Pesticide Recovery Studies for Evaluation of Department of the Army Pesticide Monitoring Program Soil and Sediment Analysis Methodology. Part I. Determination of Pesticide and Polychlorinated Biphenyl Recoveries from Soil Extracted Immediately Following Fortification.

摘要

This is a report providing analytical details and analytical results of pesticide and polychlorinated biphenyl (PCB) recovery studies used to evaluate Department of the Army (DA) Pesticide monitoring Program soil analysis methodology. The present study was specifically involved with the determination of pesticide and PCB recoveries from soil which was extracted immediately following fortification and then carried through routine soil transfer, cleanup, concentration and analysis procedures. The percent recovery values for eight of the nine pesticides studied and for Aroclor 1260 were essentially quantitative, ranging from 90.0 to 107.6. The recovery data clearly indicated that pesticide losses following immediate extraction of fortified soil samples, and during subsequent transfer, cleanup, concentration and analysis steps were minimal or nonsignificant using routine DA Pesticide Monitoring Program soil analysis methodology.
