Summary: Medium-flow atmospheric samplers were used to collect particulate (PM2.5) and gaseous samples from indoor kitchens in 35 randomly selected rural houses in North China. Analysis showed that cooking with coal resulted in significantly higher PAH and NPAH concentrations compared to cooking with LPG or electricity, while the use of range hoods and proper ventilation can reduce the levels of PAH and NPAH during cooking.

Summary: Indoor concentrations of fine particulate matter (PM2.5) are highly variable, with different sources such as cooking and smoking playing a major role in contributing to elevated PM2.5 levels indoors. Renters in multifamily housing are more likely to be exposed to higher PM2.5 levels from non-ambient sources, such as cooking and smoking, compared to homeowners in single and multifamily housing. These disparities in PM2.5 exposure by homeownership can be explained by a combination of behavioral and building factors.

Summary: During the COVID-19 lockdown, indoor PM2.5 concentrations increased significantly, particularly with clear peaks in residential areas in the afternoon and evening, reflecting increased human activity and household chores during meal times. The contribution of indoor-generated PM2.5 to total indoor concentrations increased as high as 80% during and post-lockdown periods compared to before lockdown.

Summary: Fine particulate matter (PM2.5) is a severe problem in China, and the lack of ground-based measurements hinders long-term air pollution studies. This study used newly updated Global Estimates (V5.GL.02) of monthly PM2.5 data from 2001 to 2020 based on Geographically Weighted Regression (GWR) to analyze pollution hotspots and sources in China. The results showed significant PM2.5 pollution hotspots in central and northwest China, with the highest pollution levels occurring in winter.

Summary: This study investigated spatiotemporal variations and source contributions of indoor PM2.5 in a typical apartment in Beijing using low-cost sensors. It was found that indoor particulate matter predominantly originates from outdoor infiltration and cooking emissions, with the latter contributing more fine particles. Indoor PM2.5 concentrations were correlated with ambient levels but generally lower, with the predominant indoor source being cooking.

Summary: This study provides comprehensive insights into the chemical composition, source identification, and health risk assessment of indoor particulate matter (PM) in urban areas of Vietnam. The results suggest that indoor PM2.5 is mainly derived from outdoor sources, while indoor PM0.1 is derived from both indoor and outdoor sources. The study also highlights the presence of various trace elements in indoor PM, with differences in concentrations between seasons and dwelling types. Monte Carlo simulation indicates that the intake of TEs in PM2.5 can lead to high carcinogenic risk for people over 60 years old and unacceptable non-carcinogenic risks for all ages, particularly at roadside houses in winter.

Summary: The main components of PM2.5 in the soot of coal-fired power plants in Fuxin are SO42-, Ca2+, and organic carbon. The element components range from 5.06% to 10.97%, the ionic components range from 36.53% to 48.59%, and the total carbon content ranges from 9.43% to 11.36%. The source profile of PM2.5 in Fuxin coal burning smoke is mostly similar to Fushun, but not similar to Colorado.

Summary: The study found that while the total concentration of PAHs in indoor air has decreased, it remains steady in outdoor air and indoor dust. Additionally, more carcinogenic PAHs were observed in indoor/outdoor air in Asia, while in dust samples this was more prevalent in North America. Monte-Carlo simulations showed that children's exposure to indoor sources in dust and air exceeded outdoor levels.

Summary: This study conducted a wintertime field campaign in northern China to assess indoor PM2.5 variations. It was found that indoor PM2.5 concentration was about 60% lower in households using clean heating approaches compared to those burning traditional fuels. The results also showed that a transition to clean coals or biomass pellets could reduce indoor PM2.5 by 20%, and further switching to clean modern energies would reduce it an additional 30%, highlighting the significant benefits of promoting clean transitions in household heating activities.

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 association between ambient PM2.5, O3 pollution, and ovarian reserve in reproductive-aged Chinese women. The results showed that increased exposure to PM2.5 and O3 was associated with decreased AMH levels, indicating reduced ovarian reserve. Notably, the effects of O3 exposure on ovarian reserve were different from those of PM2.5 exposure.

Summary: Systemic insecticides and rising temperatures have combined effects on the abundance of Odonata nymphs in paddy fields. The standalone effect of insecticide exposure decreased the Odonata community, while nymphs decreased synergistically with temperature rise in paddy water. However, the impacts of each stressor alone varied among species.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

Summary: The synergistic effects of trace sulfadiazine and cast-iron corrosion scales on the formation of disinfection by-products in drinking water distribution systems were investigated. The presence of magnetite resulted in increased concentrations of DBPs due to the higher microbial activity and enhanced microbial extracellular electron transport pathway. The study highlights the importance of considering trace antibiotics pollution and corrosion scales in water sources for DBP control.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
