Abstract
The scope of the work is to correlate the ecological impact of a phenanthrenepolluted
soil to the matrix characteristics and the contamination ageing. Clean
sand, clay and loamy soils have been contaminated with phenanthrene.
Furthermore, sandy soil has been peat amended as a mean to detect the role of
organic fraction as a contaminant absorber. Samples were exposed to weather for
up to 6 months in controlled conditions. At regular time intervals, chemical and
ecotoxicological assays have been carried out in order to determine the effect of
natural ageing and biodegradation phenomena (decrease in total contaminant
amount and leachable fraction in solvents with different polarity). Parallel to
chemical analysis and toxicological tests, a biological assessment has also been
acco
