Introducción:

In 2001 the U.S. Environmental Protection Agency (EPA) designed a national network for monitoring air toxics compounds present in ambient air. The objective of this monitoring is to generate ambient air data and to compile these data in an extensive air toxics data base. The use of actual field measurements to compare and reconcile with estimates from source dispersion
models will refine the model and ultimately allow a better overall estimate of population exposure. The ultimate goal of this and other parts of EPA=s Air Toxics Monitoring Strategy is to fully characterize air toxics impacts and to assess health risks.

The purpose of this technical assistance document (TAD) is to provide guidance to support EPA regional, state, and local agencies responsible for the implementation of this national network, so that consistent high quality data are obtained. The information presented is intended to make recommendations and provide guidelines for approaches to air toxics monitoring that are presently advocated by EPA for application to the National Ambient Air Toxics Trends and Assessment Program.
