Summary: This study investigates the long-term effects of urbanization and industrialization on coastal trace metal contamination. The results show that sediment core Q23 experiences higher trace metal contamination and ecological risks compared to core Q21. The increasing trends in metal concentrations and contamination levels are more obvious since the 2000s, and the urbanization rates in the new area are significantly correlated with historical metal concentrations in Q23.

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: A detailed study of a sediment core from Daya Bay in South China has shown three stages of heavy metal deposition over the past century. Prior to the 1980s, heavy metal concentrations were low with limited influence from human activities. From the 1980s to 2000, metal pollution increased, primarily due to anthropogenic activities such as oil and petrochemical industries and fuel combustion. Atmospheric deposition and mariculture also contributed to the increase in certain heavy metals. Since 2000, heavy metal concentrations have declined and stabilized. However, ongoing anthropogenic input of copper and lead poses a moderate pollution risk. The modified pollution index and modified ecological risk consistently indicate a moderate ecological risk from heavy metals in Daya Bay over the past 70 years.

Summary: Trace metals in sediments from the Chester River were investigated to understand their distributions and potential sources. The concentrations of lead, arsenic, nickel, chromium, and copper exceeded sediment toxicity guidelines in a significant proportion of samples. Enrichment factors for cadmium, silver, lead, arsenic, and zinc were elevated above natural background levels. Nickel, copper, zinc, and cadmium showed significant differences in enrichment factors between different segments of the river. Cadmium and arsenic enrichments were most likely from the application of fertilizers in the watershed, while active marinas were identified as important sources of metal enrichment, especially for copper.

Summary: The concentrations of trace metals (Cu, Pb, Zn, Cr, Cd, As, Hg, Ni, Li, and Co) in sediment cores were studied to determine background levels, assess deposition patterns, and examine contamination in Laizhou Bay, China. Anthropogenic enrichment was observed for Pb, Cd, and Hg, which can be traced back to human activities since 7 thousand years ago. Trace metal concentrations during the 10-7 thousand years ago phase were considered as background levels. Analysis showed that the metals were mainly from natural sources, and contamination was observed for Pb, Cd, and Hg during the 7-0 thousand years ago period.

Summary: Trace metal (loid) contamination in the atmosphere in North China, a global contamination hotspot, has been monitored but there is a gap in understanding its long-term patterns. Historical trends of atmospheric contamination in North China over the past ~500 years were studied using sediment cores from two subalpine lakes. Mercury contamination has continuously increased since the late 1800s, while arsenic, lead, and cadmium contamination lagged behind in one lake compared to the other.

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.
