Singapore’s drive for cleaner air [News]
By Woo Sian Boon, Today, 24 Aug 2012.
To ensure cleaner air in Singapore, the Government is raising emission standards for new petrol vehicles and improving petrol quality while increasing the frequency of updates on the Republic’s air quality.
Starting today, the National Environment Agency (NEA) will be reporting the Pollutant Standards Index (PSI) thrice daily at 8am, noon and 4pm, instead of once a day, to make air quality information more relevant.
The level of particulate matter (PM) 2.5 – a very fine pollutant which can cause respiratory problems – will also be reported alongside the PSI.
If the air quality deteriorates to the extent that it is likely to affect one’s health, advisories will be issued separately for the central, northern, southern, eastern and western sectors of Singapore. Previously, only one advisory was issued for the whole country.
