Noriyuki Hachiya, Ph.D
Chief Scientist of Environmental Health Section and Environmental Welfare Promoter of the Region of Former Minamata Disease.縲€Main research interests have been in public health, particularly epidemiology, environmental health and risk evaluation of environmental chemicals. Recent research includes investigation on the social impacts of Minamata disease and risk management/risk communication of health effects of methylmercury. I think it is very important for the scientist to make every effort for the achievement of better understanding of the society on scientific accomplishments.
Subjects of study and affair
  • Study of risk governance on health effect of methylmercury
  • Technical transfer on mercury monitoring required for the measure to mercury pollution in the lake Managua, Nicaragua and methylmercury exposure study on resident of the coastal sites
  • Transmission of information on Minamata Disease, and organization of documents and materials in Minamata Disease Archives
  • Information service using hair Hg analysis
Study groups
