Detecting some VOCs (PAH) in hospital and university in Ouargla city Algeria

Indoor and outdoor has volatiles organic compounds VOCs in the air ambient of hospital and university Ouargla city Algeria. These compounds have been examined by using diffusive Analyst I and Analyst II of 2014 and 2015 autumn. The Analyst I determined BTEXs (Benzene, Toluene, Ethyl-benzene, and Xylene isomers) by chromatography coupled with flame ionization (GC-FID) in internal and external air. The Total BTEXs ranged from 131.4 to 41.4μg/m3. The Analyst II detected polycyclic aromatic hydrocarbons PAHs have lows mass molecular (Naphthalene, methylnaphthalene, Fluorine, Phenanthrene, Fluoranthene and Pyrene) by gas chromatographic coupled with mass spectrometer (GC/MS) the totals PAHs varied between 8, 6–1, 8μg/m3 in interiors and 0, 8–0, 6μg/m3 exteriors. The ration indoor/outdoor exceeds the sources exact of VOCs.
