Channel NewsAsia 16 Nov 07
SINGAPORE: The Pollutant Standards Index (PSI) hit 83 – within the moderate range – at 4pm on Thursday.
Residents from Bukit Panjang, Ang Mo Kio and Bishan called the Channel NewsAsia hotline to say that the sky was hazy.
The National Environment Agency (NEA) said it was due to the poor dispersion of air pollutants.
The pollutants accumulate because of light wind conditions during the current Inter-Monsoon period.
NEA added that the haze should clear when the wind conditions improve.
It said it is not uncommon for Singapore to experience brief periods of reduced visibility from time to time during the Inter-Monsoon period.
With the PSI at 83, no special precaution is needed, but those with respiratory ailments should consult their doctors before undertaking vigorous exercises.- CNA/so
