Edit: As for the black smoke diesels blow out, its soot and it settles on the ground. It's the crap that the gasolines put into the air that I'd be more concerned with.
"But when it comes to smog-forming pollutants and toxic particulate matter, also known as soot, today's diesels are still a lot dirtier than the average gasoline car."
"There are three size categories of soot particles:
* Large soot particles (>10 microns) deposit from the air into your nose, throat, and lungs, causing coughing and irritating your throat, and are ejected from your body through sneezing, coughing, and nose blowing.
* Coarse soot particles (~10 microns) are inhaled into your windpipe and settle there, causing more irritation and more coughing.
* Fine and ultra-fine soot particles (less than 2.5 microns) are the most successful at invading your body—they're small enough to travel deep into your lungs. Once there, these soot particles can irritate and mutate the most sensitive tissues in your lungs, your alveoli. These air sacs exchange oxygen and carbon dioxide from the air you breathe with blood in your capillaries, thus allowing your circulatory system to carry oxygen to the rest of your body. Soot particles, however, make this task more difficult because they cause inflammation and scarring of the alveoli. This also strains your heart because it must work harder to compensate for oxygen loss.
Soot also finds other ways to harm your body, including:
* chronic bronchitis,
* asthma,
* reduced ability of respiratory system to fight infections and remove foreign particles, and
* cancer.
All this means that diesel pollution can be deadly, causing premature mortality through cancer or heart and respiratory illnesses. The California Air Resources Board has concluded that diesel soot is responsible for 70% of the state's risk of cancer from airborne toxics. In the population as a whole, studies have shown a 26% increase in mortality in people living in soot-polluted cities."
I took that from this Site.
So it really isn't just soot, it causes a lot of problems...
There is a BIG reason why California is FINALLY cracking down on diesels. Either way, we need cleaner running cars and trucks... but diesels have no restrictions at the moment... so Jack A$$es can blow all the soot they want and get away with it.
Both diesel and petrol cars pollute and neither is better than the other..
