We examined measurement methods of Dechlorane Plus (DP) for HRMS-EI and LRMS-NCI in this report. Both linearity of the calibration curves were excellent. IDL towards the LRMS-NCI and air samples towards the HRMS-EI were sensitive, respectively. The results of DP analysis for ambient air, syn-DP: 0.46-7.7 pg/m3, anti-DP: 1.5-16 pg/m3 and Total DP: 2.0-24 pg/m3 were detected, by two of the measurement method. The difference of the measured values had within permissible range. Surrogate recoveries obtained ranged from 90 to 120%. DP concentrations detected in this study was not a particular high value when compared to the concentrations of such POPs that have been literature reports. However, there were detected at a higher concentration than brominated flame retardants.
