Good air quality expected for Thursday

SINGAPORE - The 24-hour PSI reading for July 3 was between 27 to 35 at 4pm. The PM2.5 concentration levels was 19 to 24µg/m3, the National Environment Agency (NEA) said.

In an advisory, NEA said that the 24-hour PSI for Thursday is expected to remain below 50 and in the "Good" range. However, PM2.5 levels are expected to be slightly elevated.

Southwesterly or southerly low level winds are expected for the next few days. Thundery showers are expected on the morning of July 5.

Based on the 24-hr PSI and 24-hr PM2.5 forecast, the health advisory for this period corresponds to the PSI <100 band in the MOH Health Advisory for the General Public and Workers, as follows:

Healthy persons: Normal Activities

Elderly, pregnant women, children: Normal Activities

Persons with chronic medical conditions especially lung or heart disease: Normal Activities

The general public is advised to carry on with normal activities.

NEA noted that the health impact of haze is dependent on one's health status, the PSI (Pollutant Standards Index) level, and the length and intensity of outdoor activity.

Hence, reducing outdoor activities and physical exertion can help limit the ill effects from haze exposure.

The MOH health advisory for general public and workers provides general advice on the preventive measures that can be taken to reduce the health impact of haze when the air quality is poor.

Those who are not feeling well - especially those with chronic heart or lung conditions - should seek medical attention.
