Summary: Four different types of 0-30 cm soil/sediment samples were collected from aquaculture land, farmland, industrial land, and river bottom sediment in the estuary area of Dagu River to analyze the pollution status and sources of 7 PCB congeners. The results showed low pollution levels in all samples, with the main source of PCBs being shipping activities, along with atmospheric transport and sedimentation sources.

Summary: New organohalides have replaced old ones, leading to their widespread environmental distribution. These compounds are found in both abiotic and biotic matrices, requiring control measures. Remediation techniques such as photodegradation, chemical oxidation, and biodegradation are discussed, with microbial reductive dehalogenation representing a promising method for removal.

Summary: The study found that the recommended e-flows for the Yellow River Estuary in different years and scenarios have significant impacts on both ecosystems and agricultural economy. Prioritizing e-flows in dry years may lead to agricultural economic losses, while in wet years, increasing e-flows can have positive effects on the ecosystem.

Summary: The occurrence of 130 pharmaceutically active compounds (PhACs) in sediments collected from the Odra River estuary was investigated. The compounds had the highest concentration levels near two main wastewater treatment plants and the seaport and shipyard. Pseudoephedrine, clindamycin, nalidixic acid, carbamazepine, fexofenadine, propranolol, and thiabendazole posed the highest environmental risks.

Summary: River deltas, such as the Yellow River Delta in China, are ecologically and socio-economically valuable. The unique yellow-blue demarcation line (YBDL) in the Yellow River Estuary has become a famous attraction and generated significant tourism revenues. This study extracted YBDL from satellite imagery and investigated its spatiotemporal distributions from 2016 to 2022. The results showed that YBDL started to occur frequently after 2018, mainly within 10 km off the estuary, with July having the highest frequency and widespread distribution of YBDL.

Summary: Dynamic variations in the chemical composition and size distribution of dissolved copper along the river-sea interface in the Yellow River Estuary were found. Different fractions of copper were impacted by environmental parameters and dissolved organic carbon differently, with 1-100 kDa copper migrating more violently and tending to be a stable polymer.

Summary: In this study, LC-QTOF-MS and GC-QTOF-MS were used to characterize the occurrence of contaminants of emerging concerns (CECs) in the Yellow River Estuary (YRE) surface water. A total of 295 and 315 chemicals were identified by LC-QTOF-MS and GC-QTOF-MS, respectively. The study identified 81 priority control pollutants in the surface water of YRE based on toxicological priority index (ToxPi).

Summary: The study revealed high concentrations of heavy metals in surface sediment of the Yellow River Estuary, with some metals exceeding their background values. The migration of these metals in the food chain affected the survival and reproduction of wetland birds. Monitoring the contamination and implementing effective management and protection measures for wildlife in the estuary is crucial.

Summary: This study assessed the sources and pollution risk of heavy metals in the Old Yellow River estuary by systematically sampling and analyzing surface sediments. Multiple indicators were used to distinguish the sources and assess the pollution risk. The results showed that some heavy metals were derived from natural sources, while mercury and cadmium were derived from anthropogenic sources.

Summary: This study investigated the presence of Dechlorane series flame retardants (DECs) in surficial sediments from the Pearl River Delta, China. The results showed that DP and Mirex were the main components, with DP concentrations positively correlated with urban activities. Additionally, anti-Cl-11-DP was found ubiquitously in the sediments, indicating it was co-emitted with anti -DP rather than a dechlorination byproduct.

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.

The results showed that the mercury content in the sampled sardines posed no risks to human health. This study is significant as most sardines in Salvador come from Todos os Santos Bay, which has a history of mercury contamination.

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.

Summary: This study examines the movement patterns of plastic marine debris in Indonesian waters, revealing that Indonesia contributes significantly to transboundary marine debris in the Pacific Ocean, Indian Ocean, and the South China Sea. Most of the debris remains in Indonesian waters and moves back and forth due to the influence of monsoon currents.
