Summary: Microplastics, as emerging anthropogenic stressors, pose potential threats to ecosystems and human health. While the presence of microplastics in water is well-documented, their distribution in the air is limited. This study investigates the occurrence of microplastics in suspended particulate matter in Tempe, Arizona, and finds that microplastics are present in all collected samples, ranging in concentration from 0.02 to 1.1 microplastics/m3 with sizes ranging from 5 to 5000 μm. Fibrous microplastics are the most prevalent, accounting for over 82% of the microplastics. The study also characterizes the chemical composition of the airborne microplastics using micro-Raman spectroscopy, revealing a variety of polymers, with polyvinyl chloride being the most abundant.

Summary: The distribution of miniaturized plastic particles, including microplastics and nanoplastics, in various ecosystems is a major environmental concern due to their unique properties and potential toxic effects. These particles can release toxic additives, adsorb chemicals, and pose a danger for trophic transfer to higher animals. Efforts to mitigate these impacts include understanding their sources, properties, and detrimental effects on habitats, as well as exploring self-cleaning mechanisms through saprophytic organisms.

Summary: This study investigates the distribution of microplastics in Chilika Lake, India, and finds that they mainly come from anthropogenic activities such as fishing and tourism, as well as river inflows. Fragments and foams are the most common shapes of microplastics, with sediment samples having smaller particle sizes (<1 mm) and water samples dominated by white foams in the 2-5 mm size range. Additionally, polypropylene and polystyrene are the most common types of microplastics in sediment and water samples.

Summary: This study investigated the exposure to PAHs on the Karakoram Highway in Pakistan. Results showed that HTV drivers who spent long hours in heavy traffic inhaled a significant amount of PAH carcinogens. The urinary metabolites of PAHs were higher in HTV drivers compared to the control group. Urinary benzo[a]pyrene metabolites were detected in similar amounts among HTV drivers regardless of their working hours. The study also found a smoking effect on urinary levels of certain metabolites, which were associated with the increase in driving hours per day. The elevated PAH body burden was linked to the nature of the drivers' job and the environmental pollution on the Karakoram Highway.

Summary: The structure of biochar produced at various pyrolysis temperatures has a significant impact on the behavior of metals in the soil-plant system. High pyrolysis temperatures increase the carbon-containing groups in biochar, which can adsorb metals from the soil-plant environment. Applying biochar amendments effectively decreases metal transformation in the soil-plant environment.

Summary: Geothermal resources in the southern Tibetan Plateau are rich and have significant variations in their origin, evolution, and circulation mechanism. The hydrochemical characteristics of cold springs and geothermal springs are different, with carbonate dissolution and cation exchange being the dominant processes for geothermal springs. The main carbon source for geothermal waters is deep-derived CO2, while cold springs and surface waters are primarily replenished by meteoric water. The temperature and circulation depth of geothermal waters exhibit large variations.

Summary: Data-driven models (DDMs) are increasingly popular in groundwater hydrology due to advances in machine learning algorithms and readily accessible data. This study compares deep learning (DL) algorithms to traditional tree-based machine learning (TB) algorithms for groundwater level simulation and investigates the importance of different input features. The results show that deep learning-based DDMs outperform tree-based models in terms of correlation with observed data and the encoder-decoder-LSTM model performs the best. Factors related to human activities are found to have a stronger impact on groundwater level variation. Preprocessing of driving factors is crucial for achieving satisfactory simulations in data-scarce areas.

Summary: The accurate evaluation of squeezing during the design stage can reduce technical problems and financial costs of underground structures. However, current methods for predicting tunnel squeezing have deficiencies such as site-specificity and incomplete databases. In this study, a comprehensive literature review was conducted to prepare a database of tunnel squeezing for soft rocks, and statistical processing methods were employed to improve its quality. New squeezing criteria were developed using regression methods, which were found to be more accurate than empirical equations.

Summary: Contaminant transport in fractured media poses challenges to traditional transport models due to complex dynamics and non-Fickian diffusion. In this study, a natural-gradient tracer test in a fractured carbonate aquifer in Germany showed dual peaks and positive skewness in breakthrough curves (BTCs). The fractional derivative equation (FDE) model outperformed the dual-continuum model (DCM) in capturing the heavy-tailed BTC, while the DCM model reasonably replicated the bimodal BTC. To further characterize multiple BTC peaks, a fractional derivative dual-continuum model (fDCM) was proposed.

Summary: In flood-prone areas, using advanced computer models to assess flood risk and develop informed evacuation plans is crucial for emergency responders. This study developed an integrated socio-hydrological modeling framework to examine the impact of evacuation shelter arrangement and human behaviors on household evacuation outcomes. The results demonstrate that the number and geographical distribution of shelters significantly affect the evacuation process, and strategic placement of shelters is more important than their quantity. Additionally, low heterogeneity in evacuation preparation times and individual route choices can lead to traffic congestion and reduce system-level evacuation performance.

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.

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.
