Green light bulbs 'may pollute water'

GUANGZHOU: The widely publicized energy-saving bulbs, which now are a source of light in millions of Chinese households, may well be causing mercury pollution in many parts of the country.

Still, an official of the Guangdong provincial bureau of environmental protection said the department has "not come up with any concrete and effective measure to cope with mercury pollution" so far.
