Sai Kung District Council members had air quality measurements taken at six public transport interchanges in the Tseung Kwan O area. The results are now in.
One member described the air quality for those waiting for buses as “like living in “large-scale gas chambers.””
The results showed that all interchanges exceeded the WHO guidelines for PM2.5, some over 5x the maximum recommended 10 µgm/m³. South Horizons at “51”, is the highest among the six interchanges tested, followed by Lam Tin interchange, where the PM2.5 concentration is “50.”
The councillors said over the years they have had many complaints from residents about having to wait in such bad environments, but because transport interchanges are the responsibity of a number of government departments, no one was interested in solving the fundamental problems.
