Also discussed here: Half of Inhaled Soot Particles from Diesel Exhaust, Fires Gets Stuck in the Lungs (ScienceDaily. Jun. 27, 2012)
According to the research reviewed today, soot particles from diesel engines present a greater heath hazard because there more small particles from this source are absorbed into the lungs, compared to emissions from wood stoves and coal-driven power stations. In addition, soot particles impact on climate change and
reduction must accompany action to reduce greenhouse gases.

Key Quotes:
“Diesel emissions are a major contributor to combustion-generated airborne ambient particles”
“for the first time, researchers have studied in detail how diesel soot gets stuck in the lungs….more than half of all inhaled soot particles remain in the body” “"only" 20 per cent of another type of particle from wood smoke and other biomass combustion gets stuck in the lungs”
"Findings of this kind can be extremely useful both for researchers to determine what doses of soot we get into our lungs out of the amount we are exposed to, and to enable public authorities to establish well-founded limits for soot particles in outdoor air"
"Soot particles are black and absorbs light, thus producing a warming effect. So it could be a double advantage to reduce it" “The EU will be tightening rules on emissions for heavy duty diesel vehicles in 2014”
