The complex composition of secondhand smoke (SHS) provides a range of constituents that
can be measured in environmental samples (air, dust and on surfaces) and therefore used …

Because human activities impact the timing, location, and degree of pollutant exposure, they
play a key role in explaining exposure variation. This fact has motivated the collection of …

Indirect exposure approaches offer a feasible and accurate method for estimating population
exposures to indoor pollutants, including environmental tobacco smoke (ETS). In an effort to …

The current lack of empirical data on outdoor tobacco smoke (OTS) levels impedes OTS
exposure and risk assessments. We sought to measure peak and time-averaged OTS …

Background: Residential natural gas cooking burners (NGCBs) can emit substantial
quantities of pollutants, and they are typically used without venting range hoods. Objective …

Because size is a major controlling factor for indoor airborne particle behavior, human
particle exposure assessments will benefit from improved knowledge of size-specific particle …

The amount of light scattered by airborne particles inside an aerosol photometer will vary not
only with the mass concentration, but also with particle properties such as size, shape, and …

Real-time particle monitors are essential for accurately estimating exposure to fine particles
indoors. However, many such monitors tend to be prohibitively expensive for some …

Indoor sources can greatly contribute to personal exposure to particulate matter less than
2.5 μm in diameter (PM2. 5). To accurately assess PM2. 5 mass emission factors and …

For modeling exposure close to an indoor air pollution source, an isotropic turbulent
diffusion coefficient is used to represent the average spread of emissions. However, its …
