Abstract
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.
