Dirt Clogs Unregulated Air Conditioning On City's Transport

WHILE the city tries to tackle the problems of air conditioning in Shanghai's public buildings, the cooling system on local buses and subways languishes, remaining laced with dust and other dirt.

One problem: There are no specific sanitation regulations for the transport system, on which millions of people ride each day.

"The vehicles easily catch dust and various other dirt traveling around the city," said Huang Weiming, a manager with local bus operator, Shanghai Bashi Co.

There are 16,000 air-conditioned buses operating citywide. But the cleaning and repair work is largely dependent on the bus companies themselves. Bashi said it usually conducts major repair and maintenance work three times a year.

Guidelines call for the air-conditioning filter to be cleaned every 10 days. But in a small test on nine bus lines, all the white cotton swabs used to rub the air outlet turned out black because of the dust.

Zhou Guanying, secretary general of the city air duct cleaning association, said that without regulations, it's hard to ask transport operators to clean up their act.
