We evaluated the new on site soil conditions and their potential risks immediately after a fire that completely destroyed the Brazilian Antarctic Station, on February 2012. The investigated variables were the concentration of potentially toxic elements (Cd, Cr, Cu, Mn, Ni, Pb, V and Zn) in soil samples collected close to the station and inside the burnt station's ruins. Soil samples collected 4years before the fire were used as reference samples for comparative purposes. Principal Component Analysis (PCA) and μ-X-Ray Fluorescence were used as preliminary tools to provide fast and reliable qualitative information about soil pollution. Inductively Coupled Plasma Optical Emission Spectrometry (ICP OES) was chosen for the quantitative determination of the chemical elements under study. A Toxicity Characteristic Leaching Procedure was applied to access the potential mobility of the chemical elements in the environment. We found high pseudototal concentrations of Cu, Pb and Zn in soils collected within the station's ruins reaching the alarming levels of 34,000±4,000, 13,700±500 and 42,200±1,700mgkg−1, respectively. A point that deserves a close and special attention is the possible contamination of nearby lakes that supply the station with water, due to the high leachable Pb and Zn concentrations of the contaminated soil. Also, attention should be given to the possible development of melting channels carrying contaminated water to the coastal marine ecosystem. Due to its high risk of contamination, a complete clean-up procedure ought to be carried out, with barriers to avoid leaching/washing, removal of all debris and underlying soil, and careful disposal of the contaminated material, followed by remediation.
