Summary: In this study, the concentrations of 10 heavy metals were measured in superficial sediments from the Bach Dang Estuary in Vietnam. An integrated approach was used to identify the possible sources of these heavy metals, including correlation analysis, principal components analysis, and positive matrix factorization. The results showed that the heavy metals originated from natural geogenic, mixed anthropogenic, marine transportation, and anti-fouling paint related sources, contributing different proportions to the total metal concentrations. From an environmental perspective, these findings provide a scientific basis for preventing and controlling sediment metal pollution, suggesting the use of more environmentally friendly antifouling paints to minimize metal accumulation in sediments.

Summary: This study investigated the distribution, controlling factors, environmental quality, and primary sources of heavy metal elements in surface sediments from the Malacca Strait. Results showed that heavy metal elements were abundantly distributed near the coast of Malaysia, gradually decreasing toward the sea, and increasing in waters close to the Perak estuary. Natural weathering was the main source of heavy metals, while some were affected by human activities. The assessment of environmental quality revealed pollution-free levels for certain heavy metal elements, moderate pollution for others, and high ecological risk for Hg and high-risk index for As elements.

Summary: This study investigated the content of six heavy metals and particle sizes in the sediments of the southern North Yellow Sea. The results showed that copper and chromium were mainly enriched in coastal areas with high mud content, while zinc, cadmium, lead, and mercury were enriched in areas with denser populations, estuaries, and shipyards. The contamination assessment revealed that copper and chromium contamination was low and mainly derived from natural processes. Zinc and cadmium pollution in the nearshore area was moderate and had both natural and human activity sources. However, most areas had lead and mercury contamination due to waterborne traffic and industrial activities.

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.
