“…Three PAHs and derivatives, including 2-naphthylamine (a nitrogenated PAH), 9-fluorenone (an oxygenated PAH), and triphenylene (an emerging PAH), were mainly found in the samples from Jiangsu Province, which is in the YRD economic development zone. In a previous study, legacy PAH emissions in 2019 were higher in Jiangsu Province than the average for China, and the main sources were domestic coal and gasoline combustion . The correlation analysis results indicated that the concentrations of the three PAHs and derivatives in the samples from Jiangsu Province positively correlated with the concentrations of the legacy PAHs we identified (Figure S6).…”

“…In this study by Ma et al, a national-scale cancer risk assessment with atmospheric PAHs showed that BaPeq was 8.45 ± 14.1 ng/m 3 , which was higher than the new ambient air quality standards of China (GB 3095–2012, 1 ng/m 3 ) [ 18 ]. Zhang et al reported the emissions and their associated health risks of 16 priority-controlled PAHs in Jiangsu Province, and the results showed that the estimated cancer risks for different population groups were between 10 −6 and 10 −5 , indicating high potential carcinogenic risks [ 19 ]. However, studies using BaPeq and cancer risks to directly assess the human health effects of PAHs from residential solid fuel combustion have rarely been reported, especially those covering both gas and particulate phase PAHs.…”

Air pollutants from the incomplete combustion of rural solid fuels are seriously harmful to both air quality and human health. To quantify the health effects of different fuel–stove combinations, gas and particle partitioning of twenty-nine species of polycyclic aromatic hydrocarbons (PAHs) emitted from seven fuel–stove combinations were examined in this study, and the benzo (a) pyrene toxicity equivalent (BaPeq) and cancer risks were estimated accordingly. The results showed that the gas phase PAHs (accounting for 68–78% of the total PAHs) had higher emission factors (EFs) than particulate ones. For all combustion combinations, pPAHs accounted for the highest proportion (84.5% to 99.3%) in both the gas and particulate phases, followed by aPAHs (0.63–14.7%), while the proportions of nPAHs and oPAHs were much lower (2–4 orders of magnitude) than pPAHs. For BaPeq, particulate phase PAHs dominated the BaPeq rather than gas ones, which may be due to the greater abundance of 5-ring particle PAHs. Gas and particle pPAHs were both predominant in the BaPeq, with proportions of 95.2–98.6% for all combustion combinations. Cancer risk results showed a descending order of bituminous coal combustion (0.003–0.05), biomass burning (0.002–0.01), and clean briquette coal combustion (10−5–0.001), indicating that local residents caused a severe health threat by solid fuel combustion (the threshold: 10−4). The results also highlighted that clean briquette coal could reduce cancer risks by 1–2 orders of magnitude compared to bulk coal and biomass. For oPAH, BcdPQ (6H-benzo(c,d)pyrene-6-one) had the highest cancer risk, ranging from 4.83 × 10−5 to 2.45 × 10−4, which were even higher than the total of aPAHs and nPAHs. The dramatically high toxicity and cancer risk of PAHs from solid fuel combustion strengthened the necessity and urgency of clean heating innovation in Guanzhong Plain and in similar places.
