Photocatalytic water treatment using nanomaterials has emerged as a promising and cutting-edge approach to address this pressing environmental challenge. In this work, a co-precipitation method was employed to synthesize europium (Eu3+) doped gadolinium metavanadate (GdVO4). The GdVO4:Eu3+ was encapsulated in polyvinyl alcohol (PVA). The GdVO4:Eu3+ and PVA-GdVO4:Eu3+ were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), Fourier-transform infrared (FTIR) spectroscopy, Raman spectroscopy, thermogravimetric analysis (TGA), photoluminescence (PL), and UV–visible spectroscopy (UV-Vis). The XRD, FTIR, and Raman spectroscopy results confirmed the formation of both GdVO4:Eu3+ crystals and PVA-GdVO4:Eu3+ nanocomposite. Both compounds’ photoluminescence spectra demonstrated effective energy transfer from the GdVO4 host to the Eu3+. Results obtained from the TGA indicate that PVA-GdVO4:Eu3+ nanocomposite is stable at a temperature of 330°C. Under UV irradiation, materials’ photocatalytic efficiency was examined regarding their ability to degrade Eosin Y dye in water. Results from the photocatalytic studies of the synthesized PVA-GdVO4:Eu3+ showed improved photocatalytic activity compared to GdVO4:Eu3+ under the same experimental conditions. When operating under ideal conditions of pH = 2, initial dye concentration of 30 ppm, a catalyst dosage of 200 mg, the degradation of Eosin Y surpassed 95% within 150 min of exposure to light.","PeriodicalId":29858,"journal":{"name":"Sustainable Environment","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136353232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study, grounded in environmental health literacy, investigated the practices, knowledge, and beliefs of 24 informal educators housed in varied agencies and organizations in a southeastern US state. Participants described a range of educational activities and identified organizational constraints on their education about fish consumption advisories, which varied by organization type. Their knowledge of relevant environmental health concepts was incomplete, and they described health and teaching beliefs consistent with limited focus on advisory education. Local government and nonprofit educators were well positioned to educate anglers about advisories, due to their freedom to design and deliver instruction and their regular contact with anglers. Educators in wildlife agencies had more contact with anglers and were identified as potential conduits given their interactions, but organizational constraints (such as educators’ ability to choose content/pedagogy and conflicting missions of agencies) would need to be addressed.","PeriodicalId":29858,"journal":{"name":"Sustainable Environment","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135536434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tests for physiochemical parameters and germination tests were performed. It was realized that at 300°C biochars produced had high nitrogen, organic matter, bulk density, biochar yield, and longer root lengths. The results indicate that municipal food waste biochars produced at three temperatures were suitable for use as fertilizer. However, biochar produced at a moderately lower temperature is favourable for agriculture purposes, FWB1–300°C and FWB2–450°C obtained moderate pH and ash levels and so are less toxic to the growth of plants.","PeriodicalId":29858,"journal":{"name":"Sustainable Environment","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134957675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This classification is known as governance modes. This article addresses municipal solid waste (MSW) governance inside and outside protected areas based on the Sepultura Biosphere Reserve (REBISE) case in Chiapas, Mexico. We conducted semi-structured interviews and a content analysis of laws and municipal regulations to identify the stakeholders and institutions that operate at community and municipal levels. Our research is a first effort to analyze the modes of MSW governance and offers a spatially explicit classification to reveal the spatial differences in how MSW is governed. The populations close to the capital city and the main roads have a multiplicity of mechanisms and modes of MSW governance, which contrasts with distant communities located within the REBISE. This work illustrates the gaps where municipal authorities are unable to fulfill their obligations and the potential of market and collaborative mechanisms. Characterizing governance modes through spatially explicit thematic maps reveals the interactions between stakeholders and formal and informal institutions, which could contribute to territorial planning toward more effective MSW governance.","PeriodicalId":29858,"journal":{"name":"Sustainable Environment","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134960156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the synthesis of magnesium oxide (MgO) from magnesium-rich Cucurbita pepo (pumpkin) seeds for a precursor solution as a reducing agent via an eco-friendly method for the first time. The pumpkin seeds were ashed at 550°C for 6 h and subjected to acid-leaching. Mg(OH)2 was then precipitated using an aqueous solution of 2.0 M NaOH. The Mg(OH)2 was then calcined at 550°C for 4 h to obtain MgO. Physicochemical properties (i.e. proximate analysis, elemental composition, electrical conductivity (EC), pH) and selected heavy metals (i.e. Pb, Fe, As, Cd, Cr, Hg, Cu, and Ni) analyses were conducted on the seed samples and as-synthesized MgO. X-ray fluorescence (XRF), X-ray diffraction (XRD), Fourier-transform infrared (FTIR), citric acid test (CAT), and acid neutralization capacity (ANC) tests were techniques used to characterize the synthesized MgO. The results revealed the percentage yield of the MgO to be 23%. The pH of the as-synthesized MgO was recorded as 10.63. XRF studies showed that MgO made up 75.1% of the total weight synthesized. XRD results showed the presence of crystalline cubic structures of MgO. FTIR results showed a peak at 584 cm−1 which confirmed the formation of MgO. The produced MgO was highly reactive, with a CAT time of 2 s. The ANC of the MgO was high at 22.77 mol+/kg. Also, metal concentrations such as Fe, Cu, Cd, Ni, Pb, Hg, As, and Cr in MgO were below the WHO stipulated limits of 350, 36, 0.8, 35, 85, 0.03, 40, and 100, respectively. This implies its suitability for soil remediation purposes. Results indicate that the as-synthesized MgO from Cucurbita pepo (C. pepo) seeds could be used for several applications due to its high alkalinity, reactivity, and fast CAT time.","PeriodicalId":29858,"journal":{"name":"Sustainable Environment","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136236961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper aims to explore the trends and contributions of scientific publications to R&CC about South America. Through the examination of 330 papers listed in the Web of Science database, the current study conducted a thorough overview between 1998 (oldest study) and 2021 (cut-off date) of bibliometric networks (keyword co-occurrence map, co-authorship maps, and author co-citation map) and multivariate statistical models (principal component analysis, compositional linear model). We address main communication factors, links between communication factors and countries, main academic cooperation networks, determinants of publication trends, and most cited authors. 28 R&CC factors were mapped and their relative importance to various hazards was examined. Most of these factors were intended to strengthen the communication system and increase risk knowledge of vulnerable people. Chile, Colombia, and Ecuador were mostly focused on strengthening R&CC. Brazil and Argentina were best represented with health and exposure to pollutants communication. Publications on R&CC are determined by the level of wealth, tourist arrivals, and the number of people affected by disasters. The compositional analysis revealed that the behavior of publications determinants could have opposite tendencies depending on the threats’ multidimensionality. To the best of our knowledge, this is the first R&CC study on South America to use CoDA in a bibliometric analysis.","PeriodicalId":29858,"journal":{"name":"Sustainable Environment","volume":"54 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88377486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
