Smokers Emit More Pollution Than Cars

An article in the Orange County register presents a smoker who is also a smog technician. Compared to the emissions from the tailpipe of a car, the smoker is "a gross polluter." In fact, while cars only emit about 200 micrograms of fine particle mass per mile driven, a smoked cigarette emits about 10,000 micrograms. What does this mean for people riding inside a car with a smoker? You can explore this issue using the simulations available on this website.

California Bans Smoking in Cars with Minors Present

California governor Arnold Schwarzenegger signed a bill that bans smoking in cars when there are hildren 17 or under. Those caught doing so will face a $100 fine. The infraction will be a secondary offense, meaning that a police officer could not stop a motorist only for smoking in a car with a minor. Use the car exposure simulation to see how high secondhand smoke levels can be in cars.

Revised NAAQS for Fine Particles

The USEPA has announced the revision of their 24-h National Ambient Air Quality Standards (NAAQS). The 24-h standard for fine particulate matter was reduced from 65 to 35 micrograms per cubic meter (μg/m³).

This is an important development, because it indicates that the USEPA has reviewed many peer-reviewed studies, and they have found that harm can occur from exposures to fine particles that exceed the new, lower level.
