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 cargo, totally constituted of methanol, leaked into the environment without greater consequences due to its combustion by the fire that followed an explosion and by evaporation. The methanol being an inflammable compound, highly volatile and explosive, the product existing in the ship burnt, volatized or diluted in the seawater in the first hours, or in the first days, after the accident. Thus, no quantity of this product was recovered during the breakup of the ship. However, the fuel oil from the ship’s tanks also leaked into the environment, causing extensive environmental damage in Paranaguá bay. Most of pollution was described to be related to the fuel oil spilled simultaneously (IFO180), around 400 T.
