Summary: This paper investigates the effect of salinity and oil exploitation on the germination of soil seed banks of three dominant vegetation communities in the newborn coastal wetland in the Yellow River Delta of China. The results show that soil salinity has a significant inhibitory effect on the seedling numbers, density, and species diversity of the soil seed banks, while the effect of diesel is indistinctive under the designed concentrations. Soil salinity is considered an important factor for wetland vegetation restoration, with species-specific differences in its effect.

Summary: The study found significant differences in phosphorus fractions between soils of wetlands with different climax vegetation covers, with lower Pi content in PA soils and higher Po content in SH soils. Additionally, AP distribution varied among the wetlands, with SH soils having the highest proportion at the surface layer. These findings highlight the complexity of phosphorus dynamics in estuarine wetland soils and emphasize the need for further research on the biological mechanisms of climax vegetation covers on P absorption and utilization by plants.

Summary: The aim of this study was to analyze the content of heavy metals in the shells of freshwater gastropods Viviparus sp., evaluate the correlation of trace element accumulation in biological objects, bottom sediments, and water, and assess the pollution level of minor rivers in St. Petersburg. The data obtained showed contamination of the Neva River Delta with metals such as Al, Mn, Fe, Cu, and Pb, and significant accumulative capacity of bottom sediments with Zn, Pb, Ni, Cu, Mn, and Fe. The gastropods exhibited a high bioaccumulation ability, depending on the properties of metals, river hydrology, and sediment characteristics. Sr, Fe, Cr, and Mn were found to have the best ability to bioaccumulate in gastropod shells.

Summary: The discharge of pollutants into the Yellow River has been controlled since 2013, resulting in an improvement in the overall water quality. However, the contamination status and sources of heavy metals in the river remain unclear. Our study found that heavy metal contents in sediments remained stable over time, but there was a significant reduction in surface water. No heavy metal contamination was observed in surface water, and the distribution of heavy metals along the river did not show significant spatial differences. Sediments were assessed as having a low to moderate contamination degree. The upstream and midstream had higher concentrations of heavy metals compared to the downstream. Anthropogenic activities and soil erosion from the Loess Plateau were identified as important sources of heavy metals in the Yellow River sediments.

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: 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.
