Remediation of petroleum hydrocarbons in polar environments is more costly and logistically and technically more difficult than corresponding temperate and tropical contaminated sites. Bioremediation and in-situ chemical oxidation (ICO) are possible strategies which may overcome the financial and te...

Remediation of petroleum hydrocarbons in polar environments is more costly and logistically and technically more difficult than corresponding temperate and tropical contaminated sites. Bioremediation and in-situ chemical oxidation (ICO) are possible strategies which may overcome the financial and technical challenges associated with polar-region site remediation. ICO involves introducing reactive chemicals to contaminated soils so that organic contaminants such as petroleum hydrocarbons are oxidised to environmentally innocuous compounds, while bioremediation relies on microbial activity to achieve this. At Old Casey Station, East Antarctica (66°17'S, 110°32'E) more than 20 000 L of Special Antarctic Blend (SAB) diesel fuel was spilt over 15 years ago.
