Report of NIMDForum2009
Forum 2009
Date: February 18 (Wed), 2009: Study visit
            February 19 (Thu)〜February 20 (Fri), 2009: Forum
Venue: Minamata Disease Archives, National Institute for Minamata Disease
Main Theme: “ Methylmercury and n-3 poly unsaturated fatty acids (n-3 PUFA)
                      exposure from fish consumption”

 Our institute, National Institute for Minamata Disease (NIMD) conducts international forums (NIMD Forum) annually to discuss researches regarding mercury, and invites specialists from all over the world.
 This year, the specialists presented their latest researches concerning methylmercury and n-3PUFA from fish consumption. Especially, they discussed the concrete methods to reduce the risks of mercury with maintaining the merits from fish consumption, especially for pregnant women.
 This time, as Japanese and English simultaneous interpretation system was first introduced, the participants could understand and join to the discussion both in English and Japanese. Then, total of about 110 people (the largest number of participants in the last several years) took part in the Forum and they received useful information.
 We sincerely thank to all the speakers and the participants.
 The 9th International Conference on Mercury as a Global Pollutant (ICMGP) will be
held in Guiyang, Guizhow province, China in June 2009. In this conference, NIMD are going to organize a Special Session by our financial support. Therefore, this NIMD Forum 2009 was also held as a pre-session for the 9th ICMGP.
The participants of the Study visit could learn the environmental-control policies from Minamata city and nearby Minamata cities by the support of Kumamoto Prefecture as a Co-Organizer.
