Atmospheric corrosion in the south east region of Gulf of Mexico can be intense and affect to a great extent the coastal economy, as the industrial installations and equipments are attacked sinergistically by natural and anthropogenic atmospheric pollutants. The corrosivity of atmospheres in this region is being studied and characterized by means of the ISO 9223: 1992 standard methodology. This study presents the preliminary results obtained at five different sites in the Gulf. Iron, copper, zinc and aluminium plates are exposed in metallic panels and the deposition rates of chlorides and sulfur dioxide, and the time of wetness are being monitored. After 12 months of exposure, the atmosphere has been classified as mildly aggressive with respect to those metals in one of the sites (Campeche). For the rest of the sites, an estimation of the atmosphere’s corrosivity is evaluated.
