Summary: This study aimed to evaluate the spatial and seasonal distribution of microplastics in the surface waters of thirteen rivers discharging to the southern Caspian Sea. Microplastics were found to be unevenly distributed in all stations. The average concentrations of microplastics during snowmelt and dry seasons were 1.406 ± 0.1380 microplastics/m(3) and 0.4070 ± 0.01500 microplastics/m(3), respectively. White/transparent polyethylene (PE) particles with the shape of fragment/film and the length (L) of ≤ 1 mm were the most common microplastics. Factors such as sewage and household wastes, landfills, and recreational-tourism, fishing, and agricultural activities contribute to microplastic contamination in downstream stations. The study provides baseline information on microplastics in rivers discharging to the southern Caspian Sea.

Summary: This article addresses the urgent problem of the vast amount of plastic in the ocean and the need to connect research on the impact of plastics on marine life with waste management practices. The proposed framework identifies policy actions to reduce consumption of harmful plastics by using a compound risk score. A case study at a Canadian university is used to illustrate the application of the framework, identifying high-risk plastic items and suggesting policy avenues to improve waste management efficiency. This flexible tool supports local transitions towards reducing marine footprint.

Summary: Plastic waste in the oceans is a growing problem for marine life. This study assessed the presence of microplastics (MPs) in the digestive tracts of Xyrichtys novacula fish from two different areas of Eivissa Island, as well as in the sediment of both areas. The results showed that over 80% of the fish samples had MPs in their gut, with the majority being fibers. Although there were more MPs in the sediment of the non-protected area, there were no significant differences in the number of MPs in the fish from both areas.

Summary: The accumulation of Mismanaged Plastic Waste (MPW) in the environment is a global concern. Estimation of waste generated by countries can be done using globally available data layers and/or empirical surveys. A model study ranked Sri Lanka as the world's fifth worst mismanaged plastic offender based on global metadata, but errors in the source data and parameters used for prediction have been identified. Therefore, Sri Lanka's position in the global ranking needs to be reconsidered, and model predictions should be supported by robust and unbiased surveys based on empirical data.

Summary: The presence and impact of marine litter in submarine canyons is still poorly understood and there are significant gaps in knowledge, particularly regarding the impact of macroplastics in deep-sea environments. There is a lack of standardization in study methodologies, including sampling techniques and classification protocols, which hinders the comparison and analysis of research findings. Furthermore, there is a need for more comprehensive reporting on the interactions between litter and the surrounding environment and biota. Overall, this study highlights the urgent need for standardized methodologies to fully understand and address the impact of marine litter in submarine canyons.

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.
