The third installment in our series of mass balance tutorials is on the three zone mass balance model. Using this tutorial, you can explore realistic 3-room residential layouts and potential exposures that may occur when a smoker is in an adjacent room.

I just added a new Flash-based tutorial on the two-zone mass balance model. This tutorial allows you to interactively explore the effect of different parameters on the transport of pollution generated in one room to an adjacent room. In the future, I will be adding more Flash-based tutorials, and I will create Flash simulations of secondhand smoke exposure aimed at different audiences.

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.
