Using polluted regions in Africa as a model for understanding what species of wild animals and animals bred for meat are vunerable to chemical pollution - an environmental toxicological approach to tackling ecosystem conservation and food security problems

Research grant

Project Description

Currently, the extinction of wild animals and food shortages are urgent global issues. This research aims to 1) conserve biodiversity and ecosystems including wild animal species, and 2) ensure food security in the form of important food animals. It will use regions in Africa where pollution levels are already advanced to research the accumulating properties of pollution in wild and food animals and the biological defense mechanisms of different species, and identify wild animal species that are vunerable to chemical pollution and food animal species that are effective at excreting contaminated material.

Research record
Involved in sampling internal organs of chickens, an important food source, in South Africa from April 12-23, 2013. Has been analysing isotope ratios and the accumulating properties of heavy metals and agrochemicals such as DDT in both wild and food animals (hippos, buffalo, cows, goats, sheep, camels, chickens, and wild birds such as pelicans) in Zambia, Ghana, South Africa, and Ethiopia since May 2013. Carried out sampling focused on livestock in Nigeria in August 2013 (funded seperately). Has also carried out experiments on cloning and expression of CYP2C and CYP3A molecular species in some wild bird species and horses, an important food animal.
