Monitoring Database of Environmental Mercury Concentration

Overview of the Database

The Minamata Convention on Mercury (hereinafter referred to as the “Minamata Convention”) is an international environmental treaty which entered into force in 2017, to protect human health and the environment from anthropogenic emissions and release of mercury and its compounds. In order to evaluate the effectiveness of the Minamata Convention, the Parties are required to cooperate with each other, and to collect the mercury monitoring data and other scientific data. The Ministry of the Environment of Japan (MOEJ) has been conducting monitoring surveys on the atmospheric mercury concentrations (background concentration) at Cape Hedo of Okinawa Prefecture and Oga Peninsula of Akita Prefecture, aiming at contributing to the domestic and international mercury management. This database compiles these survey results and supplementary information and makes them publicly available.
