There's no escaping it: we too pollute our homes. And since we spend 90% of our time indoors, this is where we breathe in most of the pollutants. Contrary to what you might think, what emerges from an article in Focus magazine, indoor air is far from healthy and can be more polluted than outdoor air even in cities.
The reason is that in homes, offices, schools and gymnasiums, in addition to the dust and gases that enter from outside, through doors and windows, there are a myriad of other harmful molecules produced internally.
The European Commission's Scientific Committee on Environmental and Health Risks has counted 900 of them, dividing them by type, including those generated by combustion (of cigarettes, for example), volatile organic compounds (mentioned here) and allergens, linked to the presence of dust, mould and domestic animals.
