Multi-Chamber Concentration And Exposure Model (MCCEM)Entry ID: EPA-MCCEM
Abstract: Multi- Chamber Concentration and Exposure Model (MCCEM)
.- Estimates average and peak indoor air concentrations of chemicals released
from products or materials in houses, apartments, townhouses, or other
residences. The data libraries contained in MCCEM are limited to residential
settings. However, the model can be used to assess other indoor environments
(e.g. schools, offices) if the user can ... supply the necessary inputs.
- Estimates inhalation exposures to these chemicals, calculated as single day
doses, chronic average daily doses, or lifetime average daily doses. (All dose
estimates are potential doses; they do not account for actual absorption into
How Does MCCEM Work?
- MCCEM is a user-friendly software product that estimates indoor air
concentrations using a mass balance approach.
- Maintains a library of residences, containing data on zone or area volumes,
interzonal air flows, and whole-house exchange rates.
- Allows you to tailor your analysis to a particular location, and to model air
concentrations in as many as four zones for a given residence.
- Estimates exposure for periods ranging from 1 hour to 1 year. Develops
seasonal or annual exposure profiles using a long-term model.
- Offers several different options for dealing with 'sinks'. A sink is a
material (e.g., carpeting, wallboard) that can absorb chemicals from the air;
the absorption can be either reversible or irreversible.
