  1. aMDL and MQL are calculated by dividing the detection and quantification limits (LODs and LOQs) by the sampling volume.
  2. bmLOD and mLOQ were calculated based on the signal: noise ratio of 3 and 10, respectively, for the compounds quantified in real air samples and then dividing by the sampling volume.
