The rate of removal and the compositional changes of diesel in Antarctic marine sediment
Diesels and lubricants used at research stations can persist in terrestrial and marine sediments for decades, but knowledge of their effects on the surrounding environments is limited. In a 5 year in situ investigation, marine sediment spiked with Special Antarctic Blend (SAB) diesel was placed on t...

Diesels and lubricants used at research stations can persist in terrestrial and marine sediments for decades, but knowledge of their effects on the surrounding environments is limited. In a 5 year in situ investigation, marine sediment spiked with Special Antarctic Blend (SAB) diesel was placed on the seabed of O'Brien Bay near Casey Station, Antarctica and sampled after 5, 56, 65, 104 and 260 weeks. The rates and possible mechanisms of removal of the diesel from the marine sediments are presented here.The hydrocarbons within the spiked sediment were removed at an overall rate of 4.7 mg total petroleum hydrocarbons kg−1 sediment week−1, or 245 mg kg−1 year−1, although seasonal variation was evident. The concentration of total petroleum hydrocarbons fell markedly from 2020340 mg kg−1 to 800190 mg kg−1,but after 5 years the spiked sediment was still contaminated relative to natural organic matter (160 170 mg kg−1).
