This study, the first to investigate workplace contamination in areas in Ghana where e-waste recycling and disposal is carried out, focussed on the main centre for this type of work, at the Agbogbloshie scrap market in Ghana’s capital, Accra. One of the numerous similar, though far smaller, operations that take place throughout Ghana was also investigated, at the location of a scrap dealer in Korforidua, a smaller city to the north of Accra.

Much of the work is carried out by children, commonly. | UNITED STATES ENVIRONMENTAL PROTECTION AGENCY REGION 9 Quality Assurance Office 75 Hawthorne Street San Francisco CA 94105-3901 USEPA REGION 9 TECHNICAL GUIDELINES FOR ACCURATELY DETERMINING VOLATILE ORGANIC COMPOUND VOC CONCENTRATIONS IN SOIL AND SOLID MATRICES R9QA 05.2 FINAL December 2005 EPA Region 9 Technical Guidelines for Accurately Determining Volatile Organic Compound Concentration in Soil and Solid Matrices FOREWORD The U.S. Environmental Protection Agency EPA is authorized to make decisions affecting public health and the environment. With the knowledge that there is an inviolable trust in the Agency EPA mandated that environmental data collected by and for the Agency be of known quality and as appropriate legally defensible in relation to the decisions to be made based on them.

These guidelines have been developed by the RQAM QA Office to support the mission of EPA Region 9. These guidelines update and replace the EPA Region 9 Regional Interim Policy for Determination of Volatile Organic Compound VOC Concentrations in Soil and Solid Matrices June 23 1999. If you have any questions please contact the Region 9 QA Office. December 2005 - 2 - EPA Region 9 Technical Guidelines for Accurately Determining Volatile Organic Compound Concentration in Soil and Solid Matrices ACKNOWLEDGEMENTS EPA Region 9 would like to thank all the technical reviewers
