Environmental analysis of polar and non-polar Polycyclic Aromatic Compounds in airborne particulate matter, settled dust and soot: Part I: Sampling and sample preparation

Interests in Polycyclic Aromatic Hydrocarbons (PAHs) and their derivatives (Nitrated PAHs, Oxygenated Azaarenes Sulfur Heterocycles) have been growing because of toxicity. The first part this review gathers information on sampling Compounds (PACs) airborne particulate matter (PM), dust soot, extraction thanks to solvent methods, sample clean-up for further analysis. Atmospheric PM is generally sampled quartz-fiber filters. For settled as well PM, active samplers are used most cases. After sampling, solid/liquid necessary. At step, yields can be enhanced depending the device used, but also with optimization volume time. Most up-to-date devices Pressurized Liquid Extraction (PLE), Ultrasound Assisted (UAE) Microwave (MAE). extraction, purification (generally by SPE) concentration advised.
