Baraud et al. [41] developed a multiresidue method for the
determination of 16 polar pesticides in atmosphere, belonging
to 9 chemical families, using HPLC-UV. After extraction with
Soxhlet using n-hexane:diethyl ether (90:10, v/v) for 24 h, and
evaporation, the deposit was dissolved in 2 ml of mobile phase
(acetonitrile:water:acetic acid, 30:59:2, v/v). The limits of detection
ranged from 0.7 to 13.8 ngm−3.
