The Minamata Convention on Mercury is an international treaty designed to protect human health and the environment from anthropogenic emissions and releases of mercury and mercury compounds. This Convention was a result of three years of meetings and negotiations, after which the text of the Convention was signed by delegates from 140 countries on 19 January 2013. The Convention is named after the Japanese city Minimata. This naming is of symbolic importance as the city went through devastating incident of mercury poisoning. It is expected that over the next few decades, this international agreement will enhance the reduction of mercury pollution from the targeted activities responsible for the major release of mercury to the immediate environment.
The Minamata Convention on Mercury was ratified in August 2017. As stated in the Conventionâ€™s preamble, protection of human health and the environment includes awareness â€œof health concerns, especially in developing countries resulting from exposure to mercury of vulnerable populations, especially women, children and future generations,â€ In Part II of the Conventionâ€™s Annex A, Parties are to take measures to phase down the use of dental amalgam, including (but not limited to) â€œtwo or moreâ€ of the nine provisions listed, and taking into account â€œthe partiesâ€™ domestic circumstances and relevant international guidance.â€
Nigeria signed the Minamata treaty on 10 October 2013 in Kumamoto, Japan, and ratified it on February 1st 2018. The Minamata Convention entered into legal force in August 2017. Addressing every major use of mercury, the Minamata Convention calls for a phase down approach to the use of mercury dental amalgam; see Annex A Part II. This is because it recognizes the fact that the road to achieving a total phase out of mercury dental amalgam begins with a progressive phase down with provisions for introduction of alternatives and monitoring of progress.
Health and Environment interaction
The WHO has reported that environmental Hazards are responsible for an estimated 25% of the total burden of disease worldwide. In Sub-Saharan Africa however, the proportion is higher (35%). This is probably due to poor development of infrastructures for monitoring and control of environmental pollution.
