BREATHING IN CAR CABIN - COSA SI RESPIRA IN AUTO?

Our interest in the breathing air quality in the passenger compartment of the car (Car Indoor Air Quality) comes from the fact that the car is now our third residence on the work environment and the home. In it you spend at least 1-2 hours a day, there is smoke and activities take place to reconcile with the guidance.

 

The interior of the car is a closed and very small. If it is not well ventilated, within a few minutes is filled with various harmful substances (see graphics), such as carbon dioxide, carbon monoxide, sulfur dioxide, nitrogen oxides, sulfuric acid, benzene, and so on. In addition, the renewal of air is almost always (unless to be on high mountain roads) from polluted sources (air intakes of the cars are put on the front of the vehicle and are therefore particularly exposed to the exhaust gases of cars ahead of us and alongside us).

70% carbon dioxide

 

30% volatile substances and gases (sulfur dioxide, nitrogen oxides, sulfuric acid, benzene, chlorine-free, ionized calcium, hydrogen sulfide, sodium, iron, zinc, lead, manganese, chromium, vanadium, copper, benzopyrene, nickel, cadmium, titanium, molybdenum, bismuth, antimony, beryllium

To dispose completely benzene vapors of unleaded gas entering the passenger compartment during a refueling (lasting about 3 minutes), keep the fan on for a maximum aeration plant for at least 15 minutes.

* These percentages are for a refueling carried out with all the windows open.

 

From 1 July 2000, by law, all gas stations will be equipped with a vapor recovery of benzene, capable of reducing emissions by 90%. Currently 60% of petrol stations has already adjusted to the standard (the new pumps are recognized for the tubes of the guns a bit 'bigger and a warning light that says "Vapor Recovery").

30% monossido di carbonio

30% sostanze volatili e gassose (anidride solforosa, ossidi di azoto, acido solforico, benzene, cloro libero, calcio ionizzato, acido solfidrico, sodio, ferro, zinco, piombo, manganese, cromo, vanadio, rame, benzopirene, nickel, cadmio, titanio, molibdeno, bismuto, antimonio, berillio)

Per smaltire completamente i vapori di benzene della benzina verde che entrano nell’abitacolo durante un rifornimento (della durata di circa 3 minuti), bisogna tenere accesa al massimo la ventola dell’impianto di areazione per almeno 15 minuti.

80% benzene

10% anidride carbonica

10% sostanze volatili e gassose (anidride solforosa, ossidi di azoto, acido solforico, cloro libero, calcio ionizzato, acido solfidrico, sodio, ferro, zinco, piombo, manganese, cromo, vanadio, rame, benzopirene, nickel, cadmio, titanio, molibdeno, bismuto, antimonio, berillio)

* Queste percentuali si riferiscono a un rifornimento effettuato con tutti i finestrini aperti. 

Dal 1° luglio 2000, per legge, tutte le pompe di benzina saranno dotate di un sistema di recupero dei vapori di benzene, capace di ridurne del 90% le emissioni. Attualmente il 60% dei distributori di carburante si è già adeguato alla norma (le nuove pompe si riconoscono per i tubi delle pistole un po’ più grandi e per una spia luminosa con la scritta “Vapor Recovery”).
