Pressurized liquid extraction of polycyclic aromatic hydrocarbons from silicone rubber passive samplers.

Highlights: [•] A method was optimized for extracting PAHs from silicone rubber passive samplers. [•] Pressurized liquid extraction (PLE) with gel permeation chromatography was used. [•] Selective PLE with Florisil removed silicone oligomers but not sufficiently. [•] Recoveries of spiked PAHs ranged from 81% to 102%, with a mean of 93%. [•] The method saves considerable solvent and time compared to conventional methods. [ABSTRACT FROM AUTHOR]
