The society started in 1990. JEC made up of about 1,000 individual members including overseas and students, 16 public interest organizations and 66 private supporting corporations as of April, 2013. JEC has been working for the sound management of environmental chemicals through development of analytical techniques and waste treatment, understanding geochemical cycling of elements and molecules, and risk assessment. In addition, JEC has held international conferences for facilitating communication between researchers and stakeholders in different countries and exchanging knowledge related to environmental pollution by micro-pollutants by cooperating with societies in foreign countries: the first time in Hawaii in 1996, the second time in China in 2004 and the third time in Korea in 2010.
