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.
The city of Belmont, California has passed a law banning smoking inside multi-unit housing. Soon, we at SimSmoke.Org will offer tools to explore exposures caused by leakage or drift of secondhand smoke between apartment or condominium units.
The founder of the SimSmoke.Org website is now contributing to a new website TobaccoSmoke.Org, which aims to disseminate scientific information on exposure to secondhand smoke to the public. The new website contains booklets and briefings on published exposure measurements in cars, homes, the outdoors, and other locations.
A new article has been published (July 2007) on the amount of secondhand smoke air pollution that can occur in automobiles under various conditions. The Stanford University researchers (Ott, Klepeis, and Switzer) also measured many air exchange rates for different types of automobiles, which are valuable for use in simulating in-vehicle exposures to secondhand smoke as we do on the SimSmoke.Org website.
The World Health Organization (WHO) have released their report Policy recommendations on protection from exposure to second-hand tobacco smoke. This document offers approaches to implementing policies that protect people from exposure to secondhand smoke. From the executive summary:
I have started created tutorials that make use of the Flash animation player. To start, the first tutorial is on the mass balance model. This model is one of the the basic building blocks for simulating indoor exposure to SHS.
This is the first interactive flash-based simulation at SimSmoke.Org. Please "play" with the car exposure simulation below, which features integrated instructions. When you are done using the simulation, please take a survey.
[Ed. note: The embedded flash does not seem to work with some versions of Internet Explorer. If you do not see an embedded flash animation below, please click on this link. You will need the Adobe Flash Player to see this simulation.]
