Indoor vs. Outdoor air
Friday, 23 March 2007, Written by Julien   
Spring is coming, and with the spring come the winter babies, future mothers see their bellies getting rounder and anyone can see excitement on fathers' faces. I was chatting with one of those future fathers recently and I realized that most people do not know anything about indoor air pollution.

So let's start from basics and play the Spot the difference game! What are the differences between indoor and outdoor?
  • you spend 80% of your time indoor, and a merely 20% outdoor
  • there is not much air renewal
  • your brand new furnitures contains a lot of formaldehyde
  • your child is playing with the dog
  • air is quite still inside, so the dust tends to stay on the ground
  • there is no car in your living room, so no direct exhaust of pollutants

Your home


Do you see any other differences? Please give me your suggestions...

Indoors radicals like the element radon are emmited from concrete walls and accumlate indoors if there is no air exchange. Also the oxygen level goes down the more people are in the office (or house) and the less plants there are. Many people working in a Hongkong office are tired due to lack of oxygen. Most offices in sky scrapers are hermitcally sealed towards the outside with air conditioners but no "fresh air" exchange. At least Mainland Chinese like open windows (even in taxis in winter in Beijing). So if the outdoor polution goes down - then opening windows will help to reduce the indoor pollution. Untill then we have to use more air purifiers.
