Air Toxic Studies
- MATES V - The Multiple Air Toxics Exposure Study (MATES V) is being planned for 2018. Additional information is available on this webpage.
- MATES IV - Multiple Air Toxics Exposure Study (MATES IV) was conducted in 2012-2013. The final MATES IV report is available.
- MATES III
As part of the 2003-04 Environmental Justice Workplan (PDF, 52kb), the AQMD conducted a Multiple Air Toxics Exposure Study beginning in 2004. A Technical Advisory Group was formed and met periodically to provide technical review and input to staff during this study. These meetings were open to the public. Results are available in the MATES III Final Report.
- MATES II
At its October 10, 1997 meeting, the SCAQMD Governing Board directed staff to conduct a major air toxic evaluation program, referred to as MATES II (Multiple Air Toxics Exposure Study) to quantify the current magnitude of population exposure risk from existing sources of selected air toxic contaminants. This program was more comprehensive than a similar study conducted over a decade ago in MATES I, in that more sites were sampled, more toxic compounds were analyzed, and other elements such as microscale modeling were also incorporated into the study. The AQMD conducted this study in three parts addressing; (1) Air Toxic Monitoring; (2) Air Toxic Emissions Inventory Enhancements; and (3) Air Toxic Modeling and Risk Assessment. Further information is found in the MATES II Final Report.
- MATES I
The first Multiple Air Toxics Exposure Study was conducted in 1986-87 and the findings published in June 1987. This document is not available online, but a reference copy may be consulted in the AQMD's Library.
