“…In other Asian cities, relatively low concentrations levels of PAHs have been observed in Japan [ 137 , 138 , 139 ], South Korea [ 140 , 141 ], Vietnam [ 142 ], Singapore [ 143 ], Malaysia [ 144 ], Thailand [ 145 ], Qatar [ 146 ], and Lebanon [ 147 ], ranging from 0.56 ng/m 3 (Doha, Qatar) to 29.5 ng/m 3 (Gwangju, South Korea). Relatively high PAH concentration levels have been observed in Mongolia [ 148 ], Pakistan [ 149 ], India [ 150 , 151 , 152 ], and Iran [ 153 , 154 ] ranging from 0.66 ng/m 3 (Bushehr, Iran) to 773 ng/m 3 (Ulaanbaatar, Mongolia), which countries are the most polluted areas in the world. In Mongolia, wood and biomass burning for cooking and heating were the largest emission sources of PM-bound PAHs in the winter [ 148 ], while in India and Iran, traffic emission was the main contributor for PM-bound PAHs through the years [ 151 , 153 ].…”

“…Moreover, due to the special location, frequent recirculation of air masses resulted in the increased residence time of PM in Iran and lead to high air pollutants levels [156]. [109,115,127,131,146,149,152], the concentrations of PM 2.5 -bound PAHs accounted for approximately 65%~95% of the total PM-bound PAHs, proving that PAHs mostly occur in PM with a small size, which is consistent with previous studies reporting that the adsorption of PAHs depends on the PM type [69]. Although high outdoor concentrations of PM-bound PAHs were observed in certain cities, they were not as high as the personal exposure concentrations for seafarers and kitchen workers nor the indoor concentrations observed in ships and Chinese kitchens [83,84].…”

Particulate matter (PM) is a major factor contributing to air quality deterioration that enters the atmosphere as a consequence of various natural and anthropogenic activities. In PM, polycyclic aromatic hydrocarbons (PAHs) represent a class of organic chemicals with at least two aromatic rings that are mainly directly emitted via the incomplete combustion of various organic materials. Numerous toxicological and epidemiological studies have proven adverse links between exposure to particulate matter-bound (PM-bound) PAHs and human health due to their carcinogenicity and mutagenicity. Among human exposure routes, inhalation is the main pathway regarding PM-bound PAHs in the atmosphere. Moreover, the concentrations of PM-bound PAHs differ among people, microenvironments and areas. Hence, understanding the behaviour of PM-bound PAHs in the atmosphere is crucial. However, because current techniques hardly monitor PAHs in real-time, timely feedback on PAHs including the characteristics of their concentration and composition, is not obtained via real-time analysis methods. Therefore, in this review, we summarize personal exposure, and indoor and outdoor PM-bound PAH concentrations for different participants, spaces, and cities worldwide in recent years. The main aims are to clarify the characteristics of PM-bound PAHs under different exposure conditions, in addition to the health effects and assessment methods of PAHs.

“…OP describes the inherent ability of particles and their components to induce ROS generation which is an important underlying mechanism for particle toxicity. Therefore, in present study, oxidative potential (OP) of PM 10 and PM 2.5 samples along with predominantly found microbial species in urban and rural indoor environments were measured by cell free assay i.e., DTT assay and detail methodology for this assay is provided in our earlier publication (Roy et al, 2019).…”

“…Polycyclic aromatic hydrocarbons (PAHs) are a class of organic compounds containing two or more fused rings of carbon and hydrogen atoms, and represent ubiquitous contaminants in the environment [9]. These compounds are generated mainly from anthropogenic sources, such as fossil-fuel burning, coal production, oil manufacturing, oil spills, wood preservation, tobacco smoke, various forms of cooking, and occasionally from natural sources such as volcanoes and forest fires [10,11].…”

Photocatalytic Degradation of Polycyclic Aromatic Hydrocarbons in Fine Particulate Matter (PM2.5) Collected on TiO2-Supporting Quartz Fibre Filters

et al. 2021

Airborne fine particulate matter (PM2.5) pollution is known to have adverse effects on human health, and owing to their carcinogenic and mutagenic nature, polycyclic aromatic hydrocarbons (PAHs) are of particular concern. This study investigated the effect of ultraviolet (UV)-induced photocatalysis on the degradation of PAHs in PM2.5, employing titanium dioxide (TiO2)-supporting quartz fibre filters. A TiO2 layer was formed on the quartz fibre filters, and airborne PM2.5 was collected using an air sample at a flow rate of 500 L/min for 24 h. The PM2.5 samples were subsequently irradiated with ultraviolet rays at 1.1 mW/cm2. The amounts of nine targeted PAHs (phenanthrene, PHE; anthracene, ANT; pyrene, PYR; benzo[a]anthracene, BaA; chrysene, CHR; benzo[b]fluoranthene, BbF; benzo[k]fluoranthene, BkF; benzo[a]pyrene, BaP; and benzo[g,h,i]perylene, BgP) gradually decreased during the treatment, with half-lives ranging from 18 h (PHE) to 3 h (BaP), and a significantly greater reduction was found in comparison with the PAHs collected in the control (non-TiO2 coated) quartz fibre filters. However, the degradation rates were much faster when the PAHs were in direct contact with the TiO2 layer. As PM2.5 is a mixture of various kinds of solids, co-existing components can be a rate-determining factor in the UV-induced degradation of PAHs. This was demonstrated by a remarkable increase in degradation rates following the removal of co-existing salts from the PM2.5 using water treatment.
