“…After 5 weeks of continuous operation with consistent TC data, the measured denuder efficiency was 74 %. We recommend that the denuder should be replaced or regenerated when its efficiency drops below 70 % (Ania et al, 2005;Bhagawan et al, 2015;Gao et al, 2014). The standard operating procedure for routine use of the TCA08 instrument recommends replacement or regeneration of the denuder honeycomb element once per month.…”

“…Moreover, PC can evolve even prematurely in the inert atmosphere depending on the thermal protocol used for the analysis, especially in the presence of oxygen donor substances in the sample (Sciare et al, 2003). Additionally, PC and EC have been shown to have significantly different values of σ (Bhagawan et al, 2015;Cavalli et al, 2010;Chen et al, 2015;Karanasiou et al, 2015;Subramanian et al, 2006). The σ PC is mostly affected by the composition of its organic precursors, aerosol type and duration of sampling.…”

Abstract. We present a newly developed total carbon analyzer (TCA08) and a method for online speciation of carbonaceous aerosol with a high time resolution. The total carbon content is determined by flash heating of a sample collected on a quartz-fiber filter with a time base between 20 min and 24 h. The limit of detection is approximately 0.3 µg C, which corresponds to a concentration of 0.3 µg C m−3 at a sample flow rate of 16.7 L min−1 and a 1 h sampling time base. The concentration of particulate equivalent organic carbon (OC) is determined by subtracting black carbon concentration, concurrently measured optically by an Aethalometer®, from the total carbon concentration measured by the TCA08. The combination of the TCA08 and Aethalometer (AE33) is an easy-to-deploy and low-maintenance continuous measurement technique for the high-time-resolution determination of equivalent organic and elemental carbon (EC) in different particulate matter size fractions, which avoids pyrolytic correction and the need for high-purity compressed gases. The performance of this online method relative to the standardized off-line thermo-optical OC–EC method and respective instruments was evaluated during a winter field campaign at an urban background location in Ljubljana, Slovenia. The organic-matter-to-organic-carbon ratio obtained from the comparison with an aerosol chemical speciation monitor (ACSM) was OM/OC=1.8, in the expected range.

“…This unexpected increase, especially in eBCff concentrations, after lifting of the LD was most probably derived from (i) exertions for restoring supply-chain losses, such as elevated fossil fuel consumption in transportation and industrial activities, (ii) escalated construction activities in the vicinity of the study area, (iii) more stable atmospheric conditions due to lower wind speed compared to the Post-LD phase, and (iv) long-range transport of BC particles from other regions to the receptor site. Domestic heating, burning of crop residues, and forest fires have been reported as primary sources of BC bb emissions, contributing significantly to the BC budget in other regions, such as Brazil [47], Canada [46], China [87], Finland [88], Greece [89], India [90], Italy [91], Spain [77], Turkey [41], and the USA [92]. However, wood-burning stoves in restaurants and open-air barbecues are the only eBC bb sources within the study area and most parts of the KSA, since domestic heating is provided by air conditioners/electric heaters and farms/forested lands are very scarce.…”

Black carbon (BC) particles being emitted from mobile and stationary emission sources as a result of combustion activities have significant impacts on human health and climate change. A lot of social activities have been halted during the COVID-19 lockdowns, which has evidently enhanced the ambient and indoor air quality. This paper investigates the possible emission sources and evaluates the meteorological conditions that may affect the dispersion and transport of BC locally and regionally. Ground-level equivalent BC (eBC) measurements were performed between January 2020 and July 2020 at a university campus located in Dammam city of the Kingdom of Saudi Arabia (KSA). The fossil fuel (eBCff) and biomass burning (eBCbb) fractions of total eBC (eBCt) concentrations were estimated as 84% and 16%, respectively, during the entire study period. The mean eBCbb, eBCff, and eBCt concentrations during the lockdown reduced by 14%, 24%, and 23%, respectively. The results of statistical analyses indicated that local fossil fuel burning emissions and atmospheric conditions apparently affected the observed eBC levels. Long-range potential source locations, including Iraq, Kuwait, Iran, distributed zones in the Arabian Gulf, and United Arab Emirates and regional source areas, such as the Arabian Gulf coastline of the KSA, Bahrain, and Qatar, were associated with moderate to high concentrations observed at the receptor site as a result of cluster analysis and concentration-weighted trajectory analysis methods.

“…During the past decades MT registered a significant global increase which is expected to continue over the coming decades [2] [3], leading to the increase of research on its environmental impacts (e.g. [4] [5] [6] [7] [8]. Shipping emerged as an important source of air pollution in coastal areas [5] mainly associated with the large quantities of particulate matter (PM) emitted and the consequent implications on air quality and human health.…”

Maritime transportation, widely used both in international transport of goods and touristic purposes, has been identified as a significant source of ultrafine particles (UFP). Inland passenger ferry is a source of UFP far less addressed; however, in locations with relatively high frequency of this transportation mode, it is expected that they contribute to an increase of their concentration. Moreover, the negative effects of UFP on human health and environment are known and therefore, monitoring UFP produced by ferries is vital to assess the degree of exposure of who work or live close to ferries' terminals or downwind to their cruising path. This work aims to study the influence of inland ferries activities on UFP in the urban/suburban areas near ferries' terminals and downwind across the cruising path. The UFP monitoring campaign was carried out from September to December 2018 for 19 non-consecutive periods. The sampling sites were chosen in order to maximize measurements under downwind conditions and allow the association between ferry operation and UFP concentration response. Based on data collected, correlation analysis was performed between ferry's traffic and particle number counting (PNC) of UFP, and also with meteorological variables. Results show an increase in PNC ranging from 25 to 197% during the third minute around a ferry movement and are moderate to positive significant correlations between PNC values and the number of ferry operations (r = 0.79 to r = 0.94), showing that UFP emitted by inland ferries contributes to PNC increase. Moreover, negative correlations
