Research Links for Ventilation and Secondhand Smoke

A soundbite...

“1/2 to 7 air changes per hour is the practical range of ventilation in most buildings. The [research] illustrates that under all conditions of typical smoking and ventilation, the annual average level of the U.S. National Ambient Air Quality Standard (NAAQS) for fine particles (PM2.5), which defines clean air, is violated.
The NAAQS is designed to protect against air-pollution induced morbidity and mortality.”

talking points...

Under Section 112 of the federal Clean Air Act, pollutants may be designated as “hazardous air pollutants” (HAPS) if they can cause serious morbidity or mortality, as ETS does.

ETS actually contains 5 HAPS pollutants, more than 100 poisonous chemicals, and 47 chemicals classified as hazardous waste under RCRA.

ETS emitted into the outdoor air from a smokestack industry would qualify for regulation as a HAP mixture, like coke-oven emissions.

While no official ETS indoor air quality (IAQ) standards have been adopted in the U.S., proposed ... standards ... are based on limiting ETS lung cancer and heart disease risk to de minimis levels.
Application of these putative standards to restaurants, bars, and casinos shows that tornado-like levels of ventilation would be required to control ETS.
Moreover, enforcement of an official ETS-ventilation standard would require establishment of costly new regulatory bureaucracies.
