Occupational and Environmental Medicine

Overview

Regarding cadmium (Cd), we are continuously conducting epidemiological investigations such as a survey of the regional accumulation of health effects caused by exposure to Cd (see the figure), by applying new methods including estimation of the Cd tolerance level using the Benchmark dose method. Regarding occupational health, we are conducting investigations of the rotating shift system, long working hours, and occupational stress to examine their relationship with health indices.
In the field of preventive medicine, research themes have developed from fatal diseases caused by significant environmental pollution, to effects on health and diseases in the general population due to low-dose exposure. We also intend to continue research in residents of areas that are not polluted by Cd, as well as company workers.
