FTIR spectra and XRD patterns validated the crystallinity and phase identification for as-synthesized powders.

The elemental composition of this nutrient-containing dust depends largely on the exposure region and time as well as on climate. Therefore, in this paper we report an analysis of atmospheric pollutions with a self-made low-cost bulk deposition sampler directed at sampling deposition via air transport and rainfall. We used the device in diverse environments - thus comparing an urban region, an area surrounded by forest and an area mainly dominated by agriculture. The total organic carbon (TOC) and total nitrogen (TN) amounts were selected as indicator parameters and analyzed in a biweekly rhythm for three and a half and two years, respectively. The TOC value responded to particulate matter in the urban area, especially significant were the influences of the New Year's firework in urban and pollen in the rural forest area. In contrast, the TN value was more under the influence of the nitrogen emissions in the agriculture-dominated area. However, the TN value did not correlate with the NOx values in the urban area because the atmospheric nitrogen emissions in the city might originate from various emission sources. Summarizing, the TOC and TN values of the self-made low-cost bulk deposition sampler were in good agreement with environmental events of their immediate surrounding. Moreover, the selected containers and sampling procedures are universally applicable to monitor and analyze organic as well as inorganic parameters (e.g. metal ions) of atmospheric deposition.</p></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":"17 ","pages":"Article 100583"},"PeriodicalIF":0.0,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666765724001017/pdfft?md5=96fdb5a5293bb14ff5a0612072fb22cd&pid=1-s2.0-S2666765724001017-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142137213","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 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":"17 ","pages":"Article 100578"},"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}

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 ²¹⁰Pb 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/m³) and gradually decreased towards winter (0.75 particles/m³); 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/cm²/year or 4.31 µg/cm²/year.
