Inhalation Exposure Simulation Modeling

Aims: 

This project seeks to develop, apply, and evaluate models of human exposure to air pollution in homes, cars, outdoors, public locations, offices, etc. These models make use of human activity pattern data, material balance models, monitoring data, and environmental parameters to predict exposures and explore their determinants for both individuals and populations. A main goal is to identify ways to reduce or eliminate hazardous exposures from our everyday lives.

Modeling Residential Exposure to Secondhand Tobacco Smoke

Document Type: 

Journal Article

Description: 

Article presenting a simulation study of the impact that the multicompartment nature of US homes has on residential exposure to secondhand tobacco smoke. Both hypothetical scripted behavior and observed distributions of human time-location patterns in US homes were used as input to the simulation model.
