Global treaty to control neurotoxin

OVER 120 nations have agreed to have legally binding measures to control the pollution by mercury, a neurotoxin. Formal negotiations for the treaty will begin in 2010.
The agreement, reached at the 25th session of the Governing Council of the UN Environment Programme (unep) in the Kenyan capital, Nairobi, is a change from previous years, when major powers, including the US, China and India, sought voluntary reductions. On February 18, they agreed to consider the binding treaty.
Some countries, including India, had earlier said a legally binding agreement is not necessary for unintentional mercury emissions. It was supported by China and Indonesia.
