Breathing motor vehicle emissions is not good for health, reveals a study published in the journal Arteriosclerosis, Thrombosis and Vascular Biology.
The study, which has been carried out by group of researchers from different institutions, has revealed that inhaling of motor vehicle emissions brings change in high-density lipoprotein (HDL) cholesterol.
The change further contributes to clogged arteries. Lead author Dr. Jesus Araujo from the David Geffen School of Medicine was of the view that the inhalation of emissions also changes good HDL into bad HDL.
Not only this, it leads to inflammation and causes tissue damage, which further leads to hardening of arteries. "This is the first study showing that air pollutants promote the development of dysfunctional, pro-oxidative HDL cholesterol and the activation of an internal oxidation pathway", said Araujo.
In order to reach at the above given result, the study researchers carried out an experiment on mice. Mice were divided into three sub-groups; the first group was exposed to vehicle emissions for a period of two weeks.
After two weeks, filtered air was provided to them for a week. On the other hand, the second group was provided with two weeks of emissions and the third group was provided with fresh and clean air only.
