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 comprehensively investigated the contamination and sources of metals in urban road dust in Jinan. The results showed that winter dust had higher contamination levels compared to spring dust, with cadmium, chromium, copper, lead, antimony, tin, and zinc as the main contaminants. Industrial and traffic sources were identified as the primary contributors to metal contamination, with coal burning emissions also playing a role in winter. Industrial emissions were found to pose higher health risks due to high chromium loading factor, while traffic emissions dominated metal contamination. The noncarcinogenic and carcinogenic risks of chromium in spring and winter for children were estimated through Monte Carlo simulations.

Summary: This study evaluated the abundance of nitrogen functional genes involved in ammonia oxidation and denitrification bacteria in laboratory-scale bioretention columns. The relative abundance of ammonia-oxidizing bacteria decreased and then increased with increasing antecedent dry days, while the relative abundance of denitrifying bacteria showed a downward trend. The abundance of bacteria gene amoA was positively associated with soil ammonia nitrogen concentration and soil organic matter concentration, while the abundance of bacteria gene nirS was positively correlated with soil ammonia nitrogen, soil organic matter, and soil total nitrogen. Furthermore, gene counts for bacteria gene nirS were negatively correlated with plant root length and plant biomass. These results suggest that both nitrification and denitrification can occur in bioretention systems and are influenced by environmental factors.

Summary: The study found that the concentration of Sb in urban street dust is influenced by traffic congestion, with Sb concentrations in transportation areas significantly higher than residential and industrial areas, and significantly affected by road network density. The impact of traffic congestion on the Sb load of street dust depends on vehicle flowrate, with congestion only promoting an increase in Sb load when vehicle flowrate is high. The findings suggest that China needs to recycle brake pads and implement measures to alleviate traffic congestion and reduce brake pad wear to manage Sb emissions effectively.

Summary: This study analyzed the performance of low impact development (LID) under climate change for stormwater management. Results showed that LID practices can mitigate the impact of runoff volume, peak flow, and non-point pollution. Scenario analysis indicated a decline in LID hydraulic performance, while water quality performance varied among different climate patterns. Uncertainty analysis revealed wide-range uncertainties in LID performance due to climate change, with water quality performance being more uncertain than hydraulic performance. Spatial analysis showed spatial heterogeneity in LID performance under climate change. Sensitivity analysis suggested that climate change has a stronger impact on the short-term performance of LID practices.

Summary: This study used wavelet analysis to evaluate the effects of flow regimes of ecological water transport projects (EWTP) on ecohydrological system dynamics. The results showed that the restoration flow exhibited seasonal periodicities different from natural streams, leading to distinct groundwater dynamics and mismatched growth rhythm of riparian vegetation. Two designed flow schemes based on time lags between flow and vegetation growth were proposed to optimize the EWTP and improve ecosystem restoration efficiency. The NARX network was used for ecological restoration prediction, showing a significant increase in restoration flow compared to the original flow. The methodologies used in this study are rigorous and applicable to other EWTPs.

Summary: Investigating future flood exposure risk and associated mitigation strategies is vital for sustainable urban development. This study utilized hydrological modeling and future climate and urbanization scenarios to investigate the risk of flood exposure and the effectiveness of mitigation strategies at the city scale. The results showed that the current hydrological pattern in a highly urbanized and densely populated region in China caused a significant portion of the population and GDP to be exposed to flooding threats. Scenario analysis demonstrated that high-carbon emission scenarios increased population and GDP exposures to flood, while a green infrastructure strategy effectively decreased these exposures in low-carbon emission scenarios. Uncertainty analysis showed wide uncertainty ranges in future scenarios, and the green infrastructure strategy reduced the flood exposure uncertainty ranges. Spatial analysis indicated that population- and GDP-intensive regions were more vulnerable to flood exposure, but the effectiveness of the green infrastructure strategy was limited in these regions. The data from this study can assist in sustainable urban development in response to climate change and urbanization.
