Summary: Domestic chores, such as ironing, can significantly contribute to personal exposure to particulate matter. Chemicals released during ironing process can elevate the ultrafine particle concentrations in the air, potentially exposing individuals to harmful substances. However, the cancer risks associated with inhalation of metals and organic compounds were found to be insignificant.

Summary: Air pollution ranks fourth in terms of risks to human health, following high blood pressure, tobacco use, and poor diet. It is estimated that air pollution caused 6.67 million deaths worldwide in 2019. In the European Union, 97% of the urban population is exposed to levels of fine particulate matter that exceed the World Health Organization's latest guideline levels. Air pollution accounts for 20% of newborn deaths globally, mostly due to complications from low birth weight and preterm birth.

Summary: Aerosols are an important source of dissolved black carbon (DBC) in the ocean, and the impact of anthropogenic activities on the seasonal variations of aerosol DBC concentration and condensation degree remains unclear. In this study, we collected 33 aerosol samples from a coastal site in China and analyzed the concentrations of DBC, water-soluble organic carbon (WSOC), and elemental carbon (EC). Our results showed that DBC concentrations were higher in spring and winter, influenced by sources, rainfall frequency, and secondary processes. The dominant source of DBC was fossil fuel (FF) burning, with enhanced contribution from biomass burning brought by East Asian Monsoon.

Summary: In this study, a colorimetric ozone passive sampler (OPS) was developed to improve the recognition of average ozone (O3) exposure. By analyzing the colorimetric changes and using the effective absorbance of blue scale, the OPS was optimized and validated. Field tests showed a significant disparity between O3 concentrations and personal O3 exposures, highlighting the importance of assessing health risks. The OPS serves as a useful tool for monitoring O3 exposure levels and raising awareness of invisible indoor hazards.

Summary: This study evaluated the hemolytic activity of PM10 samples collected from coal-burning homes in Xuanwei, China, and analyzed their trace elemental contents. The results showed a positive correlation between the concentration of trace elements in PM10 samples and their hemolytic activity. Heavy metal elements, such as zinc, lead, and cesium, were found to positively correlate with hemolysis, while lithium, uranium, and vanadium negatively correlated with hemolysis. These findings suggest that heavy metal elements may be responsible for the hemolytic capacity of indoor PM10 in coal-burning environments.

Summary: The laboratory experiment found that carbonaceous aerosols from different emission sources can be activated as cloud condensation nuclei (CCN) at high supersaturations. Among the sources, combustion of cow dung cake had the fastest activation rate, followed by wood burning and DG emissions. Organic carbon was the dominant carbon component in all sources, with DG emissions having the highest BC mass concentration. Non-refractory aerosol chemical composition analysis showed organic species dominate in all emissions.

Summary: The chemical composition of PM2.5 has a significant impact on human health and air quality. Assessing and quantifying the impacts of various factors on PM2.5 chemical components can guide effective regulations to improve air quality. Generalized additive models (GAMs) were used to assess the factors affecting different PM2.5 species in the South Coast Air Basin. Results show that precursor emissions have the most significant effect on PM2.5 species production, while meteorological factors also influence PM2.5 composition. In the future, meteorological factors will become more significant in affecting PM2.5 speciation.

Summary: This study conducted a one-year aerosol sampling campaign in a suburban area of Leon city, Spain from 2016 to 2017. The research found that traffic and secondary aerosols had the highest contributions to PM10 in hybrid cyclonic types with wind components from the first and second quadrant. Additionally, the study discovered that the dust factor had the highest contributions in northerly types, and linear models built for estimating the source apportionment of PM10 were strongly correlated with PMF models.

Summary: The study in Leon, Spain aimed to characterize the physical and chemical properties of precipitation for one year. Linear models were established to predict the chemical composition of rainwater and the efficiency of the removal effect, with findings showing higher ion concentrations and conductivity in summer due to low rainfall volume. Furthermore, the study found that removal coefficients are influenced by various factors such as species concentration in the air before precipitation and the duration of the event.

Summary: The study on airborne particulate matter in two urban environments in Coimbra found that anhydrosugars from biomass burning and sugar alcohols from biological sources are significant contributors to total sugars. Higher concentrations of levoglucosan were associated with biomass-fueled heating appliances during colder periods. Fungal spores showed a significant contribution to PM10 and organic carbon mass, especially in warmer periods.

Summary: Research shows that as Saharan dust travels from the Sahara Desert to Cape Verde and Puerto Rico, the proportion of Ca-bound P decreases, while the proportion of iron/aluminum-bound P increases. Laboratory experiments suggest that these changes may be attributed to increasing degrees of particle sorting and atmospheric acidification during dust transport.

Summary: In this study, the thoracic fraction of road dust (PM10) was measured in parking areas in Portugal for the first time. The results showed that the dust loadings were higher in outdoor parking areas compared to indoor parking areas. The analysis of elemental components showed the presence of major and minor elements, with iron oxide content affecting the separation of carbonaceous content. The ecotoxicological bioassay revealed that all aqueous solutions from the parking areas were toxic to bioluminescent bacteria.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
