Summary: With the prohibition of conventional organochlorine pesticides, the use of current-use pesticides such as organic amine pesticides and organophosphate pesticides in agriculture and mariculture activities has become a global concern. A study in the Beibu Gulf, a subtropical agricultural and maricultural zone, found that pesticides were widely present in seawater and sediment, with the most abundant categories being organic amine pesticides and organophosphate pesticides. The spatial distribution of pesticides showed a decrease from coastal areas to the sea, indicating the impact of anthropogenic activities on pesticides pollution.

Summary: This study investigated the binding interactions of three organophosphate pesticides with GpdQ enzyme using computational approaches. The results showed that the pesticides binding could stabilize the enzyme structure in the active conformation, allowing the substrate to be catalyzed into less harmful products. The in silico analysis presented here could be informative for enhancing enzyme stability and activity in the future.

Summary: This study found that children examined soon after a pesticide spray period had lower neurobehavioral performance compared to those examined later, indicating a transient effect of peak pesticide spray seasons on neurobehavior followed by recovery during low pesticide-use periods. It is advised to reduce children's pesticide exposure potential during peak pesticide-use periods.

Summary: The human gut microbiota can be disrupted by environmental contaminants such as pesticides, posing potential health risks. The metabolites produced by gut microbiota play a significant role in maintaining host health, and an imbalance in this system can lead to various diseases. Recent studies have shown that pesticides have harmful effects on the host's gut microbiota. Therefore, further research is needed to understand the impact of pesticides on gut microbiota-mediated metabolic changes, which may provide insights into pesticide-induced toxicity.

Summary: The aim of this study was to determine concentrations of organochlorine pesticides (OCPs) and selected current use pesticides in the placentas of pregnant women from Argentina. The results showed that all pregnant women are highly exposed to complex pesticide mixtures, including banned OCPs and the widely used chlorpyrifos. Intrauterine environment is the first chemical exposure scenario in life, through transplacental transfer.

Summary: The Guayas estuary in Ecuador is the largest estuary system along the western coast of South America, formed by interactions of fresh waters from the Guayas River and marine waters from the Pacific Ocean. The Babahoyo River and to a lesser extent the Daule River are identified as principal sources of fresh water for the entire estuary, with water compositions being more enriched at the end of the dry season. Spatial and temporal variations in the delta O-18-salinity relationships of waters within the estuary regions indicate how river influx, tidal circulation, mixing of waters, and evaporation affect these regions during dry and rainy seasons.

Summary: Streams impacted by urban sewage and landfill had the lowest scores in water quality and phytotoxicity, while those affected by gold mining had the lowest scores in macroinvertebrate community. The absence of macroinvertebrates in gold mining areas should be considered as a warning sign of long-term impacts. The integrated evidence index showed that sites with identified threats had a decline in stream quality of 30%-53% compared to FT sites.

Summary: This study quantified the plastic litter and microplastics in sediments of a beach in a riverine depositional area in the upper Amazon River basin, Ecuador. Plastic density was low but microplastic concentrations were relatively high, with blue fibers being the prevalent type. The findings highlight the need for monitoring and managing plastic waste in freshwater beaches to address this underreported issue.

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: 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.
