Summary: This study investigated the levels of trace metal(loid)s in various vegetables in Malatya province, Turkey, and assessed the non-carcinogenic health risks associated with consuming these crops. Overall, the levels of most trace metal(loid)s were below the maximum permissible concentrations. However, the consumption of tomatoes was found to pose a non-carcinogenic risk due to the combined intake of certain trace metal(loid)s.

Summary: This study assesses the impact of two types of dissolved organic matter (DOM) on the bioavailability of copper (Cu) to phytoplankton. Results show that at higher Cu concentrations (100 nM), DOM decreases Cu internalisation in phytoplankton, consistent with ASV measurements. However, at lower Cu concentrations (20 nM), organic complexes appear to be partially bioavailable, challenging the general applicability of the biotic ligand model (BLM).

Summary: This article empirically analyzes the direct and indirect effects of human capital on energy consumption in Algeria and tests the presence of the energy-environmental Kuznets curve hypothesis. The results show that human capital indirectly affects energy demand through income and physical capital stock channels, but the direct effect is stronger. The study also finds a monotonic increasing relationship between energy use and real GDP per capita, indicating no evidence of the E-EKC hypothesis. Additionally, physical capital stock per capita, urban population ratio, and real GDP per capita are positively linked to energy use per capita. Thus, investing in education and improving the quality of human capital is a good strategy for Algeria to reduce energy consumption and protect the environment without negatively impacting economic growth.

Summary: This study examines the determinants of profit rate and factors associated with UK recessions using quarterly data from 1985Q1 to 2019Q4. The findings suggest an inverse relationship between the wage share of income and profit rate, with capacity utilization, capacity-to-capital ratio, and monetary expression of labor time positively impacting profit rate. The probability of a recession decreases with higher profitability, supporting the wage-led hypothesis. The impact of interest rates on UK recessions is found to be insignificant.

Summary: One of the best approaches for improving the assessment of metal toxicity in aquatic organisms is to study their organotropism through kinetic experiments of metal bioaccumulation. This study compared the organ-specific metal accumulation of non-essential (Cd) and essential (Zn) metals in Gammarus fossarum. The results showed different distribution patterns of Cd and Zn concentrations, slower elimination of Cd, and a major role of intestines in the uptake of waterborne Cd and Zn.

Summary: The baseline study of natural and anthropogenic radionuclides in Sabaki River estuary showed no exponential decrease of excess Pb-210 down the cores, making dating and determination of heavy metal pollution history impossible. Cs-137 cannot be used as a time marker due to its low fallout rates in East Africa. The use of Be-7 as a tracer confirmed a flood in 2018. Heavy metal concentration showed nonsystematic trends with depth, with only Pb concentration higher than background levels. The potential dose rates to biota from sediment radioactivity concentrations are unlikely to pose appreciable ecological risks, as confirmed by the ERICA tool.

Summary: This paper presents a new explanation for the slow proliferation of straw return in China based on a study of 1166 maize-planting farmers in Liaoning province. The results show that the low adoption rate of straw return can be partly attributed to farmers choosing to undertake off-farm work. The study also finds that intelligent and risk-tolerant farmers have additional negative impacts on the likelihood of straw return adoption.

Summary: We analyze the predictive power of climate risks, represented by changes in global temperature anomaly and its volatility, on periods of zero or negative growth rates in eight industrialized countries. Using a Probit model and controlling for inflation and interest rates, we examine the longest available historical datasets for these countries from 1311 to 2020. The results provide strong evidence that changes in global temperature anomaly and/or its stochastic volatility can predict economic slowdown or stagnation in all eight economies across different time horizons.

Summary: Several international organisations have recommended the use of bioindicators to improve the evaluation of ecological risk in marine ecosystems. In this study, wild mussels were collected from thirty sampling points along the Asturias coastline and analyzed to identify the relationship between metal concentrations in mussel tissues and the geological and environmental conditions of the coastal area. The study revealed concentration trends for different metals and correlations between them. The mussels also showed natural defense against certain metals. Cluster analysis of the samples grouped them based on the sources of the metal concentrations. Both anthropic and natural sources have led to an increase in metal loads in mussels, sometimes exceeding international environmental criteria.

Summary: OSDA-free aluminosilicate chabazite (CHA) catalysts incorporated with metals (MeCHA) by in-situ method were successfully synthesized using a green template-free method in a fluoride medium. The detailed characterizations of the catalysts showed that MeCHA preserved the inherent properties of the parent chabazite zeolite, with acidity strength dependent on the type of metal incorporated. MeCHA zeolites incorporated with Ni, B, Mg, and Fe exhibited good activity and better selectivity in the conversion of methanol to olefins compared to parent CHA.

Summary: This study aimed to investigate the relationship between sediment concentrations of eight total metals and five simultaneously extracted metals with benthic metrics in an agricultural water body. The total arsenic, lead, and cadmium showed significant relationships with benthic metrics, while copper, nickel, zinc, chromium, and mercury did not. Simultaneously extracted metals also had no significant relationships with benthic metrics. Stress tolerant and stress sensitive benthic metrics were found to be effective in detecting adverse effects from metals. The comparison between significant benthic metric relationships and threshold effect level exceedances for metals yielded mixed results.

Summary: In this study, paleoredox conditions in the Western Equatorial Atlantic (WEA) during the glacial-interglacial cycle were reconstructed using high-resolution REEs data and anomalies. The results indicate that the Parnaiba River is the main source of REEs in the western South Atlantic, and changes in the negative Ce-anomaly suggest a reduction in deep ocean oxygenation during the interglacial period. Additionally, the origin of positive Eu anomalies in the core is attributed to preferential retention by feldspars.

Summary: Seabird feathers are important matrices for analyzing environmental contaminants. In this study on brown boobies, the concentration of total mercury (THg) was measured in different types of feathers, revealing higher levels in ventral and wing feathers compared to dorsal and tail feathers. Juvenile birds had lower concentrations of THg in all feather types compared to adults. Ventral feathers are suggested as the most suitable biomonitor for THg contamination in brown boobies, but further studies are needed for other tropical seabird species.

Summary: This paper introduces the ECCANDE project, a Special Protection Scheme (SPS) based on the structure of a Wide-Area Monitoring, Protection, and Control System (WAMPACS). The project enables the interconnection between the Argentinean and Paraguayan bulk power transmission systems, protecting the Itaipu and Yacyreta power plants. The development and implementation of this WAMPACS-based SPS took over a decade, involving modeling, design, manufacturing, simulations, and field tests. Results demonstrate that the ECCANDE SPS successfully enables interconnection and protects against synchronism loss.

Summary: Firearms and ammunition identification plays a crucial role in solving crimes and confirming offenders. Qualitative analysis and standards can be used to investigate cases when suspect weapons and ammunition are found at crime scenes. In cases where only ammunition fragments are discovered, alternative methods such as analyzing the elemental composition of lead alloy and verifying lead isotopic ratios are necessary. This study reviews basic ballistics concepts, conventional ballistic confrontation techniques, chemical analysis of ballistic fragments, and the use of lead isotopic analysis in ballistic identification.

Summary: Sediments collected from the Potiguar Basin in northeastern Brazil were found to be rich in organic matter and metals, with metal concentrations increasing with depth. The distribution of iron (Fe), chromium (Cr) and copper (Cu) suggests some changes along the sediment transport, with Fe and Cr being less affected by accumulation in deeper sediments.

Summary: The study focused on heavy metal pollution in the green vegetation of a suburban industrial area in Tuokexun County, Xinjiang, China. The results showed that the overall level of heavy metal pollution in the soil was minor, with mercury (Hg) being the most severe contamination, likely caused by human activities. The composition of heavy metal elements in trees was more stable compared to grass and shrubs, with varying concentrations across different vegetation. Shrubbery was found to be the most effective in heavy metal restoration, and there were disparities in heavy metal enrichment among different vegetation types.

Summary: Plastic pollution has significant environmental impacts, largely due to chemical additives. However, the behavior of plastic additives in marine environments is not well understood. A marine deployment experiment was conducted to investigate the effects of weathering on the extractables profile of four types of plastics in New Zealand over a period of nine months. The concentration of additives in polyethylene and oxo-degradable polyethylene was strongly influenced by artificial weathering, while polyamide 6 and polyethylene terephthalate showed minimal change. These findings emphasize the importance of considering leaching and weathering effects on plastic composition when assessing the potential impact and risk of plastic pollution in receiving environments.

Summary: Few studies have examined the impact of urbanization and meteorological events on microplastics discharged into the sea through rivers. Surface water samples were collected from two Lebanese rivers, with differing degrees of urbanization, during dry and wet periods. The results showed that the most industrialized river had a significantly higher abundance of microplastics compared to the less-industrialized river. There was also a correlation between particle contamination and the season at each site, with microplastic concentrations highest on the first day of the wet season. These findings highlight the importance of considering meteorological events in accurately assessing plastic pollution influx into coastal waters.

Summary: This study investigated the variability in phytoplankton functional structure using a trait-based approach and explored the relationship between species traits and environmental factors, as well as their impact on ecosystem functioning. The results revealed that morphological traits, temperature, and ammonia played a decisive role in the seasonal succession of phytoplankton species. It was found that certain traits favored higher biomass production but might hinder energy transfer efficiency. The strong correlation between environmental variables and phytoplankton functional structure supports the practical implementation of a trait-based approach in studying phytoplankton community dynamics under different environmental conditions.
