So I mentioned my belief that car exhaust is comparable to smoking to one friend who finds cars very convenient. So to help back up my case here's some references.

But to start off "UCLA researches studying somgs' health effects found that non-smokers living in smoggy glendora, california scored the same on certain respiratory health tests as chronic smokers from cleaner Lancaster." (Divorce your car!,, by Katie Alvord, pg 75



Of these, the major sources of toxic VOCs in both New Jersey and California appear to be aromatic sources resembling automobile exhaust, gasoline vapor, or environmental tobacco smoke for personal exposures and automobile exhaust or gasoline vapors for outdoor concentrations.

Note the relatively equal treatment of the sources of polution.

Although this research is from India, it's still interesting.
Alarmingly, 94 to 96 per cent of the children were found producing sputum, which would usually be reflective of the children being habitual smokers. But only 5.5 per cent of the children were found to be smokers and that too occasional. The culprit in this case, researchers concluded, was the pollution in the ambient air.

From the physicians for social responsibility.

Smokers typically have COHb levels of 5-6%. Setting aside tobacco and indoor sources, the relationship between ambient CO concentrations and blood levels is largely determined by duration of exposure and ventilation rate; the latter is roughly correlated with workload. Older US National Health and Nutrition Examination Survey
biological monitoring data shows mean wintertime carboxyhemoglobin (COHb) {in the general population}to be about 1.2%, with 3-4% of population above 2%. For example, during heavy labor in a busy traffic tunnel with CO levels of 42 ppm, the COHb would reach about 5% in 90 minutes. Risk groups include commuters, smokers, persons working in traffic. Persons with cardiac and pulmonary disease are most vulnerable; symptoms such as dyspnea and angina may develop at COHb levels of 3-4%.


From the CDC on Acrolein
There is very little information about how exposure to acrolein affects people's health. The information we have indicates that breathing large amounts damages the lungs and could cause death. Breathing lower amounts may cause eye watering and burning of the nose and throat and a decreased breathing rate.

How might I be exposed to acetone?.Smoking tobacco or breathing air containing tobacco smoke or automobile exhaust
