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

Phosphorite can contain heavy metals (lead, arsenic, cadmium, mercury and chrome). Two agents from CEDRE were sent on site 2-3 months later to determine whether the marine environment and the water for consumption from coastal wells were polluted due to the spill of fuel and cargo. Water samples (sea and wells) and fish samples were taken. Analysis carried out in CEDRE’s laboratory showed no pollution due to the ore carrier.
