Tibet Enjoys Clean Air
The Tibet Autonomous Region, in southwest China, now enjoys fairly clean air, according to the latest report on air quality issued by the regional Environmental Protection Bureau. This is a result of Tibet's efforts to protect its environment while speeding up economic development in recent years.
The Tibet Autonomous Region, in southwest China, now enjoys fairly clean air, according to the latest report on air quality issued by the regional Environmental Protection Bureau.
This is a result of Tibet's efforts to protect its environment while speeding up economic development in recent years, say bureau sources.
The report says that air pollution in Tibet is mainly caused by natural floating dust and the major pollutant is particulate matters.
Lhasa, the regional capital, is the biggest city in the region, with concentrated population and industries. However, monitoring results show that in 2001, Lhasa residents enjoyed 347 fairly clear days, and only 18 days that were slightly polluted.
Air in the Mt Qomolangma area is of the top quality, and according to monitoring results, there was no acid rain in Tibet last year.
Zhang Yongze, deputy director of the regional Environmental Protection Bureau, said that industrial waste gas emissions had increased as a result of rapid industrial development in the region in recent years. But, the content of sulphur dioxide and industrial dust in waste gas had dropped by a big margin, Zhang said.
Last year, Lhasa instructed 143 local bathhouses to swap coal-burning boilers for electric ones. Forty-four were closed for causing heavy pollution.
Li Chang'an, deputy mayor of Lhasa, said to date the city had closed three heavily polluting cement plants and told the rest to take effective measures to control pollution.
