Análisis y distribución de hidrocarburos policíclicos aromáticos (PAH's) en suelos y aguas de escombreras en Puertollano (Ciudad Real)

The aim of this study was to examine if the soils and waters of Puertollano area are affected by pollution of polycyclic aromatic hydrocarbons (PAHs) and their quantification. The results show that PAHs concentrations are higher in all samples than the reference levels gathered in the Spanish legislation. The possible actions for the coal waste remediation (re-wash of waste dumps, photodegradation and biorremediation) seems to be unviable in this case because of the large volume of materials affected, the slowness of these processes, and the geomorphological characteristics of the carboniferous Puertollano basin. During the spatial regional planning, maps showing the concentration of PAHs should be made to adapt the soil for its corresponding use. It is proposed to consider as contaminants more PAHs, such as naftalene or fluorantene in waters, and phenanthrene and benzo[ghi] perilene in soils
