Implications of Dynamic Interactions between Meteorological Patterns and Surface Water Quality on environmental health—A Case Study of the Nairobi River

引用

Journal of Geoscience and Environment Protection 2024年第5期12卷 113-146页

作者： Haron Safari Hongbin Chen Edwin Kipkirui Duncan Mbuge College of environmental Science and Engineering Tongji University Shanghai China National Engineering Research Center for Urban Pollution Control Shanghai China College of environmental and Biosystems Engineering University of Nairobi Nairobi Kenya

Urban areas face significant challenges in maintaining water quality amidst increasing urbanization and changing climatic patterns. This study investigates the complex interplay between meteorological variables and water quality parameters in Nairobi City, focusing on the impacts of rainfall and temperature on surface water quality. Data from multiple sources, including the Water Resources Authority, Nairobi Water and Sewerage Company, and the World Bank’s Climate Change Knowledge Portal, were analyzed to assess the relationships between meteorological variables (rainfall and temperature) and water quality parameters (such as electroconductivity, biochemical oxygen demand, chloride, and pH). The analysis reveals varying impacts of rainfall and temperature on different water quality parameters. While parameters like iron and pH show strong relationships with both rainfall and temperature, others such as ammonia and nitrate exhibit moderate relationships. Additionally, the study highlights the influence of runoff, urbanization, and industrial activities on water quality, emphasizing the need for holistic management approaches. Recommendations encompass the establishment of annual publications on Nairobi River water quality, online accessibility of water quality data, development of hydrological models, spatial analysis, and fostering cross-disciplinary research collaborations. Implementing these recommendations can enhance water quality management practices, mitigate risks, and safeguard environmental integrity in Nairobi City.

environmental health perspectives for low- and middle-income countries

Global health Journal 2022年第1期6卷 35-37页

作者： Xiaoming Shi China CDC Key Laboratory of Environment and Population health National Institute of Environmental HealthChinese Center for Disease Control and PreventionBeijing 100021China

In recent decades, the ecological environment has been increasingly challenged by the development of global industrialization and urbanization all over the world, even as global attention for health has raised dramatically. Common global environmental issues, such as air pollution and noise pollution, are associated with lasting impacts on health and contribute significantly to the overall burden of disease. Moreover, a global disparity exists between the burden of such environmental health issues and the global resources available to address this issue. To alleviate the environmental health impacts and ensure a sustainable future for human beings, China has made an important contribution to improving access to ecological protection, environmental governance, patriotic health campaigns, smart city construction, and so on. Experiences gained in China may be useful for some other countries, particularly the low- and middle-income countries with limited sources.

Planning for health: Complexity of environmental health and Planning Responses

引用

China City Planning Review 2018年第1期27卷 32-40页

作者： Liu Zhengying Yang Dongfeng Liu Jinxin Department of Urban Planning and Design Dalian University of Technology

China's rapid urbanization has led to increasing environmental health problems, which poses great challenges to urban sustainable development. In order to explore the scientific issue of planning for health, this paper firstly analyzes the challenges of spatial planning caused by environmental complexity in terms of health risk, environmental impact, and residents' behavior. And then it puts forward an analytic framework that includes three basic modules, i.e., theoretical model, regional health risk identification, and planning performance assessment, thereby finally proposing six spatial planning strategies according to the objectives of health protection, health promotion, and health equity, on the basis of the actual situation of health risk exposure, environmental friendliness, and the aging level in different cities of China.

Characterization of Wastewater in School Environments for an Ecological Treatment Solution: A Case Study of Ndiebene Gandiol 1 School

引用

Journal of Water Resource and Protection 2024年第1期16卷 27-40页

作者： Falilou Coundoul Abdou Khafor Ndiaye Abdoulaye Deme Polytechnic Institute of Saint-Louis Gaston Berger University Saint-Louis Sénégal Applied Sciences and Technologies Training and Research Unit Gaston Berger University Saint-Louis Sénégal

The study conducted at Ndiebene Gandiol 1 school in Senegal has unveiled serious environmental and public health challenges. The wastewater analysis revealed high levels of Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), and fecal coliforms, signaling potential risks to the well-being of students and staff. This situation mirrors a wider issue in rural educational settings, where inadequate sanitation persists. Intensive wastewater treatment options are known for their effectiveness against high pollutant loads but are resource-intensive in both energy and cost. Conversely, extensive treatment systems, while requiring more land, provide a sustainable alternative by harnessing natural processes for pollutant removal. The research suggests a hybrid treatment approach could serve the school’s needs, balancing the robust capabilities of intensive methods with the ecological benefits of extensive systems. Such a solution would need to be tailored to the specific environmental, financial, and logistical context of the school, based on comprehensive feasibility studies and stakeholder engagement. This study’s findings underscore the urgency of addressing sanitation in schools, as it is intrinsically linked to the health and academic success of students. Quick, effective, and long-term strategies are vital to secure a healthier and more prosperous future for the youth. With proper implementation, the school can transform its sanitation facilities, setting a precedent for rural educational institutions in Senegal and similar contexts globally.
