In-Depth Information
After a 1 year experimental period, the retention efficiencies verified in column
C1 for the dissolved Cu and Pb were 70% and 40%, respectively, and above 90%
in the columns C2 and C3. This demonstrates the high longevity of filter media in
these experimental conditions. A direct link of reactive layers and a high retention
efficiency of dissolved heavy metals can be established. Moreover a strong
resistance to chemical desorption of previously retained heavy metals in those reactive
layers was also found.
The results obtained in this research project encourage the development of
innovative engineering solutions for retention of heavy metals in highway runoff,
and thus contributing for surface and groundwater protection.
