Summary: Combined sewer overflows (CSOs) are a major environmental concern, causing pollution for water bodies. Constructed wetlands (CWs) are a promising nature-based solution for CSO treatment. This study presents the first monitoring of a full-scale CSO-CW system, located in Italy, which showed high treatment efficiency for COD, TP, and N-NH4+, in line with literature data on CSO-CWs in the sewerage network. The system also provided additional ecosystem services and had low operational and maintenance costs.

Summary: Urban sewage water pathways, especially stormwater runoff and wastewater treatment plants, are significant sources of microplastics emissions to the Baltic Sea. Coastal emissions contribute around 50% of the total microplastics emissions, and reducing sewer overflow and implementing tertiary treatment at WWTPs could substantially decrease emissions to the sea.

Summary: Combined sewage overflows (CSOs) are a common consequence of heavy rainfall events and have significant implications for water quality. With climate change, these events are becoming more frequent and intense, placing greater pressure on aquatic ecosystems. To prevent water pollution, the integration of a dynamic model with rapid calibration of the event mean concentration (EMC) is essential.

Summary: Combined sewer overflows pose significant threats to public health and the environment, and various strategies have been proposed to mitigate their adverse effects. Smart control strategies have gained traction due to their cost-effectiveness but face challenges in balancing precision and computational efficiency. To address this, we propose exploring machine learning models and the inversion of neural networks for more efficient CSO prediction and optimization.

Summary: The characteristics and regulation mechanism of overflow pollution caused by sewer sediments under different precipitation intensities were investigated. The results showed that sewer sediments were the main source of overflow pollutants, contributing up to 70%. A prediction formula for the regulation and storage time of overflow pollutants was obtained based on the relationship among rainfall intensity, sediment scouring thickness, and regulation and storage time.

Summary: Combined sewer systems (CSS) are associated with higher incidences of COVID-19 cases, particularly in areas with heavy precipitation and high percentages of impervious surfaces, potentially due to increased frequency and severity of combined sewer overflows (CSOs). This finding suggests links between climate change, urbanization, and COVID-19.

Summary: Among various countermeasures against combined sewer overflow (CSO), urban green space (UGS) has been proven to be effective. However, the effects of UGS on CSO at the municipal scale have not been extensively studied. Therefore, this study aimed to develop a novel method for estimating the relationship between UGS and CSO using a case study in the Tokyo metropolitan area. The results showed that the amount of CSO increases exponentially with rainfall intensity, and increasing the proportion of UGS can mitigate CSO in all sewersheds, especially when the UGS proportion is increased from 5% to 10%.

Summary: This study investigated the dynamics of microplastics (MPs) in a newly established surface flow constructed wetland (CW) that receives 1.4 million liters per day of secondary treated wastewater. The study found that most MPs were synthetic fibers and fragments in the size range of 100-1000 micrometers. The CW effectively retained MPs, but the accumulation of MPs in sediments and substrate needs to be considered.

Summary: This study evaluates different management scenarios for combined sewer overflows (CSOs) in the European Union and United Kingdom using a large scale hydrological model. Treating CSOs before discharge is found to be more cost-effective than prevention. Among prevention strategies, urban greening has a much higher benefit/cost ratio. Real time control can also reduce CSO volume to some extent.

Summary: The A-01 wetland treatment system was designed to remove metals primarily copper from effluent, with consistent removal of Cu averaging about 80% over 20 years of operation. Most divalent metals were rapidly removed from water and held in sediments shortly after entering the treatment wetland. Highest concentrations of Cu, Pb, and Zn were found in sediment from the first cell in each pair, indicating that most of these metals in the effluent were quickly bound to the sediment.

Summary: Combined sewer overflows (CSOs) occur when untreated raw sewage mixed with rainwater, runoff, or snowmelt is released during or after a storm in any community with a combined sewer system (CSS). This study aims to provide CSS communities with tools to assess the performance of their CSS systems over time, especially in evaluating efforts to reduce CSOs. A new critical rainfall intensity threshold and a multiple linear regression model are identified and used to predict CSO incidence and volume based on rainfall event characteristics.

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.
