High Explosive Reclamation

Reference soil was collected in a reference site in Elorence (Italy). Real soil samples were collected in the Associated National Chemical Companies (ACNA) site (Cengio, SV, Italy). ACNA is a closed organic chemical industrial factory active since 1882 with the production of explosives (nitroglycerin, dynamite, and trinitrotoluene), paints, nitric and sulphuric acids, phenols, and amines, with serious levels of contamination of soil and surface waters, where a remediation and bonification plan started in 1999. The serious enviromnental contamination of this area determined its inclusion in the list of national priorities for enviromnental reclamation. The sampling was performed from the soil layers (0-30 cm) in a specific ACNA site, called hill n°5, on March 2003. The hill was made of waste from the industry accumulated during the years and was divided into four zones zone 1 with low contamination level zone 2 with pseudoreference zone 3 with moderate pollution level, and zone 4 with high ecological risk.
