The relationship between the particle size in automobile exhaust and also the incidence of eye irritation remains unclear; but, one man of science has indicated that below zero.2 microns, irritation is basically prevented. it’s believed that the creation and performance of the car verify the emission of hydrocarbons and chemical element oxide, but individual organic compound levels rely additional upon the kind of fuel used. each of these chemicals manufactures eye irritation equally.
