1466945 The zeta potential of cement and additions in cementitious suspensions with high solid fraction https://trid.trb.org/View/1464221 Mon, 15 May 2017 15:16:47 GMT https://trid.trb.org/View/1464221 New approach to assess build-up of cement-based suspensions https://trid.trb.org/View/1410726 Mon, 13 Jun 2016 17:43:28 GMT https://trid.trb.org/View/1410726 EFFECT OF THE STRUCTURES OF POLYCARBOXYLATE-BASED DISPERSANT ON THE VISCOSITY OF CaCO₃ SUSPENSION AND THE ADSORPTION CHARACTER OF DISPERSANT ON CaCO₃ https://trid.trb.org/View/1351648 Fri, 22 May 2015 16:14:08 GMT https://trid.trb.org/View/1351648 RHEOLOGICAL MODELING FOR CONCENTRATED FLOCCULATED SUSPENSIONS CONSIDERING THE EFFECT OF PRIMARY PARTICLE SIZE DISTRIBUTION https://trid.trb.org/View/1351645 Fri, 22 May 2015 16:14:02 GMT https://trid.trb.org/View/1351645 Experimental Study on Characteristics of Oil Particle Distribution in Water-Gelled Crude Oil Two-Phase Flow System https://trid.trb.org/View/1312675 Mon, 30 Jun 2014 09:41:03 GMT https://trid.trb.org/View/1312675 ON RHEOLOGICAL APPROACH TO ESTIMATE FRACTAL STRUCTURE OF AGGREGATE IN CEMENT PASTE https://trid.trb.org/View/1284289 Tue, 22 Apr 2014 16:07:01 GMT https://trid.trb.org/View/1284289
