An inter-comparison of size segregated carbonaceous aerosol collected by low-volume impactor in the port-cities of Venice (Italy) and Rijeka (Croatia)

Chemical characterization and source apportionment of size-segregated aerosol in the port-city of Venice (Italy)

“…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).…”

“…Punches of 1 cm 2 were analysed according to the EUSAAR2 protocol, designed as the European standard procedure in the European Supersites for Atmospheric Aerosol Research. The procedure is described in (Cesari et al, 2020) and Merico et al (2019a).…”

“…More details about the concentration of ions and metals and their size distribution are reported in the Supplementary Material. A deep description of OC and EC trend in these samples and of their size distribution was given in (Cesari et al, 2020).…”

“…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.…”

Size Distribution of Ambient Particulate Matter and Its Constituent Chemical Species Involving Saccharides During Early Summer in a Chinese Megacity

“…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).…”
