SINGAPORE - Those planning to attend election rallies on Tuesday (Sept 8) night may want to take note.

The three-hour Pollutants Standard Index (PSI) at 5pm was 132. It breached 100 at 2pm, and was 127 at 4pm.

The 24-hour PSI at 5pm was between 91 and 106.

A 24-hour PSI reading of above 100 is considered unhealthy, while one between 51 to 100 is moderate.

When the 24-hour PSI inches above 100, the authorities advise healthy people to reduce prolonged or strenuous outdoor activity. There is no health advisory attached to the three-hour reading.

The elderly, pregnant women and children should do as little of such activity as as possible, while those suffering from chronic lung or heart disease should not engage in these activities.

NEA said in advisory on Monday evening that the prevailing winds are forecast to blow from the south or south-west on Tuesday.
