SINGAPORE – Air quality deteriorated over Singapore on Sept 15, with the Pollutant Standards Index (PSI) reaching unhealthy levels in all parts of the country in the early hours of the morning before improving slightly.
Previously, bouts of unhealthy haze were detected only in certain parts of the country.
The PSI, a measure of air quality here, registered readings of between 104 and 154 at 6am on Sept 15, before dropping slightly to between 92 and 131 at 6pm.
Air quality is considered moderate when PSI levels are between 51 and 100, and unhealthy when PSI readings are above 100.
At that level, healthy people should reduce prolonged or strenuous outdoor activities, while those with chronic heart and lung disease should avoid such activities.
Unhealthy levels of haze were first detected in central Singapore on Sept 4. Since then, hazy conditions have prevailed across Singapore.
The PSI on Sept 16 is expected to be between the high-moderate to mid-unhealthy range, said the National Environment Agency.
Some organisations have implemented measures to protect people against the haze.
The Straits Times understands that Outward Bound Singapore, an adventure camp for students, was cancelled for CHIJ St Nicholas Girls’ School students due to the worsening PSI on Sept 14.
The Singapore Hockey Federation (SHF) said it will suspend hockey matches in the men’s leagues if the PSI exceeds 100.
This is according to SHF’s own haze protocol, introduced last week when conditions started worsening. This will be applied to matches in the ongoing Divisions 3 to 5, which started in July at the Sengkang Hockey Stadium. The next round is slated to take place on Sept 19.
The protocol is more stringent than the advisory from national sports agency SportSG, which recommends that programmes and activities in outdoor and non-air-conditioned facilities be suspended when the PSI is above 200.
SHF president Aw Bang Hui said the federation decided on stricter measures as there are players who are in their 50s and 60s.
He said: “We are monitoring the situation closely and will actively apply contingency measures, depending on how haze conditions progress over the coming weeks. Players’ health and safety are of utmost importance to us and we do not take things lightly.”
