Summary: This study characterizes the spatial distribution of metals and PAHs in vegetated road shoulders with diffuse inflow of runoff in the Paris region. Copper and zinc contamination is mainly restricted to the first 30 cm from the road, while lead contamination is moderate and relatively uniform across the width of the shoulders. Highest PAH concentrations are found further from the road, likely due to different dispersion mechanisms. Copper and zinc concentrations correlate well with traffic density, while lead and PAHs do not exhibit such dependence.

Summary: This study focused on the oxidation of coal tar pitch (CTP) and its impact on polycyclic aromatic hydrocarbons (PAHs) emission during co-carbonization with coal. The results showed that oxidation reduced small and medium-molecule aromatic substances while increasing the content of macromolecules. Catalysis played a key role in facilitating dehydrogenation and condensation reactions, leading to a decrease in PAHs emissions.

Summary: This study investigated the effectiveness of the alkylation method in reducing the toxicity of coal-tar pitch (CTP). By optimizing the reaction conditions and using model compounds, the modified CTP (MCTP) showed a significant decrease in the content of toxic polycyclic aromatic hydrocarbons (PAHs). The toxicity of the MCTP was assessed through chemical index, fumes, and water-soluble substances. The results demonstrated that the alkylation method was effective in reducing the toxicity of CTP.

Summary: The yield and composition of the tar collected during a three-day gasification test of a large coal block with oxygen in atmospheric pressure conditions were investigated. Sand was used as an insulating material and the tar was sampled every 7 hours. The results showed that the composition and amount of the obtained process gas and tar were significantly affected by the reaction between the water in the wet sand and the gasified coal. The total yield of the tar from this underground coal gasification (UCG) process was 1.8%, which was three times lower than the efficiency of the classic coking process.

Summary: Traditional stormwater management in cities uses centralized systems, but there has been a shift towards decentralized management with techniques like permeable pavements. Monitoring data analysis has shown that the ceramic permeable pavement can effectively reduce peak runoff rates and the volume of water conducted downstream, demonstrating good water treatment and runoff management performance.

Summary: This study conducted a comprehensive bibliometric analysis and systematic review on the field of permeable pavement systems (PPS). The results showed that slight modifications or the incorporation of innovative filters in PPS layers can improve contaminant removal efficiency. Impermeable soils and PPS pore size are the main limiting factors for permeability and infiltration rates. Various maintenance procedures can effectively mitigate clogging effects in the upper layers of PPS. Partial replacement of PPS mix design with recycled aggregates improves permeability but slightly compromises compressive strength. The study also discusses evolving aspects for water quality improvements and future research directions in the field of PPS.

Summary: By analyzing the concentrations and compositions of PAHs and OH-PAHs in human fingernails, it was found that e-waste dismantling workers had higher exposure to these harmful substances compared to child residents. Additionally, a significant correlation was observed between the concentration of 3-OH-Flu and 2-OH-Phe in fingernails and urine.

Summary: Road runoff contributes to water pollution, particularly through sediment load. The particle size distribution (PSD) of sediment is important for selecting stormwater control measures (SCMs) and determining treatment processes required for sediment removal. Monitoring in Ohio, USA, showed that different factors, such as dry period, rainfall intensity, and windblown dust, contribute to variations in sediment characteristics in runoff. The study found that dry detention basins and wet ponds/wetlands are effective for a variety of PSDs, while hydrodynamic separators and high-flow media filters are better suited for areas with coarser PSDs, such as low density residential areas.

Summary: This study compares the hydrological changes in watershed-scale runoff before and after the implementation of green infrastructure (GI) retrofits, and finds that the GI retrofits have successfully mitigated peak flow rates. However, additional infrastructure improvement projects may have neutralized the volume reductions. Further research is needed to optimize the location, consider climate change impacts, and improve the design, construction, and maintenance of GI in urban areas.

Summary: Pervious pavement system is a suitable alternative technique for mitigating urban flooding and urban heat island simultaneously. However, the existing research primarily focuses on permeability and neglects the evaporative cooling performance, calling for further investigation on the synergistic effects of permeability and evaporative cooling in pervious pavement system.

Summary: Developing flood resilience in rapidly urbanizing cities of the Global South, such as Ahmedabad in India, is a challenging task. This study integrates a hydrodynamic model and remote sensing datasets to assess the efficacy of Green Infrastructure (GI) in managing urban stormwater. The results show that permeable pavements are the most efficient GI measure, but their benefits are marginal, highlighting the need for location-specific GI solutions in urban flood risk management.

Summary: This study monitored three field sites in Taipei city, Taiwan, and found that the water retention rate is influenced by infiltration capacity and rainfall intensity. The water retention rate at each site almost reached 50% when the cumulative rainfall was lower than 20 mm, and decreased to 40% at 60 mm rainfall.

Summary: Improved analytical methods have allowed the quantification of numerous pesticide transformation products in aquatic environments, yet there is limited understanding of their occurrence and potential toxicity. Through analyzing samples from 442 small streams in urban basins across the United States, it was found that transformation products were detected nearly as frequently as parent pesticides. Detection of these transformation products during baseflow conditions suggests chronic exposure of aquatic organisms and potential groundwater sources.

Summary: Neonicotinoid mixtures are commonly found in streams worldwide, but their ecological impacts are not well understood. This study shows that exposure to neonicotinoids above certain thresholds can lead to a loss in taxa abundance and richness, disrupted adult emergence, and altered trophodynamics. The presence of neonicotinoid mixtures in California streams also poses greater than expected risks to stream health.
