The Ministry of Environmental Protection said on September 22 China will reevaluate and revise a series of environmental quality standards, including those for air, water, soil and noise, over the next five years.

Standards for pollution emission limits in some key industrial sectors will be established, while existing standards will be upgraded.

The ministry said it would launch special campaigns to deal with serious existing environmental problems, including air and soil pollution, garbage disposal and the pollution released by the heavy metal and chemical industries.
