Abstract

The organic composition of an uncontrolled hazardous waste dump (Nervion River, N. Spain) which produced a strong contamination of the nearby aquifers has been studied by core sampling (10 m) and subsequent analysis of selected sections (gas chromatography (GC) and GC coupled to mass spectrometry (GC-MS) of the solvent extracts). In most samples, all chromatographically resolved peaks correspond to polycyclic aromatic hydrocarbons originating from coal tars and industrial naphthalene mixtures. In addition to these compounds, in some cases hydrocarbons from lubricating oils encompassing a high unresolved complex mixture, steranes and hopanes have been found. The present paper provides the description of the chemical composition of these wastes at a molecular level.
