Investigation of PM2.5-bound Polycyclic aromatic hydrocarbons (PAHs) and their derivatives (nitrated-PAHs and oxygenated-PAHs) in the roadside environment at the eastern coastal region of China: characterization, source identification, and toxicity evaluation
AbstractPM2.5 samples were simultaneously collected in the urban and suburban roadside environments during different traffic flow periods at Qingdao, a coastal city located in China. The composition, diurnal variation, sources, and toxicity of PAHs, NPAHs, and OPAHs in PM2.5 were analyzed to discuss the influence of vehicle emissions on the pollution characteristics of these components. The concentrations of PAHs, NPAHs, and OPAHs in the suburban site were slightly higher than those at the urban site, and the concentrations in winter were about four times higher than those in summer. For PAHs and NPAHs, in urban site, morn...

Comparison of characteristics and sources of water-soluble inorganic ions, trace elements, and polycyclic aromatic hydrocarbons in PM2.5 on polluted and normal days in Ulsan, South Korea
AbstractPM2.5 samples were collected from a semi-rural site in the industrial city of Ulsan, South Korea during 2018 –2019 to characterize the chemical composition and determine source contributions on polluted and normal days. The daily PM2.5 concentration exceeded the United States National Ambient Air Quality Standards (35 µg/m3) on 11 of the 56 days. The mean concentration of Σ9 water-soluble inorganic ions (WSIIs) was 17.1 and 6.07 µg/m3 on polluted and normal days, respectively, with SO42 –, NO3–, and NH4+ the dominant species. The elements were dominated by Mg and Fe, with a mean concentration of Σ11 eleme...

Oxidative stress and chemical characteristics of indoor PM2.5: a case study in an underground (-3rd) floor
AbstractMany studies have examined the associations between exposure to indoor and outdoor atmospheric particulate matter and health outcomes in humans. There is increasing evidence that the oxidative characteristics of such particulate matter have a role in determining the adverse health effects of fine particulates. Moreover, since people spend more time in indoors (office and home), indoor air quality and its impact on human health have increased in importance. However, to date, studies examining the oxidative characteristics of indoor particulates are few, and there has been a limited examination of the impact on physi...

Characterization of airborne gaseous BTEX and aldehydes from populated Brazilian cities as representative atmospheres of typical urban areas from the Southern Hemisphere
AbstractThis work evaluated BTEX, HCHO, and CH3COH concentrations in the 5 most populated Brazilian urban centers. We investigated contributing sources in both dry and rainy periods, together with the ozone formation potential (OFP) and the possibly related health risk. Six simultaneous campaigns by passive sampling were carried out from August/2017 to June/2018, for periods of 14 days. The compounds were quantified by GC-FID (BTEX) and HPLC–UV/Vis (aldehydes). Atmospheric concentrations varied within 0.97 μg m−3 (m, p-xylene) to 28 μg m−3 (benzene). The HCHO and CH3COH concentration levels exceeded internat...

Comparison between oxidative potentials measured of water-soluble components in ambient air PM1 and PM2.5 of Tehran, Iran
AbstractEpidemiological studies suggest that measuring the oxidation potential of particles is more appropriate than measuring PM mass concentration. For the quantification of oxidation potential (OP) associated with ambient particulate matter (PM), two cell-based and cell-free methods are commonly used. One of the most widely used cell-free methods for particle oxidation potential is the dithiothreitol (DTT, HSCH2 (CH (OH))2 CH2SH)), which requires less controlled environments and offers faster readout of PM oxidative potential. In the present study, to observe the seasonal variations of the OP of the particulate matter o...

Observing the response of environmental and economic performances to tourism in light of structural changes
AbstractIn the current study, we explored the asymmetric impact of structural changes and tourism activities on economic performance and carbon emissions in selected economies of the Asian region from 1995 to 2020. Our findings say that the long-run estimates of positive shock in tourism are positively significant in China and India. Conversely, the estimated coefficient of negative shock in tourism is positive and significant in India only. These results confer that a rise in tourism activities causes economic growth to rise in China and India, whereas a fall in tourism activities causes economic activities to fall in Ind...

Evaluation of 213-nm laser as an affordable alternative for the green elemental characterization of particulate matter on quartz fibre filters by laser ablation ICPMS
AbstractAirborne particles, denoted as particulate matter (PM), are one of major environmental pollutants. Particles smaller than 10 µm (PM10) penetrate into the human lungs during breathing and exert damage by physical and chemical mechanisms. PM mass concentration in the air and major toxicants contained are thus regulated by relevant directives all around the world, and their continuous monitoring is prescribed. Elemental composition of PM is one of the most often measured air-quality parameters, and the standard method for its determination produces huge amounts of toxic chemical waste. Sustainable alternatives are ...
