I refer to the letter from Wilson Kwok headlined, 'Air let-down' (South China Morning Post, November 11).
In Hong Kong, air pollution is monitored in accordance with the highest international standards and practices. All air-quality monitoring stations in Hong Kong are designed, built and operated to meet the highest standards and specifications. The monitoring operation is fully accredited and subject to scrutiny under the Hong Kong Laboratory Accreditation Scheme, by overseas examiners as well as highly commended by international experts. Hence the measurements are fully reliable and can be used to compare directly with the measurements made and air-quality standards adopted in the developed countries.
Likewise, the air pollution index announced every day is developed and calculated using the same set of principles and practices adopted in most places of the world. It will enable the people of Hong Kong to understand our air-quality standards compared to other places.
Mr Kwok also raised concerns over air quality inside buildings. He may be glad to know that the Government has already commissioned a study on the subject that is approaching completion. The Government will consider the findings seriously and, if necessary, take any steps required to deal with the matter.
