Summary: Glyphosate, an active ingredient in agricultural herbicides, can inhibit the biosynthesis of aromatic amino acids in plants, and its effect on the gut microbiota may have neurological outcomes. In a study on mice, it was found that there were little changes in neurobehavior under glyphosate exposure, but significant differences in fecal metabolomic profiles. Aromatic amino acids were reduced in the feces, indicating dysregulation in tryptophan metabolism. However, there was little evidence to support the impairment of the gut-brain axis.

Summary: A sensitive method for the analysis of glyphosate, AMPA, and glufosinate in water was developed using liquid chromatography/tandem mass spectrometry. The results showed that glyphosate and AMPA were frequently detected in groundwater and surface water, but their concentrations were below the maximum levels allowed by Brazilian legislation and below the most critical toxicological endpoints for aquatic organisms. However, continuous monitoring is necessary due to the widespread use of glyphosate worldwide.

Summary: The study found that wetland biofilms can remove contaminants such as glyphosate through bioconcentration and metabolism. The concentrations of glyphosate in biofilms were several orders of magnitude higher than in the surrounding water, and bioconcentration factors and metabolic patterns indicated that biofilms have the ability to degrade and absorb glyphosate.

Summary: The persistence of glyphosate in forest understory plant tissues in northern British Columbia can last up to 12 years, with root tissues generally retaining residues longer than shoot tissues. Samples from the colder, more northern biogeoclimatic zone retain significantly higher levels of glyphosate for longer compared to samples from the warmer biogeoclimatic zone. This study utilized advanced analytical techniques to elucidate the actual length of time of glyphosate persistence, rather than relying on estimations based on half-life curves.

Summary: This article investigates the generation and distribution of halogenated natural products (HNPs), specifically halomethoxybenzenes (HMBs), in the ocean and on land. The study finds that HMBs are present in air, precipitation, rivers, forest fungi, and litter. HMBs volatilize and circulate through the atmosphere, precipitation, and rivers, and their production and biogeochemical cycles are influenced by climate change. The study suggests that BAs and DAME are potential indicators for partitioning and exchange processes.

Summary: The use of synthetic molecules in the environment is increasing, causing negative effects on human health and ecosystem services. Understanding their behavior and associated risks is important to limit their use. Glyphosate-based herbicides are widely used in farmlands and woodlands to combat weed problems, but they have been linked to toxicological concerns and health issues. This review aims to compile data on their use, potential risks, and recommended maximum residual limits for crops.

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.
