| Title | Fingerprinting hydrocarbons in a contaminated soil from an Italian natural reserve and assessment of the performance of a low-impact bioremediation approach |
| Abstract | An environmentally friendly procedure
suitable to restore a protected area was evaluated at
laboratory scale. Soil contaminated by high molecular
weight (C>10) aliphatic hydrocarbons and by chromium
was withdrawn from the study site and a qualitative
study of soil hydrocarbon components was first performed
in order to assess the potential source of
contamination. To this aim, a number of characteristic
diagnostic ratios of hydrocarbon components were
derived by processing chromatographic data, and were
used as indicators for distinguishing anthropogenic from
natural hydrocarbons. Then, the efficiency of landfarming
for soil remediation was tested by comparing
the effect of a few selected amendments and by monitoring the fate of chromium. Soil microbial
abundance and activity were also evaluated. Results
showed that soil hydrocarbons were mainly of anthropogenic
origin and land treatment allowed effective
degradation by native microbial populations even in the
absence of amendments. The investigated procedures
had no effect on the mobilisation of chromium that
remained in its stable form of Cr(III). Conventional land
treatment may therefore be an effective and safe
procedure for the removal of hydrocarbons even in the
presence of chromium, and may be applied to areas
where low-impact procedures are strictly required. |
