The aim of this study was to assess the potential use of Calendula officinalis for soil Copper (Cu) phytoremediation in the presence of different types of chelating agents (Ethylene Diamine Tetra-Acetic Acid (EDTA), Citric acid (CIT), and Tartaric Acids (TAR)) at different levels of Cu in a calcareous soil. Methods: To investigate the effects of stress caused by the use of chelating agents on biochemical changes of C. officinalis, the activity of some antioxidants of C. officinalis (Superoxide Dismutase (SOD), Catalase (CAT), Ascorbate Peroxidase (APX), Peroxidase (POD), and Polyphenol Oxidase (PPO)) was evaluated. Results: As results, C. officinalis showed an increase in shoot and root Cu concentration in the presence of all chelating agents compared to the control. The highest accumulation of Cu in the root/shoot was observed in EDTA-treated plants. However, an increased Cu level in plant parts (due to consuming of EDTA) was corresponded to lower dry weight in shoot and root; higher H2O2 and malondialdehyde (MDA) contents, and antioxidant activity (APX, PPO, CAT, SOD, and POD) in plants compared to the control treatment. On the contrary, the application of CIT and TAR primarily increased shoot and root dry weight and Cu concentration. Conclusion: Generally, the results of this study could be suggested that plants possess a well-organized resistance mechanism against oxidative stress caused by using of CIT and TAR.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91341116","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 cross-sectional, descriptive study aimed to measure the annual effective dose of natural background radiation in 93 schools in two districts of Hamadan, Iran in the winter, spring, and autumn of 2015-2016. Among the public schools in Hamadan, the schools located in district one with 1.41±0.079 mSv and district two with 0.955±0.04 mSv had the highest and lowest mean equivalent annual dose caused by natural radiation (γ rays) in a closed space, respectively. The mean equivalent annual dose caused by natural radiation in the closed space of all the public schools in districts one and two of Hamadan was estimated at 1.20±0.07 mSv as separated by geographical directions. In addition, the highest mean dose caused by natural gamma rays in the closed space of the school buildings constructed for more and less than 40 years was 1.42±0.22 and 1.42±0.15 mSv, respectively, and the rate of the effective annual dose of the public schools in Hamadan was determined to be 0.83 mSv as separated by district. The equivalent effective annual dose and risk of gamma ray cancer in the lifespan of the public school students in Hamadan was higher than the global average.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78946940","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}

Addis Ababa, the capital city of Ethiopia faces rapid urbanization leading to overcrowding and the development of shantytowns and poor neighborhoods. The general aim of this study was to appraise the present dry waste service provision of Addis Ababa. This study used an integrative literature review method with critical analysis to investigate the current solid waste management status in Addis Ababa. The results of this study show that the delivery of the service does not keep pace with the city's solid waste generation and the city's municipal disposal of solid waste is found in actual, low status and spatial coverage. This humble status of city garbage management is also heightened by three critical factors, i.e. poor institutional structure, inadequate disposal site and transfer station, and poor households' solid waste handling practices. Besides, the city households dominantly created decomposable solid wastes (60%) through generation amount of 0.45 kg/person/day and the main source are residential wastes, which account for 76% of the total waste. The sudy concluded that, the main problem with the incompetence of this sector in the city was the lack of trained labor and inadequate service delivery. In order to improve the status, there should be awareness creation, improvement of the city government, and implementation of an incorporated method to the management of metropolitan solid waste that respects and involves all stakeholders in the metropolis.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"355 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82610294","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 used the Delphi method combined with vision analysis to analyze the advanced energy fields and gain insights into the development trends of energy technology towards 2035. The Delphi survey convened 762 domestic experts to predict the development demands and trends of advanced energy technology, and to identify important technology topics. A key list, including 91 technology topics in 9 sub-fields, was analyzed with respect to promoting economic growth, improving quality of life, and safeguarding national security. Furthermore, we conducted a research on these technology topics in context of technology research and development (R&D) level, leading countries, technology realization possibility, and constraints. The results from the Delphi survey show that the R&D level of China’s advanced energy technology is still at an elementary stage, and China, significantly, lags behind the US and the EU in the fields of advanced energy. These results reveal that insufficient R&D investment is the primary factor restricting the technology development in China’s advanced energy, though human resources, infrastructure, regulations, policies and standards also play significant roles in restricting technology development. The results from the Delphi survey may serve as a reference and help in exploring the development path of low-carbon transformation and achieving goals for addressing climate change in China.","PeriodicalId":14962,"journal":{"name":"Journal of Advances in Environmental Health Research","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85142666","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}
