Vehicle Microenvironment Project

Please visit the VM Summary Page for a complete listing of the aims, investigators, and materials associated with the Vehicle Microenvironment (VM) hosted project.

The motor vehicle is a special kind of indoor environment, which requires special attention. Firstly, vehicles have much smaller volumes than most other indoor environments, and, therefore, pollutants emitted in their interior have the potential to reach peak levels that far exceed anything that would occur in homes, offices, and other indoor locations.

Air Change Rates of Motor Vehicles and In-Vehicle Pollutant Concentrations from Secondhand Smoke

Document Type: 

Journal Article

Description: 

This article describes a series of tracer gas experiments designed to measure vehicle air exchange rates for a variety of speeds, window positions, and ventilator functions. Experiments were also conducted to measure real-time particles from secondhand smoke in cars across various conditions.

Indoor Air Quality Project

Please visit the IAQ Summary Page for a list of the aims, investigators, and materials associated with the Indoor Air Quality (IAQ) hosted project.

The IAQ project hosted here investigates a wide variety of factors that impact the concentrations of air pollution that can occur in typical indoor environments. These factors include building construction, mass emission rates of different sources, ventilation rates, particle deposition rates, chemical reaction rates (including surface interaction), and indoor-outdoor particle penetration rates.
