PhD topic: Spatial mapping and modelling of heavy metals in Ghana

Lily Lisa Yevugah

Focus of PhD topic:

 

The overall aim of this research is to model the distribution of heavy metals (As, Mn, Cr, Cd, Cu, Ni, Pb, Zn and Hg) and to provide background information on the concentration of heavy metals in soil on a country scale (25km x 25km). Having background information serves as a reference for other works, showing the degree to which remediation action might be needed. The study gives a basis for effective policies to protect soils from long term heavy metal pollution.

PhD topic: Emission and distribution of mercury in and around some artisanal gold mining areas in Ghana: Environmental concentrations, fate, human exposure and health risk assessment

Focus of PhD topic:

 

My PhD focuses on emission and distribution of mercury in and around artisanal small-scale gold mining communities in Ghana. The project seeks to establish the levels of mercury in environmental media soil, air and water. The levels of mercury in the environment would be used to assess the level of mercury pollution/contamination in the ecological environment. Then a human health risk assessment would be performed to establish the risk posed to humans. Finally, environmental models would be used to predict future mercury loads in the environment based on scenarios.

PhD topic: Heavy metals and Xenobiotics in soil, water and sediment; Measurement and Modelling in the Pra river basin

Focus of PhD topic:

 

This research focuses on establishing the levels of mercury and heavy metal in the different matrices in the catchment of the Pra river basin to know the extent of contamination and compare results to that from the Volta basin- pristine site. The use of Spreadsheet-based Ecological Risk

Assessment for the Fate of Mercury (SERAFM) as a predictive tool to model future scenarios of

an increase, decrease or control of the activities in the catchment of the basin that results in the

release of metal contaminants into the basin will also be explored in this research.

PhD topic: Local scale assessment of heavy metals and xenobiotics in two e-waste recycling areas in Ghana.

Focus of PhD topic:

 

To quantify, at local scale, anthropogenic pollution due to heavy metals (Hg,

Cd, Cu, Cr, Zn, As, Mn, Pb) and xenobiotics (PAHs, PCBs) in soil, water and sediment from Dagomba

Line (a smaller e-waste recycling site in Kumasi) and a comparison with current concentrations from

Agbogbloshie (which is a well-known e-waste site in Accra). The human health risk from exposure to

current concentrations would be assessed and future trends of pollution would be modelled.

PhD topic: Management of artisanal small-scale gold mining in Ghana: An assessment of knowledge, formalization and receptivity to alternatives

Focus of PhD topic:

 

Most ASM activities though economically important, occupy a hazy world of informality coupled with increased pollution and destruction of the environment and threat to human health. The focus of the study is to assess the knowledge and perceptions of miners on the risks associated with small-scale mining. The increased risks of mercury as indicated in the conventional literature has propelled the introduction of cleaner technologies to minimise risks. Therefore, the study further assesses miners’ knowledge of available alternatives to mercury and their receptivity to adopting a safer and environmentally friendly alternative.
