Chemical testing of water and sediment samples gathered two miles from the Elgin platform gas leak indicate there has been no direct marine contamination from the incident.
Samples collected were tested for the presence of oil and gas (hydrocarbon) pollution at the Marine Scotland Science laboratory in Aberdeen. Results are now available for seawater and sediment. The chemical analysis of fish, which sensory testing last week found to be untainted by hydrocarbons, is ongoing.
Some traces of oil-based hydrocarbons were found in seawater samples, however analysis has revealed that it is not directly linked to the gas leak and is instead likely to be caused by other shipping or industrial activities in the area. The sediment samples were found to be unaffected by the gas leak, with the samples’ chemical indicators being typical of what is found elsewhere in the North Sea.
Scottish Environment Secretary Richard Lochhead said: “I’m pleased that chemical analysis of water and sediment samples is now available, which adds to the sensory fish testing work completed last week. However, as the leak is ongoing, we must remain vigilant and I’ve asked Marine Scotland to continue to play a full part in assessing the situation, including further environmental monitoring.”
