“…Studies have shown that an increase of 200 mg to 500 mg in cellulose content can cause an increase of 14 μg/g to 24 μg/g in EFs of PAHs during burning [ 104 ]. Moreover, the burning of biomass with a high polyunsaturated fatty acid to saturated fatty acid (PUFA/SFA) ratio can lead to high PAH emissions [ 105 , 106 ]. This is because PUFAs have more carbon–carbon double bonds than SFAs, making it easier for them to form free radicals during pyrolysis and, therefore, promoting the generation of PAHs [ 107 ].…”

To mitigate global warming and achieve carbon neutrality, biomass has become a widely used carbon-neutral energy source due to its low cost and easy availability. However, the incomplete combustion of biomass can produce polycyclic aromatic hydrocarbons (PAHs), which are harmful to human health. Moreover, increasing numbers of wildfires in many regions caused by global warming have greatly increased the emissions of PAHs from biomass burning. To effectively mitigate PAH pollution and health risks associated with biomass usage, the concentrations, compositions and influencing factors of PAH emissions from biomass burning are summarized in this review. High PAH emissions from open burning and stove burning are found, and two- to four-ring PAHs account for a higher proportion than five- and six-ring PAHs. Based on the mechanism of biomass burning, biomass with higher volatile matter, cellulose, lignin, potassium salts and moisture produces more PAHs. Moreover, burning biomass in stoves at a high temperature or with an insufficient oxygen supply can increase PAH emissions. Therefore, the formation and emission of PAHs can be reduced by pelletizing, briquetting or carbonizing biomass to increase its density and burning efficiency. This review contributes to a comprehensive understanding of PAH pollution from biomass burning, providing prospective insight for preventing air pollution and health hazards associated with carbon neutrality.

“…In China, the demand for heat-treated sunflower seed oil has increased substantially. However, researches on roasted sunflower seed oil were mainly focused on its nutritional properties, safety and physicochemical indexes but not on flavor ( Ji et al, 2022 , Kiczorowska et al, 2019 , Özcan and Köse, 2022 ; C.-X.

“…BaP in edible oil originated from various factors including the environmental pollution of raw materials, seeds drying on asphalt road surfaces, and production during the processing of edible oils (Cotugno et al, 2021). To date, peanut (Ji et al, 2020), sesame (Ji et al, 2019), olive (León-Camacho et al, 2003), and rapeseed oils (Rojo Camargo et al, 2012) have been reported to contain relatively high concentrations of BaP. Now, China has set a legal limit of 10 µg/kg for BaP content in edible oils, and the European Commission has established the maximum levels for BaP was 2 µg/kg (Ji et al, 2020;Kazerouni et al, 2001).…”

The safety problems related to the occurrence of benzo(a)pyrene in edible oil have been a major threat to human health, and now significant attention has been to remove benzo(a)pyrene. So in this work, cellulose, hemicellulose, and lignin biochars were prepared, and then were used to remove benzo(a)pyrene from contaminated oil. Based on the nitrogen adsorption/desorption isotherms and the scanning election micrographs, the modified biochars had a huge specific surface area of 983.50-1915.55 m 2 /g and a well-developed porous structure. The modified biochars showed higher removal rate for benzo(a)pyrene than unmodified biochars. The highest adsorption (95.79%) of benzo(a)pyrene was achieved using the modified lignin biochar, which was therefore selected for evaluation of adsorptive capacity. The ability of the modified lignin biochar to adsorb benzo(a)pyrene was consistent with the pseudo-second order kinetic equation indicating mainly chemisorption, and it fit the Freundlich isotherm (R 2 > 0.999), thereby revealing the occurrence of multilayer adsorption. The effect of π-π conjugation interaction and pore-filling together promoted the high adsorption performance of the modified lignin biochar. This work demonstrates that the modified lignin biochar could be a promising adsorbent for the removal of benzo(a)pyrene from edible oils.
