Total Risk Integrated Methodology (TRIM) Air Pollutants Exposure Model Documentation (TRIM.Expo/APEX, Version 4). Volume 2: Technical Support Document.

摘要

The documentation of the APEX model is currently divided into two volumes. Volume II: Technical Support Guide (this document) is intended to be a reference on the scientific basis of the APEX model. The scientific background, original references, and equations for the APEX model algorithms are included in this volume. Topics covered include the methods implemented in APEX for sampling probability distributions, calculating microenvironmental concentrations, modeling ventilation, estimating exposure and dose, and assembling composite activity diaries. Other model algorithms, such as those for generating the study area and the simulated population are also described.
