Summary: This study reconstructed the temporal trends of both legacy and novel BFRs in sediment cores along the Rhone River. It was found that while legacy BFRs peaked in concentration from the mid-1970s to the mid-2000s and stabilized by the mid-2010s, novel BFRs had concentrations two to four orders of magnitude lower and showed no decrease in recent years. Understanding the sources, contamination load, repartition in the environment, and toxicity of novel BFRs is necessary before their concentrations reach hazardous levels.

Summary: Few studies have been conducted on the spatial and temporal trends of polychlorinated naphthalenes (PCNs) in coastal environments. This study investigated the presence of 18 PCN congeners in sediment samples from industrialized bays in Korea, and found measurable PCN levels in all samples. The highest levels were observed in sediment from areas surrounded by industrial complexes and commercial harbors. Congener patterns and diagnostic ratios suggested that PCN contamination originated from combustion processes and the use of PCB technical mixtures. The PCN concentrations in dated sediment showed an increase from the 1980s to the mid-2000s, followed by a decrease until 2015. Although the levels of PCNs did not exceed international sediment quality guidelines, cumulative risks for benthic organisms may still exist due to the presence of other contaminants.

Summary: PCB sulfates bind reversibly with high affinity to human serum proteins, are taken up by cells and tissues, and may be hydrolyzed to more toxic OH-PCBs. Human hepatic microsomal sulfatase can catalyze the hydrolysis of PCB sulfates to OH-PCBs, potentially contributing to the retention and increased exposure time of OH-PCBs.

Summary: The historical trends and inventory of organophosphate esters (OPEs) in sediment cores from the tidal flat of the Liao River estuary in northeastern China were investigated. The concentration of n-ary sumation 13OPEs in the sediment cores has shown a continuous increase since records began, with a peak in the 1960s, a decline in the 1980s, and a subsequent rise in the 2000s. Tributyl-n-phosphate was found in each layer of the sediment cores, accounting for a significant portion of the total OPEs. The study provides important insights into the contamination trends of OPEs in Chinese sediments and its environmental risks.

Summary: The study quantified selected PCB congeners in Chabahr bay and surrounding areas in Iran, with concentrations varying from below detection limit to 485 ng kg-1 dry weight of sediment. The dominance of PCB 28 and 52 suggests maritime transportation and atmospheric deposition as important sources, with commercial products like ClophenA50 also potentially contributing. Overall, the impact of detected PCBs on aquatic organisms was deemed negligible based on guidelines.

Summary: A sharp decline in sediment load at the seaward most Datong station of the Yangtze River since 1956 is attributed to changes in sediment contributions from tributaries and mainstream due to impoundments of Three Gorges Dam and cascade dams. The new sediment budget method developed in this study reveals a significant shift in sediment suppliers from upper to middle-lower reaches after 2003, resulting in a drastic reduction in sediment loads.

Summary: Improved analytical methods have allowed the quantification of numerous pesticide transformation products in aquatic environments, yet there is limited understanding of their occurrence and potential toxicity. Through analyzing samples from 442 small streams in urban basins across the United States, it was found that transformation products were detected nearly as frequently as parent pesticides. Detection of these transformation products during baseflow conditions suggests chronic exposure of aquatic organisms and potential groundwater sources.

Summary: This study demonstrates the advantages and limitations of using passive samplers for monitoring polar contaminants in surface waters. The results show that POCIS has a higher quantification frequency for most contaminants compared to spot samples, and it lowers the limits of quantification. POCIS is able to capture short-duration and high-intensity contamination events, and it provides more reliable annual monitoring and assessment of environmental quality compared to spot sampling.

Summary: This study examined the effect of karst on antibiotic-resistant bacteria, specifically extended-spectrum beta-lactamases-producing Escherichia coli (ESBL-Ec), in a rural karst hydrosystem providing drinking water. The concentrations of ESBL-Ec were found to be spatially and temporally heterogeneous, with no filtration effect observed in the karst. The results suggest that karst poses a risk for the transmission of antibiotic-resistant bacteria.

Summary: Understanding the accumulation and transport of microplastic particles (MPs) in rivers is challenging, especially in rivers with variable particle sizes and complex interactions with dams and plastic production centers. This research focused on the Ain River in France, where plastic factories and dams are present. By using Geographical Information Systems (GIS) to locate plastic factories and characterize land use, as well as analyzing sediment samples and measuring hydro-sedimentary settings, the study found high concentrations of MPs near plastic production centers. The results provide important insights for managing MPs in coarse-bed rivers.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
