Introduction to Grant Projects

Veterinary Medical Science, Graduate School of Veterinary Medicine, Hokkaido University Professor Mayumi Ishizuka

Construction of an environmental pollution database and a field toxicology network based on joint surveillance in Africa (preliminary survey)

Research grant

Project Description

We will conduct a preliminary survey ahead of a research study on environmental pollution by toxic chemical substances to be conducted jointly with several African universities/administrative authorities and to be followed by database construction. Here, we model three African countries (Zambia, toward the south; Kenya, the east; and Ghana, the west), collecting environmental and biological samples for analyses of environmental pollution and its effects. We hold a symposium at the University of Zambia, to which we invite environmental toxicology scholars, graduate students, and concerned officials from approximately 10 African countries. By this, we are to build a network of individuals active in the field of environmental toxicology.
