Summary: This study revealed that P. australis in the contaminated Sundays Estuary has the ability to absorb organophosphate pesticides (OPPs) and bioaccumulate these compounds, transferring them from roots to leaves. The insignificant correlation between log BSAF and log K-ow and log TFr-l and log K-ow indicates that the uptake of OPPs by P. australis tissues is not dependent on log Kow. The findings suggest that P. australis has the potential to effectively remove OPPs from contaminated water and sediment.

Summary: The recent surge in industrialization has led to the accumulation of different types of pollutants in the environment due to illegal dumping of wastewater. Microalgae bioremediation has emerged as an eco-friendly technique to degrade organic compounds and convert them into non-toxic substances without producing secondary pollutants. Modification techniques such as immobilization and pigment-extraction have enhanced the bioremediation potential of microalgae. However, further research is needed to study the structural and functional responses of microalgae towards pollutant by-products, engineering microalgae to tolerate higher pollutant concentrations, reducing harvesting costs, and monitoring parameters at a large scale.

Summary: This study examines the colonization of microorganisms on polyethylene microplastics and their ability to accumulate organic pollutants, as well as the impact of pollutants on biofilm development. The results show that Pseudomonas aeruginosa can form strong biofilms on microplastics, with fluorescent blue microplastics having the highest protein content. The presence of organic contaminants decreases cell viability on white microplastics, while the overall effect on biofilm formation is negligible. Microbial colonization influences the ability of microplastics to accumulate contaminants, with fluorescent blue microplastics showing the highest sorption capacity.

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.
