Question
Air pollution due to the indoor air is always considered more compared to outdoor because:
- Air circulation indoors is very much lower
- Air circulation indoors is very much higher
- More fossils fuels are burnt inside the house
- Air circulation is moderate inside the house
Hint:
The pollutants inside the home remains inside due to less space and no air.
The correct answer is: Air circulation indoors is very much lower
Air pollution due to indoor air is always considered more compared to outdoor because Air circulation indoors is very much lower.
Indoor pollutants are more concentrated than outdoors. Simply because there is less space and air inside the house than outside. And that's why pollutants are more densely packed. Every time you take a breath, you breathe in more pollutants than outside your home.
Winds are stronger outdoors than indoors, which can blow away outdoor pollutants. Showers can also reduce pollution. However, this is not the case indoors.
