Noriyuki Hachiya, Ph.D
Chief Scientist of Social Science Section.
My main research interests have been in public health, particularly in epidemiology, environmental health and risk evaluation of environmental chemicals. Recent research themes include investigation on social effects of Minamata disease and on adverse health effects and risk communication of the low level exposure to methylmercury. I think itfs very important for the scientist to take the responsibility for society on its understanding and accepting the scientific accomplishments.

Subjects of study and affair
  • Study on social impacts of Minamata disease and regional restoration
  • Social history in Minamata disease area
  • Study on the current living conditions of Minamata disease patients
  • Study on risk communication of low level exposure to methylmercury
  • Association of perinatal factors, postnatal developments and methylmercury concentration of cord blood in Tokyo/Sado cohort
  • Hair mercury analysis in Japan
Study groups
Social and epidemiological approaches to Minamata disease
Working group on risk recognition and information service
