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

Lindane container was never recovered. Fishing was banned in the area around the wreck. Water and fish samples were collected and analysed within a radius of 12 km around the presumed position of the lindane container, but none of them contained an abnormal quantity of lindane. Due to the low solubility of this substance in water, the chosen solution was to leave the container on the seafloor. As for the other two pesticides (permethrin and cypermethrin), 28 of the 32 drums were located near the wreck and brought to the surface. Despite the 4 missing containers, it was decided to abandon search operations. Given the low solubility of these substances, they were not expected to lead to any extensive pollution if they were to leak from the drums. Fishing activities continued to be heavily disturbed for 3 to 4 weeks. Upon the initiative of the French and British governments, a monitoring programme was conducted over several years on water, fish and shellfish samples. No lindane pollution was ever discovered.
