The study is necessitated by the fact that much attention has not been given to rehabilitation of degraded riparian flora species in the Upper West Region by scholars and researchers. The current study aims at filling the knowledge gaps on restoration measures of degraded riparian flora species in the Lawra Municipality in particular and Upper West Region in general. Going by pragmatism as a research philosophy, the study employed the mixed methods research approach in data collection, analysis, and presentation. Computed values of the Shannon Wiener Index (0.686) and Simpson's Index (1.5328) show that the riparian vegetation of the Black Volta Basin in the Lawra Municipality has dwindled due to livelihood activities as compared to the Shannon Index (1.6406) and Simpson's Index (3.5511) of the riparian vegetation of the Burkina Faso site across the Black Volta Basin. The reduction in vegetative cover of the Black Volta Basin in the Lawra Municipality is confirmed by satellite images which demonstrate dwindling riparian vegetation in the years 2020 and 2021 as compared to the years 2000 and 2001. The current study also discloses that restoration of the riparian vegetation of the Black Volta Basin in the Lawra Municipality is a collaborative effort of local and external stakeholders using measures such as complete ban on farming activities within the riparian zone, creating a buffer zone, promoting natural regeneration and a total ban on logging in the riparian zone. The study concludes that restoration of the degraded riparian vegetation of the Black Volta Basin of the study area is a panacea for sustainable development. It is recommended that by-laws to prevent logging of riparian tree species should be enforced by local and external stakeholders of the riparian vegetation of the study area.</p></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666765724000966/pdfft?md5=0371cee493625a8ada0127d3b53f667b&pid=1-s2.0-S2666765724000966-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142089293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this understudied environment, we present a comprehensive case study on microplastics in an urban lake from Baltic region of Northern Europe covering the seasonal dynamics of microplastics in surface water, deposition rate throughout one year in sediment traps and distribution of microplastics in dated sediment archive to determine the most representative environmental compartment for microplastic pollution monitoring. The following well-established microplastic research methods have been used: Manta trawling for surface water, trapping for assessing microplastics sedimentation rate and coring for sediments. Attenuated total reflection and micro-Fourier transform infrared spectroscopy methods were used to investigate the synthetic nature of identified particles. The sediment core chronology was based on <sup>210</sup>Pb and Bayesian Plum model revealing sediment layers to represent even the time before the beginning of plastic mass production (approximately 1950). The surface water microplastic concentrations were higher in summer (5.71 particles/m<sup>3</sup>) and gradually decreased towards winter (0.75 particles/m<sup>3</sup>); they were almost 25 times higher in more recent (2018) sediments than in the deeper layers referring to years prior to 1890. Surprisingly, microplastic particles were found in sediments before the year 1950. The microplastic deposition rate was 9.47 particles/cm<sup>2</sup>/year or 4.31 µg/cm<sup>2</sup>/year. The most abundant polymers were polyethylene, polystyrene and polypropylene, and the prominent particle shapes were fibres in surface water and fragments in sediments. Our results provide a baseline for evaluating future contamination level changes in highly urbanized area. We recommend the combination of surface water filtering with net and sediment trapping methods for monitoring microplastics in lakes since this method requires little time and financial resources for sampling and processing and produces information on temporal microplastic occurrence and deposition.</p></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666765724000954/pdfft?md5=4bca520a92522f88a11bcb1ad4488cdc&pid=1-s2.0-S2666765724000954-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142011833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The copper sulfide nanoparticles demonstrated high photocatalytic degradation efficiency of trypan blue (TB) and brilliant green (BG) dyes. The as-prepared nanoparticles efficiently removed lead(II) (Pb<sup>2+</sup>) and chromium(VI) (Cr<sup>6+</sup>) ions.

The optimal conditions for TB degradation were pH 10.91, 77.46 minutes, and 4.999 g/L, while for BG, they were pH 3, 70 minutes, and 5 g/L. For Pb<sup>2+</sup> removal, optimal conditions were pH 7.06, 100.38 minutes, and 0.94 g/L, and for Cr<sup>6+</sup> removal, pH 3.03, 168.20 minutes, and 0.98 g/L.

It is a daily activity essential for supplying the requisite energy and nutrients for living through food consumption. Exposure to air pollutants from cooking with solid fuels in domestic and commercial kitchens is a leading health risk in developing nations like Ghana. Real-time monitoring of gaseous pollutants (CO, SO<sub>2</sub>, NO<sub>2</sub>) was done during eight hours of occupational cooking in different cookstove kitchens of 14 Senior High Schools in the Kumasi Metropolis, Ghana. The traditional and improved cookstove kitchens were fueled by firewood whereas the briquette cookstove kitchens were fueled by palm kernel shell briquette. The observed median concentrations in the kitchens were 0.43–39.44 mg m<sup>−3</sup> for CO, 0.07–0.36 mg m<sup>−3</sup> for NO<sub>2</sub>, and 0.19–0.61 mg m<sup>−3</sup> for SO<sub>2</sub>.

To lower process time and to use green organic solvents, ultrasonically enhanced leaching is a valid alternative to conventional processing.

Conventional and ultrasonically enhanced leaching techniques were thus compared in terms of leaching efficiency, particle size distribution and morphological changes, demonstrating the beneficial effect of ultrasonic cavitation on mass transfer.

Since then, microplastics have been found in aquatic and terrestrial environments, the atmosphere, and inside the bodies of animals and human beings, including human lungs. The plastic particles’ contribution to environmental pollution is extensive, accounting for millions of metric tons of waste in the oceans and on land. As the world grapples with extensive microplastic pollution, significant progress is being made in preventing and addressing it. To this end, green microbiology has emerged as a potential approach for microplastic remediation. This article evaluates research on the viability of the use of microorganisms for this purpose, highlighting some microorganisms that have been used successfully in the remediation of microplastics, the mechanisms employed for this purpose, and the link of their use for microplastic remediation to sustainability. Finally, this article builds on current knowledge to identify potential future directions for research on the use of microorganisms for microplastic remediation.</p></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666765724000875/pdfft?md5=d5a55718cb454a99e73957c099dfd059&pid=1-s2.0-S2666765724000875-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141729695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
