California Ambient Dioxin Air Monitoring Program (CADAMP)

This page last reviewed January 7, 2009

The Air Resources Board (ARB) is collecting information about ambient levels of dioxins and dioxin-like compounds (furans, polychlorinated biphenyls and polybrominated diphenyl ethers) in highly populated urban areas. The ARB program includes two major components: 1) ambient monitoring for dioxins and dioxin-like compounds at multiple locations statewide; and 2) identification of potential dioxin-emitting sources. Due to questions that have been raised about the causes and sources of dioxins and dioxin-like compounds as well as the environmental fate and the potential for public health impacts from these highly toxic chemicals, a monitoring network has been put into operation. Information about the California Ambient Dioxin Air Monitoring Program (CADAMP) can be found below.

Program Overview

Background information about ARB's urban dioxin study and the EPA's national rural dioxin study. You may also access our presentation of this summary in Powerpoint or PDF.


Monitoring Results

Monthly dioxin, PCB and PBDE data for each site can be found here.

In 2005, data for 2002-2004 was presented at the Air and Waste Management Association (AWMA) conference held in San Francisco. You may view the presentation slides in
Powerpoint and the published article in PDF here.

Locations of the CADAMP sampling sites are shown here with information regarding why these particular sites were chosen and descriptions of current activities at each site.


Samplers, Media and
Analyte List

The sampler used in ARB's air monitoring program collects air on a quartz fiber filter and polyurathane foam. The sample collection device is shown here with the list of target compounds.

Analytical Methods

The methods used for sample analysis for the CADAMP are modifications of standard EPA methods 1668A and TO-9A. These reference methods can be found here.


Children's Environmental
Health Protection Program

Several of the CADAMP sites are also part of the Children's Environmental Health Protection Program (SB25). You will find information about that program as well as SB 25 monitoring results here.
