Deal on mercury:
A new global treaty adopted by 140 nations will cut mercury pollution from mining, utility plants and a host of products and industrial processes. It sets limits on mercury emissions and encourages shifts to alternatives. Mercury is released from artisanal gold mining (pic), coal-powered plants, and from discarded electronic or consumer products such as electrical switches, thermostats and dental amalgam fillings. It is also found in batteries, paints and skin-lightening creams.
