Comparison of polyurethane foam and XAD-2 sampling matrices to measure airborne organophosphorus pesticides and their oxygen analogs in an agricultural community

► XAD-2 matrices artificially transform OPs to oxygen analogs during air sampling. ► PUF matrices are the superior method for air sampling OP/oxygen analog mixtures. ► Higher levels of more potent oxygen analogs are detected in air post-application. ► Higher concentrations oxygen analogs are detected farther distance from the source. ► Larger % OP oxygen analogs are identified in vapors than deposited particulate.
