Plastic cigar tips debris: Exploring use and disposal issues for Lake Erie beaches
2018
Hardy, Scott D. | Bartolotta, Jill
Great Lakes states are increasingly faced with questions regarding how plastic debris is impacting marine and coastal ecosystems. This is especially evident along the southern beaches of Lake Erie, where high population and industrial development have contributed to the plastics problem. In Ohio, the most common items found are cigarettes and other smoking related materials, including plastic cigar tips. Given the growing awareness of the issue, and the impact of plastics on beaches throughout the Great Lakes, a focus group convened to investigate strategies to help address the problem. The group was comprised of individuals with practical knowledge of plastic cigar tip use and disposal issues, including representatives of government agencies, nongovernmental organizations, community groups, and local academic institutions. This report represents the exploratory results of the focus group, complete with information regarding the what, why, and how of plastic cigar tip debris in the region, guidance on the material and social barriers to sustaining desired behaviors (cessation of use by minors and/or proper disposal), strategies to overcome those barriers, and suggestions for management and policy actions moving forward. Group members suggest that a combination of education and government-supported financial incentives may be the most effective approach, with community-based positive messaging backed by local taxes on smoking items that have plastic tips and rebates or other rewards for properly disposing of debris.

2011
Ahmad, Sheikh Saeed | Biiker, Patrick | Emberson, Lisa | Shabbir, Rabia
Nitrogen dioxide is an important gaseous air pollutant. It plays a major role in atmospheric chemistry, particularly in the formation of secondary air pollutants, and contributes to environmental acidification. A comprehensive assessment of NO2 levels in the atmosphere is required for developing effective strategies for control of air pollution and air quality improvement. Air pollution is a serious problem in all major cities of Pakistan and needs to be addressed to minimize detrimental effects on human health and urban vegetation. In this research, we focused on the monitoring of NO2 levels in the urban environment of Rawalpindi city. Because of the lack of expensive continuous sampling devices and to get a good spatial coverage of the NO2 concentrations in the study area, NO2 passive samplers were exposed at 42 different sites within the city limits of Rawalpindi from January to December, 2008. Samplers were exchanged every 10 days and the associated meteorological conditions like temperature, wind speed, rainfall and relative humidity were also monitored. The average NO2 concentration was found to be 27.46 ± 0.32 ppb. The highest values of NO2 were measured near to main roads and educational institutions due to intense flow of road vehicles. Moreover, the study showed that the values obtained for NO2 for all sampling points exceeded the annual limit value set by World Health Organization. So, this is very important to take different steps to control this before it becomes a serious hazard for people living in those areas.

2021
Shahbaz, Muhammad | Bashir, Muhammad Farhan | Bashir, Muhammad Adnan | Shahzad, Luqman
This study aims to provide a comprehensive knowledge map of tourism and environmental degradation literature review based on scientific articles published between 1999 and 2020. The study provides an overview of research, influential authors, and journals. The PR China has maintained the lead in academic research with the most contribution in academic research in recent years. Sustainability, the Chinese Academy of Sciences, and Katircioglu are the most productive journal, academic institution, and author in the field of tourism and environmental degradation, respectively. The degree of research contribution among researchers, institutional and national level, has an upward trend in recent years, but the research contribution among author level is higher than the institutional and national level. Furthermore, co-citation analysis suggests that research articles in the field are closely related. “Investigating the influence of tourism on economic growth and carbon emissions: Evidence from panel analysis of the European Union” authored by Lee is the most cited article. Our analysis of abstracts and keywords shows that climate change, ecotourism, carbon emissions, economic growth, and energy consumption are the hot spots of academic literature. We suggest that research collaboration between developed and developing nations should be promoted in creating sustainable tourism reforms.

2021
Bashir, Muhammad Farhan | MA, Benjiang | Abdurahman, Bilal | Komal, Bushra | Bashir, Muhammad Adnan
This study aims to provide a systematic literature review based on bibliometric analysis for scientific articles published between 1999 and 2019 extracted from Clarivate Analytics’ Web of Science (WOS) database. The current research project provides an overview of scientific publications, influential authors, and research journals. Our analysis reveals that the USA leads the academic research contribution, whereas China has provided the most research publications in recent years. Environmental and Resource Economics, University of London, and Barcena-Ruiz are the most productive journal, academic institution, and author in the field of environmental taxes, respectively. The degree of research contribution among researchers, institutional and national level, has an upward trend in recent years; however, the research contribution at the author level is higher than the institutional and national level. Furthermore, cocitation analysis suggests that research articles in the dataset are closely related. Pigou’s “The economics of welfare” published in 1920, is considered as the basic literature, and the “In defence of degrowth” authored by Giorgis Kallis is the most cited article. Our analysis of abstracts and keywords indicates that climate change, environmental taxes, double dividend, carbon tax, and environmental pollution are the hotspots within academic literature. We suggest that research collaboration between developed and developing nations and further coordination among environmental agencies such as IEA and IPCC will enhance the effectiveness of environmental reforms.

2019
Barnett-Itzhaki, Zohar | Eaton, Jarrod | Hen, Irit | Berman, Tamar
Desalination is an important strategy for adapting to the global shortage in safe drinking water. Israel relies heavily on desalinated water (over 50% of supplied drinking water). However, desalinated water may be more corrosive than water from other sources and may cause leaching of heavy metals from materials in contact with water. In this study, we measured heavy metal concentrations (copper, iron, lead) in 1379 drinking water samples in educational institutions in Israel and compared heavy metal concentrations in drinking water from different sources (desalination, groundwater, desalinated and groundwater mixture). 99.9% of the samples met the standard for copper (1400 μg/l), 99.7% for iron (1000 μg/l), and 99.6% for lead (10 μg/l). As expected, heavy metal concentrations were higher in first flush samples compared to flushed samples (significant findings for lead, copper, and iron). Heavy metal concentrations were not higher in desalinated water, or desalinated and groundwater mixture, compared to groundwater. In first flush samples, lead concentrations in groundwater were significantly higher than in desalinated-groundwater mixtures (p = 0.005). In flushed samples, lead concentrations in groundwater were higher than in desalinated-groundwater mixtures but the difference was not significant (p = 0.07). We suggest that regulatory requirements for stabilization of desalinated water and restrictions on lead content of plumbing materials appear to have been effective in preventing increased exposure to lead in desalinated drinking water in Israel. Further study should focus on potential heavy metal leaching in pure desalinated water samples.

2019
Kozajda, Anna | Jeżak, Karolina | Kapsa, Agnieszka
The aim of the literature review was to describe the environments where the presence of airborne Staphylococcus aureus was confirmed and to catalogue the most often used methods and conditions of bioaerosol sampling to identify the bacteria. The basis for searching of studies on S. aureus in the bioaerosol in different environments was PubMed database resources from the years 1990–2019 (May). The review included studies which were carried on in selected environments: hospitals and other health care facilities, large-scale animal breeding, wastewater treatment plants, residential areas, educational institutions, and other public places. The highest concentrations and genetic diversity of identified S. aureus strains, including MRSA (methicillin-resistant S. aureus), have been shown in large-scale animal breeding. The role of the airborne transmission in dissemination of infection caused by these pathogens is empirically confirmed in environmental studies. Commonly available, well-described, and relatively inexpensive methods of sampling, identification, and subtyping guarantee a high reliability of results and allow to obtain fast and verifiable outcomes in environmental studies on air transmission routes of S. aureus strains.

2020
Biswas, Aindrila
It has been widely acknowledged that environmental literacy can provide a strong foundation for future environmental responsiveness, as well as help in the transition towards more sustainable societies and healthy living. According to environmentalists and social scientists, behavioural intentions to sustainable consumption and lifestyle among citizens will help to nurture global environmental and economic sustainability and foster environment and human health development. The study tries to assess the adoption of sustainable lifestyle and healthy lifestyle practices through the designing and demonstration of quantitative method applying environmental literacy as a major predictor in the process which leverages environmental attitude towards such outcomes based on a literacy-sustainability-lifestyle-health modelling framework. The gap between learning and implementation should be addressed through integration of sustainability issues in awareness campaigns by government, NGOs, local bodies and educational institutions.

2017
Kabera, Telesphore
Due to the pressure on limited resources produced by a growing population and due to a decade of war, Rwanda is facing a major problem in environmental protection. Because of such problems, it seems only reasonable that environment-related courses should play an important role in the curricula of institutions of higher learning. The main aim of this research is to present a comprehensive picture of Environmental Impact Assessment (EIA) integration in graduate and undergraduate programs in Rwandese higher education institutions and to make recommendations for its improvement. During this study, two surveys were conducted: the first survey targeted Environmental Impact Assessment lecturers and the second survey was for Environmental Impact Assessment practitioners (including EIA certified experts and competent authorities). The study found that Environmental Impact Assessment is not well established in these institutions and it is not taught in some programs; civil engineering, for example, has no Environmental Impact Assessment courses. Recommendations to improve EIA education are proposed, such as requiring that a common core course in Environmental Impact Assessment be made available in Rwandese higher learning institutions.
