Summary: Air pollution caused by industrialization and modernization is considered a major threat to global health and obesity. Epidemiological studies indicate a correlation between exposure to various air pollutants and overweight/obesity. Mechanisms such as inflammation, oxidative stress, metabolic imbalance, intestinal flora disorders, and epigenetic modifications may contribute to the increased risk of obesity caused by air pollution. Macro and micro-level measures should be taken to prevent the negative effects of air pollution on obesity prevalence.

Summary: The study aimed to develop predictive regression models for indoor PM2.5 and black carbon (BC) in densely populated slums in Mumbai. The models showed moderate to good performance, with ambient PM2.5 being the most significant predictor for both pollutants. The study demonstrates that indoor particulate matter exposures can be reasonably predicted using publicly available air pollution data and information on local traffic and housing characteristics, and also underpins the high exposure to traffic pollution in urban slums.

Summary: This study investigated the relationship between indoor and outdoor air pollution and hypertension (HTN) in rural areas of eastern China and explored their potential interactions. The findings revealed a significant positive association between outdoor and indoor air pollution and HTN, as well as a significant negative association between range hood use and HTN. Additionally, outdoor air pollution was found to enhance the positive effects of indoor air pollution on HTN, while PM2.5 and O-3 reduced the protective effect of range hood use on HTN. Females were also found to be more susceptible to both indoor and outdoor air pollution.

Summary: Lockdown measures slightly reduced outdoor PM2.5 concentrations in a Malaysian suburb. Cooking during the COVID-19 lockdown led to a substantial increase in PM2.5 exposure, with an estimated 25% excess risk for health. This suggests a potential for greater exposure to fine particles indoors under lockdown.

Summary: The impact of bicycle lane designs on cyclist exposure to air pollution is a significant concern. This study found that in the city of Medellin, Colombia, the sections without dedicated bicycle lanes had the highest PM2.5 exposure and inhaled dose. Cyclists had higher PM2.5 exposure and inhaled dose during morning peak hours compared to evening peak and off-peak hours. Segregated cycling lanes on the sidewalk can considerably lower PM2.5 exposure and inhaled doses for cyclists.

Summary: This study aimed to partition and quantify indoor and outdoor-generated PM2.5 in residences using a recursive model, and compared the results with outdoor and ambient measurements. The findings suggest that ambient measurements can be used as a model input for pollution origin partitioning. The study highlights the importance of partitioning pollution for investigating health outcomes and informing targeted interventions for indoor and outdoor sources of pollution.

Summary: This study investigated the rates, product branching ratios, and stereochemistry of organosulfates from reactions of dilute IEPDX under a range of sulfate concentrations and pH values. It was found that the regiochemistry and stereochemistry of products were affected by pH, with tertiary methyltetrol sulfate promoted by increasing solution acidity. The reaction rate constants under cloud-relevant conditions were significantly lower than those reported for aerosol-relevant conditions due to different solution activities.

Summary: A study in Wilmington, NC, on the southeastern coast of the United States, found that wet deposition was more effective in removing PFAS and PFECAs from the atmosphere compared to dry deposition. The data showed a significant rainout effect, indicating that incorporation of PFAS into rainwater is a relatively local phenomenon. The study also provided evidence of PFECAs in wet and dry deposition, suggesting that particle-bound and gas-phase PFAS could be rapidly removed by raindrops.

Summary: The research demonstrates that adding common fluorinated pollutants to seawater can enhance the ice nucleation activity of simulated sea spray particles, especially in conditions relevant to cirrus cloud formation. Further studies are needed to investigate the interactions of fluorinated pollutants with other marine organic matter to determine the impacts of particle composition on the ice nucleation activity of ambient sea spray.

Summary: This study investigated the emission of PFASs during floor stripping/waxing activities and their potential occupational exposures. The study found that concentrations of five PFASs in the air were significantly higher during floor stripping/waxing compared to before, and were one order of magnitude higher than typical indoor and outdoor concentrations. These results imply that floor stripping activities may lead to occupational PFAS exposures.

Summary: While high-resolution MS is suitable for novel PFAS identification and quantification, low-resolution MS/MS is the more commonly used and affordable approach for routine PFAS monitoring. However, the interference of chemical compounds in the quantitative ion channel hinders the verification of PFPeA and PFBA on low-resolution instrumentation. Adjustments to analytical methods, such as altering LC conditions and using matched internal standards, are recommended to investigate and confirm PFBA and PFPeA detections in both biological and environmental samples.

Summary: This study examined the role of gas-phase hydroxyl radical in the heterogeneous oxidation of freshly generated IEPOX-SOA particles in the atmosphere. It was found that oligomers in IEPOX-SOA particles decompose through this reaction, maintaining a reservoir of low-volatility compounds. The study also proposed structures and formation mechanisms for previously uncharacterized SOA constituents in PM2.5, suggesting that this reaction may contribute to the atmospheric lifetimes of particle-phase IEPOX-SOA.

Summary: During the Indoor PFAS Assessment (IPA) Campaign, concentrations of nine neutral PFAS were measured in air and cotton cloth in 11 homes in North Carolina. The study found that fluorotelomer alcohols were the dominant species in indoor air, while perfluorooctane sulfonamidoethanols accumulated most significantly in cloth. Cloth-air partition coefficients were derived for different PFAS and were positively correlated with the octanol-air partition coefficient. Temperature was found to have the greatest effect on PFAS accumulation.
