Broward County Air Toxics Monitoring Program
In 1992 Broward County developed its Air Toxics program. The goals of this program were to identify the major environmental and health concerns in Broward County, develop recommendations and strategies to regulate hazardous air pollutants, and to involve County communities in reduction of toxic air pollutants.
Broward County Air Toxics Monitoring Network
The Broward County air toxics monitoring network consists of two permanent sites that collect data on a long-term basis (sites number: 8 and 30). These sites are equipped with programmable/automatic systems to guarantee sampling quality. Four meteorological stations provide information for modeling and data analysis.

Broward County Air Toxics Sample Collection
Sampling equipment consists of Summa canisters with high purity, mechanical mass flow controllers, and timers attached to the canister valve ports.
Air toxics (also known as hazardous air pollutants or HAPs) samples are collected every sixth day, following the National Urban Air Toxics Monitoring Program (UATMP) schedule. Samples are collected for 24-hours (from midnight to midnight) on the sampling day.
Broward County Air Toxics Sample Analysis
Analysis of the air toxics samples is performed by the Broward County Environmental Monitoring Laboratory. Currently twenty-seven HAPs targeted by the U.S. EPA’s National-Scale Air Toxics Assessment are analyzed for using U.S. EPA Method TO-15 (pdf - 889Kb). These compounds include acrylonitrile, benzene, 1,3-butadiene, chloroform, 1,3-dichloropropene, methylene chloride, tetrachloroethylene, 1,1,2,2-tetrachloroethane, and vinyl chloride. The lab uses an Agilent 5973 Network Mass Selective Detector which combines GC/MS performance with instrument control, data communication, and analytical capabilities to perform HAPs analysis.
