Summary: By quantifying the concentrations of PAHs in road environmental samples from Harbin, it was found that PAHs were prevalent and had a certain health impact on local citizens. The total concentrations of PAHs in road dust, green belt soil, and parking lot dust samples varied, with high molecular weight PAHs dominating the composition. Underground parking lots had higher concentrations of PAHs compared to surface parking lots.

Summary: Road dust resuspension in urban environments can be a source of pollutants and transport them across different environmental compartments, posing a potential threat to human health. A sampling campaign was conducted in typical Portuguese cities to analyze road dust and assess its chemical composition. The results showed that road dust had high concentrations of traffic-related elements and organic compounds, including plasticizers. The concentration of priority polycyclic aromatic hydrocarbons (PAHs) varied significantly between sampling spots, and samples from harbour and commercial areas exhibited the highest toxicity.

Summary: This study investigated the presence and potential carcinogenic risk of polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (OPAHs) in indoor dust in Guangzhou City, China. The PAHs concentrations ranged from 1761 to 14,290 ng/g, with 4-6 ring PAHs being the most dominant. The OPAHs concentrations ranged from 250 to 5160 ng/g, with anthraquinone (AQ) being the main OPAHs.

Summary: The study found that levels of PAHs and Me-PAHs in workplace dust were higher than in common household and road dust, with significant contribution from aryl hydrocarbon receptor agonists. While sulfuric acid treatment reduced bioassay responses of pollutant extracts, there were still unacceptable cancer risks present, indicating the importance of considering in vitro toxic activity in environmental risk assessment.

Summary: This study analyzed the concentration, sources, and health risks of polycyclic aromatic hydrocarbons (PAHs) in paddy grain in Thailand and Laos. The main source of PAHs was found to be incomplete combustion of petroleum products, such as industrial fuels and vehicle exhausts. Agricultural waste burning and transportation emissions were identified as the main sources of PAHs. The study also indicated that the cancer risk levels from ingestion and dermal exposure were within acceptable limits in both countries.

Summary: The lunar dust problem arose from NASA's Apollo missions in 1969, as exposure to lunar dust became unavoidable. Several astronauts suffered allergy-like symptoms due to lunar dust inhalation. Research into the toxic effects of lunar dust gained significant interest and expanded to include other organ systems. With plans for future moon missions and potentially Mars missions, dust mitigation strategies are crucial for sustainable space exploration.

Summary: This study investigated the spatial and seasonal distribution, sources, and associated health risks of polycyclic aromatic hydrocarbons (PAHs) in road dust sampled from ten traffic intersections in a model African city. The study found that concentrations of PAHs in road dust fluctuated and varied significantly between seasons. The study also identified the major sources of PAHs and assessed the cancer risks for children and adults in the city.

Summary: This study found that the levels of PAHs in corals are influenced by the pollution in the surrounding environment and the morphology of the corals, with mucus containing the highest PAH loadings. Gasoline/diesel emissions, oil spills, coal combustion, and wood combustion were identified as the main sources of PAHs.

Summary: This study aimed to investigate the concentrations, sources, and health risks of PAHs in urban road dust in Shanghai, China. Results showed that 4-5 ring PAHs were predominant in road dust, with main sources being motor vehicular emissions, natural gas, and coal combustion. The carcinogenic potency was mainly contributed by four DBP isomers, and the ILCR assessment suggested a low carcinogenic risk level for both children and adults in Shanghai exposed to dust-bound PAHs.

Summary: In this study, industry-specific emission profiles of PM2.5-bound PAHs were established, and the sources were determined qualitatively and quantitatively using diagnostic ratio method and positive matrix factorization method. The results showed that heavy oil combustion, coal and natural gas combustion, vehicle emissions, steel industry emissions, and tar volatilization were the main sources of PM2.5-bound PAHs near the industrial park. The contribution of each source to potential health risk did not correspond to their mass contribution to ambient PAHs.

Summary: This study investigates the relationship between the concentration of polycyclic aromatic hydrocarbons (PAHs) in Araucaria heterophylla needles and different emission sources and road characteristics in the urban areas of Quito, Ecuador. The results indicate that non-traffic related emission sources and road characteristics play an important role in PAH emissions.

Summary: This study investigated the levels of polycyclic aromatic hydrocarbons (PAHs) in urban road dust samples from Lower and Upper Silesia regions in Poland, as well as their possible sources and potential risks. The results showed high levels of PAHs in the collected dust samples, many of which exhibited mutagenic effects and potential carcinogenic risks. This suggests that urban road dust may have adverse health effects on humans.

Summary: This study focuses on the particulates-bound PAHs in the Songshan Lake Science and Technology Industrial Park in Dongguan, China, and their impact on cancer risk and cellular toxicity. The research reveals significant differences in PAHs concentrations between summer and winter, with higher cancer risks found in the adolescent group. Results from experiments conducted on human bronchial epithelial cells indicate that PAHs can increase the formation of ROS, induce DNA damage, and affect protein levels. Stable carbon isotope ratio analysis confirms that petroleum and fossil fuel combustion are major sources of PAHs. These findings highlight the importance of particulates-bound PAHs and suggest the need to develop alternative energy sources to reduce fossil fuel combustion.

Summary: In recent years, there has been growing attention to the determination of polycyclic aromatic hydrocarbons (PAHs) derivatives containing oxygen, nitrogen, or sulfur in different environmental matrices. Their increased toxicity and sources highlight their importance in the environment. Studies have found that nitrogen-containing PAHs are more vulnerable to photooxidation, and the detection of O- and N-PAHs in airborne particles accounts for a significant portion of total mutagenicity.
