Pollutants lessened in air, water

SHANGHAI reduced the emission of water-choking chemical oxygen demand last year by 8.74 percent and air-polluting sulfur dioxide by 15.05 percent.

The one-year reductions topped all the provinces and municipalities in the nation, Shanghai Environmental Protection Bureau said yesterday.

The city emitted 243,400 tons of COD and 379,000 tons of sulfur dioxide last year, meeting a 2010 target to reduce water and air pollution a year ahead of schedule.

However, coal-burning power plants' emission of sulfur dioxide is still high. Officials said big plants have installed de-sulphurization facilities for emission control, but small plants have been slower to do so.

"We will tighten management on small plants and speed up shut-off of small engine generators this year for emission control," said Wei Huajun, director of the bureau's pollution prevention and control department.

Local pollution control measures have paid off, with sulfur dioxide density dropping by 31.4 percent since 2008 and 42.6 percent from 2005. A total of 334 days last year were measured at good or excellent air quality.

The bureau also announced the boundaries of protection zones for four major drinking-water sources: Qingcaosha and Dongfengxisha reservoirs in Chongming County; the Chenhang Reservoir in Baoshan District; and the upper reaches of the Huangpu River in Qingpu District.

The zones are divided into three levels of protection, the most stringent to include fencing to prevent all activities not related to the drinking water supply, such as farming, shipping and fishing.

"It is the first time that we outlined the protection zones by enclosure to protect drinking water safety and quality," said spokeswoman Fang Fang. "Any land-use projects violating rules on drinking water protection in line with its level will be banned."
