Three-hour PSI on Monday morning inches into unhealthy range

AsiaOne | Monday, Nov 3, 2014

It was another hazy morning on Monday as the three-hour Pollutant Standards Index (PSI) climbed into the unhealthy range of 103 at 8am.

The 24-hour PSI reading at 8am was 102-111, an increase from the PSI of 88-96 at 1am.

The National Environment Agency (NEA) said on Sunday that the haziness is due to smoke haze being blown in from Sumatra by prevailing southerly winds.

Hazy conditions can still be expected today, as the prevailing winds are expected to blow from the south or southwest.

NEA added that the health impact of haze is dependent on one's health status, the PSI level and the length and intensity of outdoor activity. Reducing outdoor activities and physical exertion can help limit the ill effects from haze exposure.

Given the air quality forecast for the next 24 hours, people in good physical condition are advised to reduce prolonged or strenuous outdoor activities.

Those who do not feel well should seek medical attention. This is especially so for the elderly, pregnant women, children and those with chronic lung or heart diseases.

NEA said that it will continue to monitor the weather and haze situation in the region, and update the public when necessary.
