World comes together to tackle mercury poisoning

The world’s first Convention to protect the environment and human health in close to a decade, the Minamata Convention on Mercury, has entered into force , committing its 74 parties to reducing the risks to human health and the environment from the harmful release of mercury and mercury compounds. Mercury is recognized to be particularly harmful to unborn children and infants.

Governments that are party to the Convention are now legally bound to take a range of measures to protect human health and the environment by addressing mercury throughout its lifecycle. This includes banning new mercury mines, phasing-out existing ones, and regulating the use of mercury in artisanal and small-scale gold mining, manufacturing processes, and the production of everyday items such as cosmetics, light bulbs, batteries and teeth fillings.

The convention also seeks to reduce emissions as side effects from other industrial processes, such as coal-fired power stations, waste incineration, cement clinker production, and contains measures on the interim storage of mercury, on mercury waste and on measures to reduce the risks of contaminated sites.

“The Minamata Convention shows that our global work to protect our planet and its people can continue to bring nations together. We did it for the Ozone layer and now we’re doing it for mercury, just as we need to do it for climate change – a cause that the Minamata Convention will also serve. Together, we can clean up our act,” said Erik Solheim, head of UN Environment.

There is no safe level of exposure to mercury nor are there cures for mercury poisoning, which at high levels causes irreversible neurological and health damage. Unborn children and babies are the most vulnerable, along with populations who eat fish contaminated with mercury, those who use mercury at work, and people who live near a source of mercury pollution or in colder climates, where the dangerous heavy metal tends to accumulate.
