Particulate Matter."Particulate matter," also known as particle pollution or PM, is a complex
mixture of extremely small particles and liquid droplets. Particle pollution is made up of a number
of components, including acids (such as nitrates and sulfates), organic chemicals, metals, and soil
or dust particles. Once inhaled, these particles can affect the heart and lungs and cause serious
health effects. Includes PM2.5 (particles less than 2.5 microns in aerodynamic diameter), PM10
(particles less than 10 microns in aerodynamic diameter), and PMC (particles between 2.5 and 10
microns in aerodynamic diameter).
Parts per Million (ppm). This unit represents the concentration of the pollutant in a million parts
of air. Carbon monoxide is often measured in units of ppm.
Parts per Billion (ppb). This unit represents the concentration of the pollutant in a billion parts
of air. Ozone concentrations in BenMAP are reported in units of ppb.
Pooling.The combining of different sets of data. BenMAP has several pooling methods,
including fixed effects, fixed/random effects, and subjective weighting. Appendix K discusses
the pooling approaches available in BenMAP.
Point Mode.When defining the configuration, you may choose to either estimate adverse
health effects in point mode or using a Latin Hypercube. The point mode simply means that
BenMAP will use the mean value of the coefficient in the health impact function.
