Biomarkers and low-molecular weight polyaromatic compounds have been extensively studied for their fate in the environment. They are used for oil spill source identification and monitoring of weathering and degradation processes. However, in some cas
Source identification of petroleum pollutants in the marine environment is a very difficult but important task for both environmentalists and governments and many markers are used to reach this goal. Among these are the polycyclic aromatic sulfur het
