Summary: In this study, concentrations of essential and toxic metals in Procambarus clarkii from Lake Trasimeno were quantified. The results showed differences in metal concentrations among tissues, seasons, and gender. Essential metals accumulated in higher concentrations and showed stronger associations, especially in females. Significant differences in concentrations were observed between seasons for essential metals and silver. A seasonal toxicity index indicated that nickel contamination levels in sediments were affected by fluctuating hydrological levels of the lake.

Summary: This study assessed the impact of intensive human activities on organic matter and heavy metal cycles in Shihwa Lake, South Korea. The results showed that the vertical supply of organic matter was a major controlling factor for benthic respiration, and benthic nutrient flux played an important role in primary production. Higher sediment oxygen demand may accelerate the release of certain heavy metals. The benthic fluxes of certain heavy metals were highest near the industrial complex.

Summary: The study found that the average concentrations of six heavy metals in the sediment of the lower Meghna River estuary were ranked in descending order of iron (Fe), zinc (Zn), lead (Pb), chromium (Cr), copper (Cu), and cadmium (Cd). The geo-accumulation, contamination, and pollution load indexes indicated that the estuary was not contaminated by Fe, Zn, Pb, Cr, and Cu. There was a significant correlation between sediment grain size and the association of iron (Fe) and lead (Pb), but no significant correlation was found between other metals and grain size.

Summary: Environmental pollution caused by heavy metals is a significant threat to the environment and human health. Using safer substitutes for toxic heavy metals, like Bi instead of Pb, is a potential solution. However, there is limited research on the effects of Bi on living organisms, especially plants. This study found that Bi has a toxic effect on plant growth, reduces chlorophyll and carotenoid content, impairs nitrogen balance, and affects the photosynthetic machinery.

Summary: Lead and mercury emissions and deposition have long histories extending into preindustrial times, but the timing, magnitude, and persistence of preindustrial emissions remain unclear. This study uses a well-dated sediment core from Lake Antoine, Grenada to assess the past 3000 years of tropical lead and mercury deposition. The results show that preindustrial increases in lead and mercury concentrations can be explained by variations in mineral and organic matter inputs from the watershed, reflecting climate-driven changes in the lake level. There is no evidence that preindustrial use of lead and mercury raised deposition rates in this remote ecosystem. Industrial-era accumulation rates in Lake Antoine have been accelerated by land use and land cover change within the crater rim, but global industrial pollution is still evident. After correcting for watershed inputs, recent atmospheric deposition rates of lead and mercury are in close agreement with monitoring data, challenging previous assessments that suggested preindustrial use of mercury raised atmospheric deposition rates globally.

Summary: This study examines the contamination, accumulation, and ecological risk of five trace metals in sediments of an urbanized beach in Morocco. The results show that, overall, the sediments were within the acceptable limits, indicating low contamination and low ecological risk. However, there was an increase in Cd levels in 2019 due to anthropogenic activities, leading to moderate pollution and moderate ecological risk. It is recommended to reduce avoidable human activities to mitigate metal pollution in the study area.

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.
