Summary: This study aimed to quantify the abundance of microplastics in the surface water of the River Thames in the UK. Ten sites in eight areas along the river were sampled from May 2019 to May 2021. Visual analysis and Fourier transform spectroscopy were used to categorize and identify microplastics. The results showed that the abundance of microplastics did not increase along the river.

Summary: This study is potentially the first to investigate the impact of large-scale firework displays on surrounding waterways in terms of microplastic pollution. The study found a significant influx of microplastics, particularly polychloroprene, in the River Thames following the New Year fireworks, which will have detrimental effects on the ecology and aquaculture of the river and neighboring waterways.

Summary: Polychlorinated dibenzo-p-dioxins, dibenzofurans, and biphenyls were measured in the surface sediments of Liangshui River in Beijing, China. The concentrations of these pollutants showed an increasing trend from urban areas to suburban areas. The contamination of dibenzo-p-dioxins and dibenzofurans in the sediments may originate from pentachlorophenol and sodium pentachlorophenate and municipal solid waste incineration, while the major sources of biphenyls were identified as the steel industry, combustion processes, and usage of commercial polychlorinated biphenyl products. Long-term wastewater irrigation poses potential ecological risks to crops and human health as it increases the load of sediment-bound pollutants in agricultural soil. The mean value of total toxic equivalent quantities in the sediment samples exceeded the Canadian interim sediment quality guidelines.

Summary: Polychlorinated biphenyls (PCBs) are a common environmental contaminant. The NYS Department of Health (DOH) issues fish consumption advisories to limit exposure to PCBs. However, there is incomplete awareness and compliance with these advisories. There is a need to consider imperfect adherence to fish consumption guidelines in risk assessment and management strategies.

Summary: The comprehensive study on polychlorinated biphenyls (PCBs) and brominated flame retardants (BFRs) in surface sediments from Hanoi, Vietnam revealed higher levels of pollutants in inner-city river sediments compared to the Red River main stream sediments. Different sediment samples showed varied pollutant profiles, indicating potential different sources and/or seasonal variations. Deca-BDE and DBDPE were identified as the predominant BFRs in the sediments.

Summary: This study investigates the potential impacts of microplastics on the freshwater ecosystem of the River Thames in the UK. By using the INCA microplastics model, the transport and distribution of microplastics along the river system are evaluated, with data from the UK water industry used to drive the model for validation. The results show a gradual increase in microplastic migration and concentration along the river system, with deposition on the riverbed.

Summary: In April 2020, the Covid-19 pandemic increased the demand for single-use plastic, resulting in plastic pollution. This study focuses on the impact of the pandemic and lockdowns on microplastic levels in the river Thames, UK. Water samples were collected from May 2019 to May 2021, and a total of 4480 microplastic pieces, mostly fibers, were counted using light microscopy. The highest microplastic abundance was observed during Lockdown 2 in November 2020, with polyvinyl chloride being the most identified microplastic.

Summary: The study determined the presence of 209 PCB congeners in a sediment core from Lake Biwa in Japan, dating back to 1930 to 2019. Concentrations of total PCBs peaked in the 1960s to 1970s, matching the Japanese PCB production and emission pattern. Specific congeners like CB-7,-11,-47/48/75,-51,-68, and-209 were found to have elevated concentrations with special historical profiles.

Summary: The Wang River is a major tributary of the Chao Phraya River in Thailand, providing sediment to the Chao Phraya Delta. Three major dams along the river impact sediment load differently, with downstream sediment reduction countered by sediment supply from the lower basin. The location of dams and sediment load variation along the river are key factors influencing the impact of dam construction.

Summary: This study investigates the occurrence and distribution of microplastics (MPs) in the upper stretch of River Ganga in India. The study found that MPs were present in both water and sediment samples, with an average of 118.5 particles per 1000 L in water and 131.5 particles/kg dry weight in sediment. Fish samples also contained MPs, with different species having varying amounts, ranging from 12.63 to 53.13 particles per individual. The most common type of MP detected was fibers, and the polymer types varied among water, sediment, and fish samples, with polyethylene being predominant in water, polypropylene dominant in sediment, and polyethylene terephthalate and polystyrene most abundant in fish samples.

Summary: The input of organic matter into stream channels is an important energy source for headwater ecosystems and plays a crucial role in the global carbon cycle. The study focuses on quantifying the mobilization, transport, and storage of organic-rich fine sediment in a Strahler fourth-order stream during intermediate-sized storm events. It is found that the channel bed is consistently a source of suspended load to the channel margins, and the trapping of suspended load by riparian margins limits sediment transport distance and decouples the channel from local terrestrial organic matter exchange.

Summary: This article provides an overview of the interlinkages between plastic waste and persistent organic pollutants (POPs) in the waste management system of India. Plastics and POPs share common traits such as persistence and long-range transportability. Throughout the processes of production, consumption, and disposal, plastics interact with and accumulate POPs, leading to their coexistence in the environment. The recycling of plastic waste also poses as a potential major source of POPs and requires further investigation.

Summary: The study found that EDC contamination in food supplied to markets in Delhi was higher than in Dehradun. Despite lax compliance and control measures in India, dietary exposure to OCPs and PBDEs was comparable to Europe, while exposure to PCBs and dioxins was lower. This suggests that internationally harmonized policies on EDC content in food can lead to better protection of health in both developed and developing countries.

Summary: This study investigated the fate of MPs in agricultural soils amended with sewage sludge and the role of surface water runoff in transferring them to aquatic ecosystems. The study found that MP concentrations remain relatively constant in agricultural soils with low infiltration capacity, and surface water runoff only mobilized a very small percentage of MPs added with sludge. Agricultural soils in semi-arid regions can be considered as long-term accumulators of MPs.

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.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
