Summary: Developing a green infrastructure is an important environmental policy goal in many countries around the world. Different countries have different requirements on the spatial allocation of conservation sites for green infrastructure. Price-type and procedural instruments are commonly used, but the utilization of incentive mechanisms that internalize the benefit of clustering is relatively low. There is a need for more studies on incentive mechanisms and green infrastructure policies in the global South.

Summary: This study presents a method for quantifying the benefits of reducing runoff associated with distributed green stormwater infrastructure (GSI) at the spatial scale required for urban stormwater implementation. The model, driven by a probabilistic representation of rainfall events, provides estimates on a 30-m grid, preserving unique combinations of drainage factors, hydrologic storage, and infiltration benefits of GSI. The model demonstrated strong correspondence with continuous runoff data from urbanized catchments in Salinas, California, over a three-year monitoring period and showed sensitivity to storm drain network inputs.

Summary: This study investigated the combined effects of substrate depth and vegetation on runoff reduction and airborne pollutant purification in green roofs. The results showed that increasing substrate depth significantly increased runoff reduction. Vegetated plots had slightly higher runoff reduction compared to non-vegetated plots. Vegetation acted as an effective tool to neutralize acid rain, stabilize pH, and reduce heavy metals in the runoff by remediating dissolved air pollutants from rainwater.

Summary: This study investigates the generation, degeneration, and fate of plasticrusts, which are a plastic form encrusting intertidal rocks. The researchers found that plasticrusts are mainly derived from common polyethylene containers and polyester-based paint. They also observed that wave exposure and tidal amplitude are positively related to the abundance, cover, and distribution of plasticrusts. Experiments showed that plasticrusts are generated through scratching and abrasion by cobbles, as well as movements during beach clean-ups. Monitoring results revealed a decrease in plasticrust abundance and cover over time, with detached plasticrusts contributing to microplastic pollution.

Summary: The study found that fecal indicators were measurable in both MP and wood biofilms incubated in wastewater influent, but only in wood biofilms incubated in secondary wastewater effluent. More total coliform grew in wood biofilms than MP biofilms, and biofilms grown on MP and woodchips were more resistant to disinfection than planktonic bacteria. Therefore, referencing the disinfection literature for fecal indicators in biofilms on other particles could help predict behavior on MP, and treatments that remove particles in general would reduce the potential for fecal indicator bypass of disinfection.

Summary: The study aimed to understand the abundance and diversity of extracellular, intracellular, and total antibiotic resistance genes (ARGs) along a land use gradient and evaluate the impact of bioinformatics pipeline on the assignment of putative hosts for the ARGs observed in different DNA fractions. Results showed no significant differences in the sul1 concentrations between the DNA fractions. The overall microbial community structure was more similar for intracellular and total DNA compared to extracellular DNA. ARGs associated with mobile genetic elements increased in intracellular DNA for the downstream sites. Regarding host assignment, the network analysis of raw reads pipeline identified more ARG hosts compared to the assembly pipeline. Other comparisons were made including ARG assignment to taxa containing waterborne pathogens and practical considerations regarding processing time.

Summary: COVID-19 wastewater-based epidemiology has been conducted in various catchments with different sewer types and sizes. This study compared weekly observations of SARS-CoV-2 genes in municipal wastewater across multiple seasons, considering sewer type and system size. The strongest correlations were found between wastewater N1 concentrations and cumulative clinical cases reported in the 2 weeks prior to wastewater sampling. Sewer type and size did not necessarily explain the strength of the correlations, indicating the influence of other factors.

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.
