so thirsty! I do 200 liters of Coca Cola
never really tried to drink 200 liters of Coca Cola, or 100 liters of coffee all at once, or 500 liters of wine per meal, or eat 100 kg. pasta?
You know, certain amounts can be harmful to health, even if Coca Cola, coffee, wine, pasta and of itself is not poisonous .
quantities, in these cases are important.
But for some there is no difference between a and one thousand. That someone is the Simpleton.
appeared in a recent post on his blog reports that a CNR research (based on data of 'WHO) "found no major differences between a gas chamber and the cities of Turin and Milan" .
In fact, the perfect similarity is relevant only to the Simpleton, because the research clearly says something different ( Environment and health in high risk areas)
Obviously the Simpleton refers to the dangerous conditions of pollution of these cities. One of the major pollutants in the air is in fact the carbon monoxide and its carbon monoxide was used once for the gas chambers.
So far, so the comparison holds, but the quantities as stated are important.
Carbon monoxide is dangerous because breathing air containing this gas has the production of carboxyhemoglobin in the blood. When the proportion of carboxyhemoglobin is high compared to hemoglobin, the blood is unable to perform what is its main function: the transport of oxygen to the tissues. The harmful effects of exposure to CO are therefore to be attributed to a lack of oxygen in the blood. An exposure to concentrations of the order of 2000 ppm (parts per million, equivalent to 2300 mg / cu.m) for 15 minutes is fatal. But even a prolonged exposure for several hours at concentrations of the order of 50-100 ppm (57-115 mg / cu m) causes dizziness, headache and general weakness but is not deadly. While prolonged exposure for several hours at concentrations of the order of 10-30 ppm (11-34 mg / cu m) causes lengthening of reaction time and difficulty in challenging physical activity.
In fact, the World Health Organization sets out the following guiding values \u200b\u200bnot to exceed 100 mg / cubic meter averaged over 15 min, 60 mg / cubic meter averaged over 30 min, 30 mg / cubic meter averaged over a hours, 10 mg / m³ averaged over 8 hours. is no fully satisfying the legal limits: 10 mg / m³ not to be exceeded on average over 8 hours - 40 mg / m³ averaged over an hour (maximum).
But in a city like Milan and Turin, the Carbon monoxide is generally below the limits of the law, around 1 mg / cubic meter, far indeed from those 2300 mg / cubic meter of lethal concentrations or even to 10-30 mg / mc that can cause health problems. referred to as a cup of coffee, not a tank. Incidentally, the 10 mg of carbon monoxide, which we will never find in a cubic meter of air (the legal limit), we could very well breathe smoke a cigarette.
For someone so mathematics is an opinion, or perhaps entirely remains questionable the truth of the facts.
again about the facts: the concentrations of almost all air pollutants have decreased significantly over the last decades.
E 'enough based on data from the institutions ARPA (Regional Environmental Protection Association). There is only a pollutant that does not seem to fall and ozone. How is ozone? a pollutant? But we're not doing anything to reduce the famous hole? but they told us that is so valuable because blocks ultraviolet rays? right, but at high altitude. At ground level, where we live, ozone is a pollutant, in fact, ozone concentrations of 0.1 ppm causes eye irritation, throat irritation and respiratory irritation and dry mouth. just a normal allergy symptoms.
But maybe not ...?
No, No. The ban CFCs! poisoners, destroyers of the environment ... and of 'ozone!
As for the information coming from the CNR, we will deal with soon, because the speech is interesting.
