Analysis of heavy metals and pathogen levels in vegetables cultivated using selected water bodies in urban areas of the Greater Accra Metropolis of Ghana.

Open-surfaced water sources have been used to irrigate vegetable farms in cities. Open-surface water often contains unmonitored concentrations of health-threatening contaminants that pose health risks, especially when used to produce vegetables for human consumption. However, information on levels of heavy metals and faecal coliform bacteria in such vegetables in selected sites, especially in Greater Accra Metropolitan Area (GAMA) of Ghana is rare.

Challenges of adopting sustainable technologies in e-waste management at Agbogbloshie, Ghana.

The study investigated why sustainable technologies are not used to collect, dismantle and sell e-waste at Agbogbloshie given the risk of injury and extensive environmental pollution associated with handling of electronic waste. The study objectives were to examine the nature of technologies adopted to manage e-waste, assess challenges faced in adopting sustainable technologies; determine the missing links between formal and informal e-waste workers. Research questions were; what is the current level of technology adopted to manage e-waste and challenges limiting the adoption of sustainable technologies; and what are the missing links between the formal and informal sectors that limit adoption of sustainable e-waste management strategies.
