- Urbanization is accompanied by a series of potential issues, among which the urban heat island (UHI) effect is a major concern. While urban ventilation corridors play a crucial role in addressing the UHI effect and fine particulate matter (PM) pollution, research on the diffusion mechanism of PM-bound compounds are limited, especially those of per- and polyfluoroalkyl substances (PFAS). In this work, we analyze the levels of 67 PFAS in PM along urban ventilation corridors, and utilize air-mass reaction trajectories to study their transport mechanisms. Overall, 23 PFAS involved in atmospheric transport were identified at meteorological stations. The median ΣPFAS concentration in the cold season (274 pg/m) was significantly higher than that in the warm season (114 pg/m), with trifluoroacetic acid (TFA) being the dominant homologue. Emissions from traditional fluorochemical industries and the use of fluorinated alternatives represented the main sources. Interesting, during the cold season (when prevailing northwesterly winds occur), a marked increase in PM-bound PFAS level was measured at the northwest corner. Trajectory models and potential source contribution functions revealed that high-altitude mountainous terrain in the northwest prevents wind from entering the city. Meanwhile, changes in air pressure led to southeasterly winds, which could carry TFA and PM northwestward along urban ventilation corridors, contributing 24-45% and 35-38% of the total mass, respectively. This study provides the first insight into the impact of urban ventilation corridors on the migration of particulate PFAS, which is of great significance for understanding local PFAS transport, not release, among urban clusters. - Source: PubMed

He AnenLi FeifeiLi JuanSun FanghanFang HanSun XuGuo YanliWang HailinWang YaweiJiang Guibin - Chlorinated paraffins (CPs) and environmental persistent free radicals (EPFRs) are classes of emerging organic pollutants with adverse health and environmental impacts. In this study, we investigated the occurrence, sources, environmental determinants, and health risks associated with CPs and EPFRs in PM collected from Shijiazhuang, China. The results demonstrated the ubiquity of both CPs (primarily SCCPs and MCCPs) and EPFRs in PM, with concentrations ranging from 3.48 × 10 to 3.89 × 10 pg/m and from 1.03 × 10 to 6.11 × 10 spins/m, respectively. Source apportionment revealed that CPs primarily originated from CP-related products, industrial emissions, and vehicular emissions, whereas EPFRs were mainly attributed to atmospheric oxidation and vehicle emissions. The concentrations of CPs and EPFRs were positively associated with PM, CO, and NO and negatively associated with relative humidity. Health risk assessments indicated that children (<6 years) and adults (≥18 years) exhibited higher inhalation exposure levels to both CPs and EPFRs. Notably, individuals aged 18-59 years showed the highest cigarette equivalent inhalation exposure to EPFRs, with average values of 0.285 (head airway), 0.030 (tracheobronchial region), and 0.063 (alveolar region). These findings provide valuable scientific insights for formulating targeted control strategies and public health interventions to mitigate the health risk of these pollutants globally. - Source: PubMed

Duan ShulingYan WenyanYang XuYang FanFang KeLiu JuanYao QiaoDong XiaoyanLi NaWang MengyaoXiao JiajunWang XiaonaLong KekeSun YibinCui HongyangWang QinWan YiZhang RongLiu FobangWang ChaoTang Song - The Qinghai-Tibet Plateau is known to preferentially accumulate persistent organic pollutants (POPs), largely through cold trapping. However, vegetation filtering may also substantially contribute to POP retention given the plateau's extensive vegetation coverage. To elucidate the mechanisms governing POP distributions across plateau zones, this study analyzed 208 PCB congeners in soils and seasonal air samples along a 1000-km transect from the Sichuan Basin to the Qinghai-Tibet Plateau, covering basin, forest, shrub, meadow, and sparse grassland zones. Total PCB concentrations ranged from 69.3 to 708 pg/g in soils and from 2.9 to 30.4 pg/m in air. Low-chlorinated congeners (1-3 Cl) dominated in both soils (mean 71.3%) and air (mean 58.8%). A quantitative assessment of soil-air exchange based on fugacity fractions and flux calculations indicated that plateau soils have developed secondary-source characteristics for low-chlorinated PCBs, while remaining near equilibrium or acting as weak sinks for some higher-chlorinated congeners. Along the transect, the relative contributions of vegetation filtering and cold trapping shifted from 84.7% and 15.3% in the subalpine forest zone to 34.4% and 65.6% in the plateau frigid sparse grass zone. Analysis limited to the 24 commonly monitored congeners yielded misleading mechanistic attribution, with an apparent dominance of cold trapping (85.5%-99.7%) across Zones II-V, highlighting the necessity of full-congener analysis for accurately identifying the controlling mechanisms. These results demonstrate a systematic shift in the relative roles of vegetation filtering and cold trapping across ecological zones, providing a refined, mechanism-based framework for interpreting POP distributions in cold, vegetated background regions. - Source: PubMed

Ma ChengyouDing YangLi JunChen WeiSun KaifengHuang HuanfangQi Shihua - The levels, profiles, sources, and health risks of polycyclic aromatic hydrocarbons (PAHs), nitrated PAHs (NPAHs), and oxygenated PAHs (OPAHs) were investigated in Pohang, a major iron and steel industrial city in South Korea. Passive air samplers (PASs) were deployed at 26 sites across port, industrial, and urban areas during winter for a 72-day sampling period. The mean concentrations of 21 PAHs, 17 NPAHs, and 9 OPAHs were 54.6 ng/m, 530 pg/m, and 4.8 ng/m, respectively. The mean PAH concentration at the port area was 3.9 times higher than that in other areas, primarily due to emissions from steel production processes (e.g., sintering and blast furnaces) and ship and truck activities related to cargo handling. Among NPAHs, 1-nitropyrene, a marker of diesel exhaust, was predominant at the port sites, highlighting the contribution of traffic emissions. OPAHs showed a spatial distribution similar to that of PAHs, with 9-fluorenone being the most abundant compound. Correlation analysis, diagnostic ratios, and principal component analysis revealed the influence of primary emission sources, including iron and steel manufacturing, diesel exhaust, and coal combustion, as well as contributions from secondary formation. Cancer risk assessments indicated elevated health risks in the port area, with PAHs being the major contributors. Overall, PAH and N/OPAH levels were largely driven by primary emissions in the port area, while secondary formation played a more significant role in the urban areas. This study is the first in South Korea to report atmospheric levels of both NPAHs and OPAHs using PASs. - Source: PubMed

Go MinjiLee Ho-YoungJu Jeong-TaeHong SeongjinChoi Sung-Deuk - Per- and polyfluoroalkyl substances (PFAS) in atmospheric particulate matter remain poorly characterised at large spatial and temporal scales. This study investigated the spatiotemporal distribution, long-range transport and source contributions of both legacy and emerging PFAS in PM across eastern China. A total of 540 PM samples from ten cities in Zhejiang Province (2020-2023) were analysed. Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) trajectory modelling and positive matrix factorization (PMF) identified potential source regions and contributions. Total PFAS concentrations (∑PFAS) ranged from 9.1 to 12,264.6 pg/m, with a median of 64.9 pg/m. Perfluorooctanoic acid (PFOA) was the predominant PFAS (median 21.7 pg/m), whereas hexafluoropropylene oxide dimer acid (GenX) exhibited the highest median concentration (3.2 pg/m) among emerging PFAS. ∑PFAS levels in northeastern inland cities were higher in summer than in winter, likely due to southwesterly transport from a nearby fluorochemical industrial park. Seasonal variability in PFAS was also influenced by precursor oxidation, as evidenced by positive correlations between secondary organic carbon and selected perfluoroalkyl carboxylic acids. PMF analysis identified fluorochemical production as the dominant source in inland areas, while sea spray aerosol contributed substantially to coastal regions. Interannual trends showed declining legacy PFAS but increasing detection frequencies and concentrations of alternatives (e.g., GenX, 6:2 fluorotelomer sulphonate). Additional emerging PFAS were detected through suspect screening near the industrial area, indicating growing compositional complexity. Overall, these results emphasise the continued impact of fluorochemical industrial emissions on atmospheric PFAS and the ongoing transition in PFAS profiles from legacy to emerging compounds in particulate matter. - Source: PubMed
