MANY public transport termini have poor air quality, according to a preliminary test done by the Government.
The Secretary for Planning, Environment and Lands, Tony Eason, said that from March to September this year the Environmental Protection Department (EPD) had surveyed the air quality in six of the 27 transport terminals with mechanical ventilation systems.
They were: Lam Tin transport interchange, Tsuen Wan MTR bus terminus, Sha Tin Central bus terminus, China-Hong Kong City terminal, Tai Po KCR station bus terminus, and Kai Tak Airport terminal.
The data had not been fully analysed, but preliminary indications were that in five of the six terminals one or more of Hong Kong's air quality objectives were not met, he said.
The main air pollutants were nitrogen dioxide, sulphur dioxide and particulates.
The poor air quality could be attributed mainly to inadequate or ineffective ventilation.
