Every year in January to return to the fore the pollution of the cities and return to talk about breaking the limits provided by law, anti-smog measures , units, etc.. I always wondered why this subject during the rest of steps a bit 'fashion and I have recently started to give me answers. The first thing to consider, from what I understand, is that there are various types of pollutants. Against some have already done a lot, such as carbon monoxide, which was the bete noire a decade ago and now seems to be quite a problem marginal, while others have not yet found the solution as fine particles, down from PM10, which are the focus of attention in recent years.
As mayor continues to repeat my (very little inclined to discourage car use), vehicular traffic accounts for only third on the production of fine particles. The other two thirds are said to be attributable to industrial activities and heating. Renzi cites to prove this, the day Saturday, December 18 (after the big snowfall and this with almost no traffic) when the control units recorded breaching the limits should note the massive use of heating. But even
polluting gas boilers? It seems so obviously a lot less than diesel. From what I understand, any burning of any produce pollutants. The heating factor explains why the summer, when even the air is very heavy, not so much talk of pollution.
A fellow researcher, who studies the particulate air pollution, he said they have found strong production at pellet stoves and fireplaces also. But how, our home that is both romantic atmosphere? This is also confirmed Dr. Tomasi, Department of Prevention of USL di Lucca, which, Controradio interviewed, said that unfortunately must dispel this myth that burning wood is eco-friendly, "just think that burning a kilogram of wood is like a car with 217 km Petrol Euro 0.
And then we turn off the chimney? Maybe turn down the thermostat while heating (the city ordinance in Florence do not plan to exceed 18 degrees, which is not much, but it is certainly more than bearable) and, if possible, should try to eliminate the dispersion measures with insulation houses. Public buildings, however, should lead by example. My children have always complained about how hot are the various schools who attended, for example. In the episode of Italy's Environment 02/05/2011 an experiment was done by hand and the thermometer are 25 degrees were also detected in a public office in Milan, not to mention the shame of shops with the door open (as was shown by 4 degrees measured outside the 22 steps is measured in a perfume just entered). Other than fireplaces!
