Hazardous and Noxious Substances Spill Incidents

Advanced Search

On this database it is collected information on the fate and weathering of hazardous and noxious substances (HNS) accidentally spilt at the sea around the world. It gathers and systematizes existing information to assist stakeholders involved in spill preparedness and response, and builds return of experience datasheets for the chemicals involved. It will facilitate the incorporation of lessons from past incidents on the decision process to improve preparedness.

Fate and weathering facts observed/reported

The entire cargo of styrene, considered as a marine pollutant, toxic and relatively insoluble, was pumped out. However, IFREMER detected styrene in the gills and tissue of crabs in the vicinity of the wreck, since leakage was detected by a French Navy submersible drone. Initial visual surface observation showed a slick and styrene vapours were detected at a nearby Island (Alderney), both through odour and GC-MS samples, but never detected on French shoreline. Overtime, additional attempts were made to detect styrene by means of direct water sampling, however, this was ineffectual, probably due to high intensity currents that resulted in significant dilution, or spreading of styrene. The behaviour of the chemicals spilt in the prevailing conditions around the wreck was totally unknown. Experiments were quickly implemented.

HNS Classification (2010 HNS Convention)

Fate and weathering facts observed/reported

The methyl ethyl ketone, considered to have low toxicity impact and to be relatively soluble, not constituting a real hazard for the environment, underwent controlled release through holes drilled in the ship’s hull. The release of methyl ethyl ketone showed no evidence of environmental impact.

HNS Classification (2010 HNS Convention)

Fate and weathering facts observed/reported

The isopropyl alcohol, was deemed to have no toxic effects, to be highly soluble, and not constituting a real hazard for the environment. It underwent controlled release through holes drilled in the ship’s hull. The release of isopropyl alcohol showed no evidence of environmental impact.
