After completion of this course, learners will be able to explain the key aspects of ambient air toxics monitoring.

The course is comprised of 7 modules:

Module 1: What are Air Toxics?
After completion of this module, learners will be able to define air toxics. Specifically, learners will be able to:

Explain the term air toxics.
Explain the characteristics of air toxics.
Explain what the hazardous air pollutants (HAPs) list is under the Clean Air Act.
Explain how the HAPs list is revised under the Clean Air Act.
Module 2: What are the Sources of Air Toxics?

After completion of this module, learners will be able to list the sources of ambient air toxics.

Module 3: Ambient Air Toxics Monitoring: How is it Different from Ambient Criteria Pollutant Monitoring?
After completion of this module, learners will be able to explain the key programmatic difference between ambient air toxics monitoring and ambient criteria pollutant monitoring.

Module 4: Why Monitor Ambient Air Toxics?
After completion of this module, learners will be able to explain the objectives of monitoring air toxics.

Module 5: Basic Considerations for Development of an Ambient Air Monitoring Network
After completion of this module, learners will be able to explain the basic considerations for developing an ambient air monitoring network of sites for a criteria pollutant or hazardous air pollutant, consistent with monitoring objectives.

Module 6: The EPA’s Ambient Air Toxics Monitoring Program
After completion of this module, learners will be able to describe each of the key activities of the Environmental Protection Agency (EPA)'s ambient air toxics monitoring program. Specifically, learners will be able to:

Describe key monitoring networks for collecting air toxics data.
Describe targeted air toxics studies.
Explain the purpose of measurement methods development.
Describe quality assurance.
Module 7: Measurement of Air Toxics at the National Air Toxics Trends Stations (NATTS) Network

After completion of this module, learners will be able to explain measurement of different air toxics compounds at the NATTS Network. Specifically, learners will be able to:

Explain classification of air toxics for measurement.
Identify the four analyte classes for measurement.
Explain how ambient air toxics are sampled and analyzed.
Explain methods used for measurement of air toxics.
