I refer to the news article on Today Online – http://www.todayonline.com/singapore/24-hour-psi-reading-betterreflection-haze-impact-health
“The health impact of the air pollutants is determined by both the concentration and the duration of exposure. When we measure the health impact, the 24-hour measurement is a better reflection of the total exposure of the individual to particulate matter,” said Ms Fu, who was standing in for Environment and Water Resources Minister Vivian Balakrishnan, who was flying back from a ministerial meeting in Jakarta.
At this point of time, our leader is still thinking of altering the figures, and asking us not to trust what we see at the moment. They even wants to steal the rights of our own senses.
What did a real doctor suggest?
“People should be assessing the PSI level right before they go out, to see if the level at that particular hour poses a threat. An average figure for the whole day may not be that reflective, as the figures can fluctuate wildly throughout the day. The key is spot PSI.” Dr Lim Ing Ruen, an ear, nose and throat surgeon at Mount Elizabeth Medical Centre.
And a comment by a top commentor, Seldom Bin Laid: “next time, when I’m stopped by the traffic police for speeding, I’ll ask them to look at my average driving speed for the last 24 hrs as a more accurate reflection of my driving speed. Can?”
