Summary: This study monitored the levels of PAHs and PBDEs in urban road dust in Tianjin, China, and assessed the health risks to the local population. The findings showed that PAHs and PBDEs posed higher health risks to children than adults. Petroleum, petroleum combustion, and biomass/coal combustion were identified as major sources of PAHs, while BDE209 was the dominant PBDE congener.

Summary: Analysis of PAHs in intertidal sediments of the Pearl River Estuary in China revealed that petroleum combustion and biomass/coal combustion are the main sources contributing to 52.78% and 40.53% of PAHs, respectively. Adverse biological effects have increased by 8% due to PAH contamination in intertidal sediments.

Summary: This study investigated the spatiotemporal distribution, source, and ecological risk of PAHs and SPAHs in surface sediments in Laizhou Bay. The results showed seasonal differences in concentrations of PAHs and SPAHs and a spatial distribution trend of estuary > coast > offshore. Combustion sources, including petroleum, coal, and biomass, were identified as the main contributors to PAHs and SPAHs. The risk level of PAHs was low-to-moderate, while SPAHs posed a moderate-to-high ecological risk.

Summary: This study investigated the occurrence, potential sources, and health risks of polycyclic aromatic hydrocarbons (PAHs) in indoor dust from households in Vojvodina, Serbia. Results indicated that PAHs from pyrogenic sources, such as vehicle emissions and wood combustion, were the dominant sources in the analyzed samples. Health risk assessment revealed that 85% of the studied locations had a total cancer risk for indoor dust exceeding the level of high concern.

Summary: The study identified seasonal variation, possible sources and health risks of 16 PAHs in street dust in Chengdu. Results showed that the primary sources of PAHs were petroleum combustion and combustion of biomass and coal. The highest cancer risk was observed in traffic areas, followed by commercial areas, educational areas, residential areas, and park areas.

Summary: This research aimed to determine the seasonal variation, distribution, potential health risks, and sources of 16 PAHs in the surface dust of eight urban areas in Qom. The results showed significant differences in the levels of PAHs at different sites and seasons, with a higher potential cancer risk for children.

Summary: This study investigates the pollution status and transport mechanisms of fine particle-bound polycyclic aromatic hydrocarbons (PAHs) in indoor and outdoor environments. The results show that the concentrations of PAHs are higher indoors than outdoors, particularly in smoking households. Additionally, the particle size distribution indicates that indoor particles are smaller in size and the sources of PAHs are mixed, originating from both local and neighboring provinces.

Summary: This study determined the levels of PM2.5, PAHs, and NPAHs in Singapore from 2020 to 2021. The results showed a slightly higher concentration of PM2.5 compared to 2015, while the average PAH concentration decreased during the sampling period. NPAHs were detected for the first time in Singapore, and PAHs and NPAHs were mainly attributed to local vehicle emissions. Air masses from Indonesia and southern China were found to potentially influence the air pollution levels in Singapore.

Summary: The pollution of microplastics (MPs) and polycyclic aromatic hydrocarbons (PAHs) in China's second largest urban lake, East Lake, was investigated. MPs were found to be more abundant in the water than in the sediment, while PAHs were mainly present in 2-3-ring PAHs in water and 4-ring PAHs in sediments. There is a strong correlation between MPs and PAHs, indicating that human activities have a significant impact on the distribution of pollutants.

Summary: This study investigates the occurrence, distribution, sources, and ecotoxicological risk of polycyclic aromatic hydrocarbons (PAHs) in sediment samples collected from three areas along the Hellenic coastline. The results reveal that Piraeus harbor is the most contaminated area, followed by Saronikos Gulf and Heraklion. Most sampling sites show evidence of combustion as the source, with petroleum contamination also indicated in Piraeus harbor. Risk assessment indicates low or no adverse health effects for exposed biota in Saronikos Gulf and Heraklion, while BaP is identified as the main contributor to carcinogenic and mutagenic risk in Piraeus harbor.

Summary: The study found a high detection rate of polycyclic aromatic hydrocarbons (PAHs) metabolites in children living in the Valencian Region of Spain, with exposure levels affected by factors such as province of residence, BMI, age, consumption of plastic-wrapped food, and dietary habits. Risk assessment showed that children's daily intake levels were within safe limits, and no potential non-cancer health risks due to PAH exposure were observed.

Summary: This study investigated the levels, spatial distribution, sources, and carcinogenic risk of 16 polycyclic aromatic hydrocarbons (PAHs) in household dust samples from China. High concentrations of PAHs were found in Northeast and Southwest China. Household fuel, cooking frequency, air conditioning, and smoking were identified as the main factors influencing PAH concentrations. Fossil combustion and biomass combustion/vehicle exhaust were the primary sources of PAHs.

Summary: This study aimed to assess the exposure of children living with hookah-smoking parents to polycyclic aromatic hydrocarbons (PAHs) using a biomonitoring approach. The findings confirmed that these children were significantly exposed to naphthalene and phenanthrene. Dietary factors and sleeping environment also influenced the exposure levels.

Summary: The presence of PAHs in parks poses a threat to human health, especially when ingested through different pathways. The environmental quality of parks directly affects the health of both tourists and residents. This study in Urumqi, Northwest China, analyzed PAHs content in park soil and common plants in eight typical parks. Results showed that PAHs content in park soil was 5-6 times higher in the summer compared to the winter, with some samples exceeding the soil pollution risk screening value. Different seasons also affected the PAHs content in plants, with tall arbors having higher PAHs content in the winter and short herbs in the summer. The source of PAHs in plants was more complex during winter. Some parks had higher levels of contamination, and the average lifetime carcinogenic risk for both adults and children reached a low-risk level in the summer, with children having a higher risk than adults.
