SMOC: acid rain in Venezuela caused by refinery

Oil Refinery Smoke Over CuracaoWILLEMSTAD – An article published in 1998, showed that there was wet deposition (rain) in different places in Venezuela. SMOC retrieved the article, saying that this was due to human activity and was probably due to the refineries in Curacao and Aruba.

They found that the pH of Lake Maracaibo Basin was so low, that there should be anthropogenic causes for this. In other words, there must be a human activity that affects this. In this they should strongly consider that the cause of this is partly from the emissions of the refineries of Aruba and Curacao.

According to the SMOC, refineries emit sulfurous substances that are converted to acids. These acids come into contact with rain water, and that is the cause for the low pH of the rainwater.

The article can be found at SMOC ISBN 3051-3058 (Morales et al, Atmospheric deposition of SO4-S and (NH4 + NO3-)-N at two rural sites in the western Maracaibo Lake Basin).
