Summary: This study explored the use of hydroxyapatite-gravel media in constructed wetlands (HA CWs) to effectively adsorb fluoride (F) and heavy metals (HMs) and enhance nitrate (NO3--N) reduction. The results showed that HA CWs had significantly higher removal efficiency for F, Cr, As, and NO3--N compared to conventional gravel substrate (CK CWs). HA substrate in CWs promoted the growth of wetland plants and enriched key functional genes related to nitrogen biotransformation, energy metabolism, and metal ion reduction.

Summary: The pH of tree bark is influenced by various factors, including epiphytic bryophytes and the inclination of branches. This study found that the effect of bryophytes on the pH of the bark depends on the inclination of branches, with higher inclination leading to a decrease in pH reaction and lower inclination leading to an increase in pH.

Summary: In this study, we examine the sensitivity of global mining stocks to precious and industrial metals by introducing a metal factor into the CAPM and Fama-French models. Our findings suggest that metals play a fundamental role in explaining the returns of mining stocks and have a stronger influence than Fama-French factors. Additionally, we find that metals are more significant for precious metals stocks than industrial metals stocks, especially for firms based in developed markets. On the other hand, the market factor is more relevant for industrial metals stocks. Our results indicate that investors should differentiate mining stocks and consider the distinction between precious and industrial metals.

Summary: The study found that the combined effects of ocean acidification and heavy metals on marine organisms are predominantly additive, with a significant proportion of synergistic interactions and a small amount of antagonistic interactions. The overall adverse effects of heavy metals on marine organisms are mitigated by ocean acidification, leading to a neutral impact of heavy metals in combination with ocean acidification. Different taxonomic groups show varying responses to heavy metals and ocean acidification, with microalgae being the most sensitive when exposed to both stressors.

Particularly for small villages and isolated areas, CWs provide an energy- and land-efficient alternative to traditional treatment systems. This study aims to offer sustainable options for the effectiveness and use of CWs by evaluating their application and recent developments in their design and operation. The study also emphasizes the importance of future research in improving the sustainability and stability of CWs.

Summary: Area-selective etching (ASE) of polymers is a novel and simple self-aligned patterning technique with potential application in semiconductor device fabrication. The polymer film is selectively decomposed on top of catalytically active materials while staying intact on catalytically inactive materials, eliminating edge placement errors and defects. This study investigates the ASE of poly(methyl methacrylate) (PMMA) using various catalytic materials in different atmospheres. The feasibility of the entire patterning process is demonstrated on a 100 nanometer scale.

Summary: This study evaluated changes in lake and peat porewater chemistry in the Sudbury area and found that DOC concentrations increased over time, primarily affected by increasing pH and decreasing lake SO4 concentration. Strong relationships between DOC and pH (positive) and SO4 (negative) were observed in lakes, indicating that recovery from acidic deposition is the main factor contributing to the increase in DOC in Sudbury lakes.

Summary: The Turkey Lakes Watershed (TLW) study is a federal interdepartmental study established in 1979 to investigate the effects of acid rain on terrestrial and aquatic ecosystems. This multidisciplinary study conducted at the 10.5 km(2) watershed in the Eastern Temperate Mixed Forest on the Canadian Shield has evolved from focusing on acidification to investigating the effects of climate change, forest harvesting, and other forest ecosystem perturbations. The comprehensive data collected have contributed to over 400 published research papers and influenced pollutant emission and resource management policies at provincial, national, and international levels.

Summary: Defoliating insects disrupt boreal catchments by redistributing carbon and nitrogen from forests to lakes, altering biogeochemical cycles significantly. DOC reductions and DIN increases in lake waters due to insect outbreaks exceed between-year trends, indicating the importance of these outbreaks in driving biogeochemical cycles in forest catchments.

Summary: Forest harvesting has impacts on dissolved organic matter (DOM), food web structure, and aqueous mercury inputs in small streams. This study found that while measures of DOM quality and autochthony in caddisflies varied among sites, there were no upstream-to-downstream differences between partially harvested and reference catchments. However, mercury levels in stream water and caddisflies were significantly higher in upstream sites of harvested catchments compared to reference catchments, indicating the impacts of forestry activities on mercury did not manifest at larger spatial scales.

Summary: Previous studies have shown that the impacts of harvest on stream chemistry in deciduous forests with seasonal snow cover vary and may take different recovery times. In this study, we investigated the interactive effects of forest harvesting with regional and global environmental changes on stream solute concentrations and other parameters. The results showed that the impacts of harvest on stream chemistry were greatest in clearcut areas, moderate in selection cut areas, and least in shelterwood cut areas. The impacts typically lasted for one to six years, although some solutes were impacted for the entire 21 year post-harvest period. Different solutes showed different response patterns, which were consistent with expected changes in nutrient demand, sources, and transport due to harvesting. Comparing harvest impacts to long-term climate change and acidification recovery revealed antagonistic or synergistic effects depending on the solute. These findings highlight the importance of long-term monitoring to accurately understand the consequences of forest harvesting practices in the face of environmental change.

Summary: This Perspective presents an integrative framework to improve estimates of land-atmosphere carbon exchange by considering the accumulation of carbon in the landscape and its export through rivers. The framework uses the watershed as the fundamental spatial unit and integrates all terrestrial and aquatic ecosystems. The application of this framework can bridge the gap between land and atmosphere-based approaches and enhance communication and collaboration among research communities.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
