Summary: The study found that the presence of different concentrations of copper (Cu) had varying effects on PFOS, with low concentrations causing an increase in PFOS concentration in roots and high concentrations damaging root cell membranes and increasing root permeability. It was also observed that Cu inhibition of carrier proteins could lead to the suppression of acropetal translocation of PFOS, and the presence of a protein-mediated uptake pathway was evidenced by enantiomer fraction (EF) results.

Summary: Biochar is a cost-effective solution for removing per- and polyfluoroalkyl substances (PFAS) from water, but the specific physicochemical properties of biochars that determine their PFAS removal remain unknown. In this study, 15 biochars were produced from five feedstocks at three pyrolysis temperatures to investigate their removal efficiency of perfluorooctane sulfonate (PFOS), a type of PFAS, from water. It was found that biochar pore diameter was the most critical factor for PFOS removal, but other factors such as pore diameter/pore volume ratio, specific surface area, pyrolysis temperature, hydrophobicity, and elemental composition also played roles. Biochars with small pore diameter, low nitrogen content, and high pyrolysis temperature showed enhanced PFOS sorption. These findings contribute to the understanding of using biochars with optimized properties to remove PFAS compounds from water.

Summary: Limited understanding of stress response and tolerance to perfluorooctane sulfonate (PFOS) in plants exists at physiological, biochemical, and molecular levels. Lettuce exposed to PFOS showed accumulation of PFOS in leaves and roots, with different reactive oxygen species (ROS) production and defensive mechanisms observed between the two parts. Multiple defensive strategies in roots contribute to the high tolerance to PFOS.

Summary: This study demonstrates for the first time that PFOS induces ferroptosis in HK-2 cells. Additionally, the involvement of endoplasmic reticulum stress, apoptotic mechanism, and P53-mediated antioxidant mechanism in PFOS-induced cytotoxic damage are explored. These findings provide new insights into the toxicity of PFOS and its impact on kidney damage and mechanisms.

Summary: This study investigated the toxicity of PFOS on the behavioral responses of C. elegans, and for the first time found its transgenerational effects. The results showed that PFOS severely affected locomotion and brood size, but these defects were rectified in the progeny after a few generations. Furthermore, PFOS also affected lifespan and chemotaxis plasticity.

Summary: A UV photoreductive system based on Fe(II)NTA is effective in decomposing PFOS at pH 8.0 under anoxic conditions, with degradation and defluorination efficiencies of around 60% and 29.5%, respectively. Laser flash photolysis and TDDFT calculations reveal a mechanism of UV-induced directional electron transfer from Fe(II)NTA to PFOS in a penta-coordinated metal-ligand complex.

Summary: This study reports decreasing trends in PFAS concentrations in the eggs of 4 seabird species sampled along a nearshore-offshore gradient. The majority of PFSAs, including PFOS, are statistically declining in the eggs of all 4 species, while concentrations of long-chain PFCAs exhibit a trajectory of linear increases and second-order declines.

Summary: The study evaluated the in situ delivery and PFAS sorption capacity of a polymer-stabilized ion exchange resin, showing promising results in adsorbing PFAS in a certain concentration range. Injection of the resin into quartz sand increased retention of PFOA or PFOS significantly, suggesting a potential effective in situ remediation strategy for PFAS-impacted groundwater plumes.

Summary: The study evaluated the geographical distribution and 10-year temporal trends of 17 PFAS in eggs of two gull species from 5 main Spanish colonies. PFOS was the predominant compound in all samples, with varying concentrations and patterns observed among different colonies. The study highlights the importance of continuous long-term monitoring using gull eggs as bioindicators of environmental pollution.

Summary: Catchment-scale plastic pollution assessments provide insights into the sources, sinks, and pathways of plastic pollution. We propose an approach to quantify macroplastic transport and density in the Odaw catchment, Ghana, and find that the urban riverine zone has the highest transport, while the urban tidal zone has the highest riverbank and land macroplastic density.

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: This study used diamondoid hydrocarbon distributions to identify the sources of environmental oil contamination. A suite of 20 diamondoids was found to accumulate in fish adipose tissue. The scatter plots of indices between fish and exposure oils showed a close to ideal 1:1 relationship, which can be used to determine the origin of the oil.

Summary: In this study, the concentration, composition, distribution, and sources of PCBs in surface seawater of the Bohai Bay were analyzed. The results showed that PCBs in the Bohai Bay had high concentrations and were primarily derived from land-based sources such as port activities and river inputs. The PCBs in the Bohai Bay may come from commercial PCBs and their incineration products, municipal landfills, wood and coal combustion, and industrial activities, etc.

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.

Most of the debris remains in Indonesian waters and moves back and forth due to the influence of monsoon currents.
