“…No specific chronological trend was observed. The PAA contribution rise with decreasing particle size, reaching the maximum value of 37%, on average, at size 0.10-0.056 μm, coherent with the combustion processes emitting in the finer fractions of aerosols (Cesari et al, 2020). The average contribution of OA to total suspended particulate was 14% (range 9-27%), comparable to a previous work (Perrino et al, 2009).…”

“…To our knowledge this is the first work in Europe evaluating simultaneously major ions, trace metals, and carbonaceous species in the same samples, in so much different aerosol size ranges and the first work detailing the size-dependent contribution of primary ship traffic to particles smaller than 1 μm using chemical tracers. A detailed description of carbonaceous species concentration and size distribution was given in (Cesari et al, 2020), where a comparison between OC and EC results obtained in Venice and Rijeka (Croatia) is reported.…”

“…The ambient particulate matter (PM) pollution is a serious environmental concern, which adversely impacts the human health and natural environment. The ambient PM pollution leads to air quality degradation, haze formation, reduced visibility, climate change, global warming, ecosystem deterioration, and human health risks (Ari et al, 2020;Cesari et al, 2020;Jain et al, 2020). The ambient PM originates from diverse primary sources (anthropogenic and natural), as well as in the form of secondary particles formed by the photochemical processes involving both the anthropogenic and natural precursors (Dai et al, 2019;Zalakeviciute et al, 2020).…”

The ambient particulate matter (PM) pollution adversely influences the human health and natural environment. The size distribution of ambient PM determines the physiochemical and optical properties of ambient aerosol, whereas it reflects the variability in local and regional PM emission sources and formation mechanisms. In the present work, the size distribution and characteristics of the carbonaceous, ionic, elemental, and saccharide species were categorically investigated for the fraction-wise PM in Tianjin during 2018 early summer. The average concentrations were 32.4, 20.9, and 49.3 μg/m3 for the PM1, PM1–2.5, and PM2.5–10, respectively. The coarse PM2.5–10 accounted for most of the PM10 mass (47%), followed by the fine PM1 (33%) and intermodal PM1–2.5 (20%). The carbonaceous and ionic species exhibited bimodal distribution and were distributed mostly to the fine size fraction and then to the coarse size fraction. The elemental species exhibited unimodal distribution and were distributed mostly to the coarse size fraction. The specific saccharide species indicated the significant contribution of biomass burning and primary biogenic emissions. The bimodal mass size distribution of levoglucosan indicated the significant biomass burning contributions to the fine and coarse size fractions. The unimodal glucose, fructose, and arabitol distribution and the bimodal mannitol distribution indicated the dominant primary biogenic contributions to the coarse size fraction. The PM1/PM10, PM1–2.5/PM10, PM2.5–10/PM10, OC/EC, SOC/OC, AE/CE, NO3–/SO42–, K+/EC, and levoglucosan/K+ ratios were used to investigate the characteristics of the ambient size-fractionated PM. The anthropogenic sources (combustion processes, traffic emissions, and secondary particles, etc.) contributed mostly to the fine PM1 and intermodal PM1–2.5 fractions, whereas the natural sources (primary biogenic, marine salt, and mineral dust, etc.) contributed mostly to the coarse PM2.5–10 fraction. This work is a significant addition to the multi-size ambient PM’s size distribution and characterization studies.

Road traffic is one of the main sources of particulate matter in the urban environment, emitting particulate organic and elemental carbon compounds and metal-rich particles through combustion and brakes and tires wear. In Western Africa, the carbon and metal composition of airborne particles is also influenced by additional sources linked to biomass combustion and recent industrialization. Here, we investigated the impact of combustion-related and non-combustion-related emissions on the distribution of carbonaceous fractions and iron-rich particles in two urban environments in France and Senegal. The supermicron fraction ($$D_a>{1}$$ D a > 1 µm) showed a significantly higher isothermal remanent magnetization (SIRM) than finer fractions, accounting for 79% in France and 81% in Senegal of the total SIRM. In the submicron fraction ($$D_a<{1}$$ D a < 1 µm), we noted significantly higher concentrations of total carbon (TC) and elemental carbon (EC) than for other fractions, both accounting for 71% in France and 68% and 75% in Senegal of the total and elemental particulate carbon concentration, respectively. Electron microscope observations revealed the presence of iron-rich particles for $$D_a<{0.2}$$ D a < 0.2 µm, however, associated with a weak SIRM. Such iron particles may be produced by combustion or abrasion while we suspect that emissions by the abrasion process produce larger particles.
