A data-intensive framework for evaluating ecological and human health impacts of soil potentially toxic elements (PTEs) in the mining-endemic region of Singida, Tanzania.

Uncontrolled soil contamination by potentially toxic elements (PTEs) poses serious threats to environmental and public health in mining-intensive regions. Against this background, this study assessed the distribution, sources, ecological impact, and human health risks of eight PTEs (Cr, V, Zn, Pb, Ni, Cu, Co, As) using 1,884 soil samples collected across Tanzania's Singida Region. Samples were analysed with Inductively Coupled Plasma Mass Spectrometry (ICP-MS).

Urban Noise Pollution in Kumasi Metropolitan Assembly, Ghana: Implications for Public Health and Quality of Life.

This study focused on urban noise pollution in the Kumasi Metropolitan Assembly, Ghana, examining its implications for public health and quality of life. Five submetropolitan areas: Subin, Bantama, Manhyia North, Manhyia South and Nhyiaeso were selected to represent different neighbourhood types: commercial, residential and mixed-use zones. Ambient noise levels were monitored using a JD-801A sound level meter.

Comparative analysis of the effectiveness and efficiency of formal and informal waste collectors in urban waste management system.

Effective and efficient waste collection and management is critical to achieving sustainable cities and communities, public health, and sustainable development. This notwithstanding, the rapid and ever-increasing rate of urban waste generation in developing countries has led to the emergence of a dual system of formal and informal waste collection schemes with unclear effectiveness and efficiency. This study compared the operational effectiveness and efficiency of formal and informal waste collectors in the urban waste management system in Ghana.

Healthcare waste management in the Tamale Central Hospital, northern Ghana. An assessment before the emergence of the COVID-19 pandemic in Ghana.

Healthcare waste (HCW) poses several environmental and public health challenges. However, much attention has not been given to its management. The present study sought to assess the healthcare waste management (HCWM) practices in the Tamale Central Hospital (TCH) by characterizing and measuring the quantities of waste generated and the associated implications.

Sachet water quality and Vendors' practices in Damongo, northern Ghana during the emergence of SARS-CoV-2 using multivariate statistics, water quality and pollution indices, and panel assessment.

The emergence of the SARS-CoV-2 has affected several production services including the water production and delivery processes. This study considered sachet water quality during the advent of the SARS-CoV-2 pandemic using multivariate statistics and Water Quality Index, Water Pollution Index and, hygienic and sanitation practices of sixty-two (62) sachet water vendors using a panel assessment approach. The findings showed that vendors did not adhere to proper hygienic practices as ninety-four (94%) of them did not have health clearance, ninety (90%) did not frequently wash their receptacles for selling daily, and most of them stored and sold in unhygienic environments.

Irrigation water quality and its impact on the physicochemical and microbiological contamination of vegetables produced from market gardening: a case of the Vea Irrigation Dam, U.E.R., Ghana.

The rationale for this study was to assess the physicochemical and bacteriological qualities of the Vea irrigation water and resultant effects on the quality of fresh vegetables produced in the area and associated implications for consumers' health. A total of 45 water samples were collected from the reservoir and canals. Also, 16 vegetable samples comprising four samples each of tomatoes, carrots, spring onions, and cabbages were collected from four farms with installed irrigation systems fed by the Vea Dam.
