Mercury Treaty

Objective: The Treaty aims at reducing global emission levels of the toxic heavy metal also known as quicksilver, which poses risks to human health and the environment.

Nations will be asked to ink the treaty next October in Minamata, Japan, in honour of the town’s inhabitants who for decades have suffered the consequences of serious mercury contamination.

Mercury is found in products ranging from electrical switches to thermometers to light-bulbs, to amalgam dental fillings and even facial creams, and large amounts of the heavy metal are released from small-scale gold mining, coal-burning power plants, metal smelters and cement production.

Mercury poisoning affects the body’s immune system and can lead to problems including psychological disorders, loss of teeth and problems with the digestive, cardiovascular and respiratory tracts. It also affects development of the brain and nervous system and poses the greatest risk to fetuses and infants.

As per UNEP : 

  • Concentrations in deeper waters have increased by up to 25%
  • Much human exposure to mercury is through the consumption of contaminated fish.
  • Around 200 tonnes of the substance are deposited in the Arctic every year.
