As per the findings, the aqueous MB dye underwent oxidation primarily due to the presence of the superoxide (<span>({O}_{2}^{bullet -})</span>) radical. The nanocomposite photocatalysts exhibited photodegradation efficiency exceeding 91.47% and displayed remarkable stability, as evidenced by the absence of any noticeable decline in activity indicated by the repeatability test (five cycles).

MPs abundance varied from 17 to 38 particles/fish sample with a mean of 10 items/fish sample. MPs show variations in shape, size, and color. The occurrence of 189 MPs from the visually identified 210 microplastic-like particles were confirmed by µ-Fourier Transformed Infrared Spectroscope (µ-FTIR). In addition, 12 heavy metals, including arsenic (As), lead (Pb), cadmium (Cd), and iron (Fe), were quantified in different body parts (head, flesh, and bones).

Significant differences in MPs and metal concentrations were observed based on fish size and body part. PCA analysis revealed distinct patterns of metal accumulation across different body parts and fish sizes, with larger fish showing higher levels of Pb and Cu, indicating prolonged exposure. Hierarchical clustering further highlighted similarities in metal distribution, grouping metals such as Pb and Cd due to common sources or pathways of accumulation. The results emphasize the potential health risks associated with consuming larger Hilsa fish due to the occurrence of elevated levels of heavy metal and MPs.

The concentration of PFOS in foam (median 375,000 ng/L) was 18,750 times greater than in water (20 ng/L). Metals in river foam were more abundant than in river water. The median copper in river water was 3 µg/L and nearly 1000 times greater in river foam (median 2900 µg/L). Several metal toxicants (including mercury, cadmium, selenium and lead) were only detected in river foam where they were orders of magnitude higher than ecosystem protection levels. We speculate that aeration of river flow through rapids and waterfalls contributed air bubbles that produced surface foam in a similar process to <i>foam fractionation</i>. Although foam containing PFOS has previously been documented within a freshwater lake, the hyperaccumulation of metals within PFOS-enriched foam on the surface of a river appears to be a novel phenomenon and warrants further investigation to determine the bioavailability of the hyperaccumulated chemicals.

This study examines the distribution and influencing mechanism of trade-attributed GHG inequality across 49 economies from 1995 to 2022. We integrate a GVC decomposition model with an optimized regional environmental inequality index to assess the trade-attributed GHG inequity. The gravity model is employed to explore the relationship between this inequality and different GVC trade types. Through a structural decomposition analysis, we further unveil the drivers of GHG emissions per value added in crucial GVC trade types to determine effective pathways for alleviating the inequality. Our analysis reveals the following findings: (1) Trade-related GHG emissions and value added are significantly unequally distributed among economies, with this imbalance being more severe between GVCs. (2) Trade-attributed GHG inequalities demonstrate widespread globally and exhibit a worsening trend, with particularly pronounced disparities emerging in trade between developing economies, notably China, India, and Russia. (3) Exports and imports through complex GVCs are the most crucial GVC trade types for exacerbating the inequality. Imports through traditional trade represent another crucial GVC trade type. (4) Reducing GHG intensity plays a vital role in alleviating the inequality. Efforts should focus on targeting specific drivers in crucial GVC trade types to reduce their GHG emissions per value added. This study contributes to the growing body of literature on trade-attributed GHG inequality and provides valuable insights for policymakers working towards more equitable and sustainable global trade practices within the context of GVCs.</div></div>","PeriodicalId":328,"journal":{"name":"Global Environmental Change","volume":"92 ","pages":"Article 102997"},"PeriodicalIF":8.6,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143823647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although PFAS contamination has been extensively studied in high-income countries, there is limited data on its occurrence and impact in low and middle-income countries, particularly in Africa. This study addresses the lack of comprehensive data on PFAS in wastewater treatment plants (WWTP), surface water, and sediments in Pretoria (South Africa), to inform pollution control strategies and health risk assessments. The Apies River in Pretoria, which receives treated effluent from nearby WWTPs, was selected for investigation due to its importance to local communities and potential exposure to PFAS. Samples were collected during the dry season weekly on days 1, 7, 14, and 21, to investigate temporal variations in PFAS concentrations in treated effluent, sediment, and surface water, and analysed for legacy and emerging PFAS. Sampling during the dry season provides an opportunity to detect and quantify PFAS more effectively as they are less likely to be diluted by rainfall. PFAS were recovered from the samples using solid-phase extraction followed by liquid chromatography-tandem mass spectrometry. The results showed that the ΣPFAS concentrations were consistently higher in treated effluent samples over 21 days. Long-chain PFAS concentrations were significantly different (p &lt; 0.05) between upstream and downstream locations. Perfluorocarboxylic acids were consistently found at higher concentrations in treated effluent, surface water, and sediment samples, with surface water (downstream) showing the highest concentration (62.98%).
