Subject Top Page: 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.

CADAMP Quality Assurance Project Plan (QAPP) 2005 Monitoring Protocol	Detailed programmatic information regarding the program management, sampling protocol, analytical methods, and quality control procedures are contained in these documents.

Sampler Standard Operating Procedures (SOP) Field Operations for CADAMP Flow Audit Procedure	Sampler operation, CADAMP specific field procedures, and the flow audit procedure are linked here.

Network Monitoring Sites	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.

Sampling Schedule - 2002 Sampling Schedule - 2003 Sampling Schedule - 2004 Sampling Schedule - 2005 Sampling Schedule - 2006	Comprehensive schedule for sample and field blank collection, filter change, and start of new sampling moments.

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.
