Abstract Measurements with low pressure impactors show that automotive traffic produces larger amounts of nucleation mode material in the size range below 0,1 μm. Most of this material is soot and other organic carbon compounds. After aging, i.e. coagulation and dilution in the urban atmosphere, the nucleation mode material contributes to the accumulation mode and an accumulation mode of carbon is found at 0,5 μm. The size distributions of sulfur indicate that the sulfur compounds measured in… CONTINUE READING
