Acknowledgement / Funding Declaration We wish to acknowledge the support of the ARRA Framework Programs for Global Health Signature Innovations Initiative (R24 TW008798-01). We would also like to express our gratitude to the University of Virginia and University of Venda students and the community members who assisted in the data collection which informed(More)
The persistent poor access to safe drinking water in low-income regions necessitates the development of low-cost alternatives to available yet expensive water treatment technologies. To address this need, this research investigates the development of a biofilter using the seeds of Moringa oleifera (MO), an indigenous tree in many low-income countries. The(More)
Illicit drug use is a perennial societal problem that has serious ramifications on the health and socioeconomic well-being of a society. Its identification and estimation in communities is difficult because of the privacy laws and doctor-patient confidentiality agreements, which may limit the availability of reports and data. Various analytical strategies(More)
The failure to remove tetracycline (TC) in most conventional wastewater treatment systems results in the discharge and accumulation of TC in the environment, which in turn, increases the potential for developing TC-resistance in naturally occurring microorganisms. Thus, there is a need to explore other processes that can enhance TC degradation during(More)
Access to safe water continues to be a serious health concern across the globe, particularly in the rural areas of developing nations. Inadequate standards and practices for treating and storing drinking water have increased the incidences of illnesses and mortalities due to waterborne diseases and contaminants. In this paper, we assess the viability of(More)
Although the Region of Waterloo implements a waste recycling program as part of its compliance with the 2004 Ontario Waste Diversion Goal a large fraction of its municipal solid waste ends up in the landfill. Landfill waste disposal adversely impacts the environment through the release of air pollutants and greenhouse gases to the atmosphere, and through(More)
Due to the high costs associated with laboratory analysis, load estimation of pharmaceuticals is necessary to identify compounds that may have high influent and effluent concentrations in wastewater treatment plants (WWTPs). The load estimation model presented in this paper was developed to estimate the influent concentration of prescription and(More)
Untreated surface water and groundwater are the primary sources of drinking water in many parts of the world, particularly in low-income regions. In these communities, the availability of low-cost water treatment technologies is especially critical in reducing incidences of waterborne diseases. In the present study, we explore the use of Moringa seeds for(More)
Depression is a major and costly global health burden that affects millions of people. The current diagnostic screen for depression relies on subjective structured interviews, but there is growing interest in exploring objective methods that involve depression biomarkers. In the current paper we perform a systematic review of recent articles on depression(More)
Nitrates, phosphates, and many other anionic chemical species are among the most problematic and widespread contaminants in water sources. Currently, technologies for removing them in water involve biological and physico-chemical processes. In this study, we test the extent to which the cationic protein from Moringa Oleifera (MO) seeds can effectively(More)
