Organic aerosols in urban and waste landfill of Algiers metropolitan area: occurrence and sources
Article Abstract:
The role of polycyclic aromatic hydrocarbons (PAHs) in the air pollution of Algiers, Algeria, is discussed in detail, including sources of the contaminants and concentrations in relation to temperature and dispersion. Sources include a municipal landfill at Oued Smar and a sharp increase in automobile usage in the city. The authors chart the analytic procedure for sample testing, and graph the concentrations of particulate organic matter.

Carbonyl sulfide derived from catalytic oxidation of carbon disulfide over atmospheric particles
Article Abstract:
The effect of atmospheric particles on carbon disulfide is simulated with a reactor, and measured with FT-IR, mass spectrometry. With particle oxidation, the carbon disulfide is found to form carbonyl sulfide and elemental sulfur.

Behavior of hexavalent chromium in a polluted groundwater: Redox processes and immobilization in soils
Article Abstract:
Groundwater and soil analyses of an industrial waste landfill indicate that a slag heap, consisting mainly of mill tailings, is the main source of chromium. Downstream movement of hexavalent chromium (Cr(IV)) is limited by a redox mechanism involving chromate ions and ferrous ions in the groundwater. The transport and reduction of hexavalent chromium in the soils of the landfill are described.
