Air pollution: how to defend yourself


Of air pollution you can die. It happened in London in December 1952, when more than 4,000 people died from respiratory complications attributed to the thick fog that enveloped the city for five consecutive days. It wasn't just fog, it was smog, a word that not surprisingly derives from English words smoke is fog, smoke and fog.

Today similar levels of air pollution they still occur in large cities in the developing world, where the health of so many people continues to be in jeopardy. In countries that have experienced industrialization before, the air quality is a little better; but the objectives of optimal reduction of harmful emissions are still all to be achieved.

So the question is: what can we do to contain theair pollution and that of the air we breathe at home? And how can we protect ourselves? Below is a series of common sense tips and tricks that have two things in common: they are useful for our health and simple to put into practice.

Beware of ozone (O3). This gas is beneficial when it is in its place, in the ozonosphere to protect us from ultraviolet rays, but it becomes harmful in high concentrations near the ground. On a hot and sunny day, the maximum concentration of ozone in the ground is reached between 11 and 17. Better to avoid outdoor physical activities in this range. Also for airing the house, better in the morning or in the evening. Smoking promotes the formation of ozone. The same goes for office devices, especially the copier.

Ozone, we said, is useful when it is in the ozone layer. The problem is that it decreases (the known 'ozone hole’) Mainly due to the pollution caused by human activities. Paradoxically, this is how things are: man's polluting activities reduce ozone where it is useful, in the atmosphere, and increase it where it is harmful, on the ground. The enemies of the ozonosphere are above all chlorofluorocarbons (CFCs) contained in spray cans, limited in many countries but not in all, and volatile organic compounds (VOC) contained in paints, solvents, cleaning products etc ... CFC and VOC are absolutely to avoid.

Beware of smog. The air in cities is polluted by sulfur dioxide, nitrogen dioxide and carbon monoxide generated by car exhausts and heating systems. To these substances is added the particulate matter of fine dust. Walking or cycling in the busy streets is harmful to health, even doing sports harmful (go to the parks to run!).

If you challenge theair pollution cycling in traffic certainly helps to use an anti-smog mask, but only if it is a valid product. Paper dust masks are of little or no use. Indeed, wearing a mask can have counterproductive effects because the microparticulate passes the same and is breathed with more vigor.

If you plan to buy an anti-smog mask, do it seriously, making sure that it complies with the EN 149 2001 standard (which defines the construction rules for respirators for dust protection) and has a protection class of at least FFP2 (medium efficiency).

Pay attention to the quality of the air in the house. Let's talk about air pollution indoor and it is the other side of the problem. The environments at risk are the home but also the office. In the second case, it is mainly the fine dust produced by printers that is incriminated. If you can't ventilate often, and in the office you usually can't, the dust filters applicable to printing devices can help:

Clean Air filter for S laser printers

Clean Air filter for laser printers M

Clean Air filter for laser printers L

Talking aboutair pollution domestic, the basic rules are two: change the air often (at the right hours) and avoid polluting products in cleaning. An air ionizer for the home like this one you find online can be very useful:
