Summary: Perfluorinated compounds (PFCs) are a class of new persistent organic pollutants widely found in the environment. This study examined the effects of two typical PFCs, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), on the composition and diversity of soil microorganisms and the availability of soil macronutrients in urban forest ecosystems. The results showed that PFOA and PFOS application significantly increased soil nitrate and ammonium content, while total phosphorus content remained unchanged. Total potassium content decreased in PFOA treatments but increased in PFOS and PFOA-PFOS combined treatments. The dominant bacterial phylum shifted from Chloroflexi to Acidobacteria with increasing PFCs concentrations. Fungal community composition did not change significantly in response to PFCs treatments. Soil bacterial richness decreased but diversity increased, while fungal richness and diversity generally decreased with increasing PFCs concentrations. Soil fungal community was found to be more sensitive to PFCs pollutants than bacterial communities. Structural equation modeling revealed that PFCs exposure indirectly affected the diversity and richness of soil bacteria and fungi by directly impacting nitrate and ammonium content. The concentration of PFCs pollutants played a primary role in determining the composition, richness, and diversity of forest soil microbial communities.

Summary: This research focused on the relationship between soil porewater concentrations and soil concentrations of PFAS, based on a comprehensive model. The model was validated using measured parameters and literature data, showing accurate predictions of concentration ratios. Numerical simulations demonstrated the importance of air-water interfacial adsorption for the distribution of longer-chain PFAS. It was found that PFAS soil porewater concentrations can vary from ng/L to mg/L depending on soil concentrations and site conditions.

Summary: The concentrations and profiles of 17 PFAS were analyzed in freshwater fish samples from West Lake and Yen So Lake in Vietnam. The study found that PFAS concentrations were higher in fish blood samples, and liver samples had significantly higher levels compared to muscle samples. The majority of PFAS were found in muscle and blood, with individual compounds contributing to the overall burden to varying degrees. The most common PFAS substances were PFOS and PFA with chain lengths from C10 to C14. There were no significant differences in PFAS concentrations between different fish species, although common carp showed specific PFAS profiles compared to other species.

Summary: In this study, the effects of environmentally-relevant levels of PFAS on caged canaries were analyzed using physiological, immunological, and transcriptomic analyses. Although no effects were observed on physiological and immunological parameters, the transcriptome of the pectoral fatty tissue showed changes compatible with the known effects of PFAS as obesogens in other vertebrates. These results indicate the potential hazard of PFAS on the fat metabolism and the immunological system of birds and highlight the ability of transcriptomic analyses to detect early physiological responses to toxicants. Tight control of the exposure of natural populations of birds to these substances is necessary due to the essential functions affected.

Summary: Many first trimester sporadic miscarriages are unexplained, and this study aimed to investigate the association between levels of Perfluoroalkyl substances (PFASs) in early pregnancy with unexplained first trimester miscarriage. The results showed a positive correlation between PFOA exposure and sporadic first trimester miscarriage, while other PFASs showed no significant association with miscarriage. This suggests a potential shared but unknown mechanism between PFOA exposure and miscarriage.

Summary: This study investigated the short- and long-term effects of two commonly detected compounds, perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA), on the laboratory-reared mayfly Neocloeon triangulifer in water only exposures. The study found that mayflies were highly sensitive to PFOS and PFOA, with PFOS being more toxic than PFOA. The research highlights the risks of PFOS to freshwater insects and suggests the need for further investigation into the toxicity of different compounds on these organisms.

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.
