Abstract
Phytotechnologies are all the applications that use plants to interact with contaminants located in
environmental media. A correct use of phytotecnologies is strictly linked to a deep knowledge of
plant – contaminant interaction mechanism. This study explores three different kinds of plant –
contaminant interaction. The first case study aimed to evaluate interaction between Phragmites
australis and a heavy metal polluted sediment (Zn, Cu). The study explored the possibility of use
Phragmites australis to control environmental risks of an artificial pond filled with the tested
sediement. In the second study the willow tree toxicity test was tested in two different conditions;
first condition aimed to optimize Zn bioavailability in water, in the second condition, a low zinc
bioavailability was tested.
The third study focused on heavy hydrocarbons interactions with populous and black locust grown
on the top of an old abandoned industrial landfill. The aim was to verify a relationship between
heavy hydrocarbons located in the substratum (soil and waste) and the heavy hydrocarbons
located in leaves and young branch of poplar and black locust. The analysis was addressed to
verify the possibility to use phytoscreening technology to describe a heavy hydrocarbons
contamination in soil.
