Willison, S., Dan Stout, A. Mysz, J. Starr, D. Tabor, B. Wyrzykowska-Ceradini, J. Nardin, E. Morris, AND E. Snyder. Evaluation of Wipe Sampling Parameters and Surface Analysis of Misused Pesticides on Indoor Surfaces. Presented at Joint Meeting of SFIREG Working Committees for Pesticide, Arlington, VA, April 09 - 10, 2018.
Impact/Purpose:
Excessive application or off-label use of pesticides have resulted in inappropriate use for indoor environments. Surface wipe sampling and analysis techniques are relied upon to successfully evaluate contamination and facilitate remediation efforts. No consensus on sample collection for surfaces exists, and Federal, State and local agencies responding to an incident may use different procedures. Unless identical sampling materials and procedures are implemented in the field, the results are difficult to compare and interpret. This investigation focuses on understanding the impacts of specific variables associated with a wipe sampling procedure and how the variables affect target analyte recoveries. Different wipe sampling variables and techniques were evaluated so that those responding to pesticide misuse incidents can better assess method performance. ORD research will be presented at the Joint Meeting of SFIREG Working Committees for Pesticide Operations and Management and Environmental Quality Issues in order to provide information that may assist with surface recovery during remediation incidents.
