All to count the descent of harmful gases or greenhouse, for the due to stationary vehicles during the epidemic. The first findings say that many oxides drop, but the particulate matter, not too much. The variety and quantity of particulate matter is dependent on the other that from the engines of the cars turned on. The cue is also useful to talk about how are the tires and the brakes, to generate and stir up the particulate matter in the air. An air-influenced then from other sources, industrial or heating, and not least from the weather. Remaining in the world of car however, a recent study (Emissions Analytics), speaks of the pollution during the whole life-cycle of a vehicle. Well, the emissions of particles from a part of the group NEE (non-emission at the exhaust of the motor) is higher than that normally imposed on the motor.
Translated, according to the study, today is not the exhaust pipe that emits more particulates, in a car. Conditions worse, for this aspect, are the tyres and road surfaces maltenuti, drive heavy (such as certain electrical wear of the material brake. The estimation of the English says that the part of the emissions of the exhaust of the car is higher and far, both for PM2,5 to PM10. If you listen to these recommendations in the near future we will see the class issues (not those EuroX engine) for the cars… That before the ignorant called zero emissions (absolute, without specifying at the exhaust): electrical services. Of course, this is a stimulus, purposeful.
