Fate and weathering facts observed/reported
Slight release of acrylonitrile. In seawater, acrylonitrile dissolves and evaporates. An exclusion zone of ten mile radius was set up around the wreck. During the following days water samples were taken around the wreck at various depths. Four days after the incident a trace of acrylonitrile was found 500 m from the wreck’s position. Five days after sank, acrylonitrile concentration rose to 2.7 ppm around the wreck. Acrylonitrile is toxic, flammable and explosive, giving off toxic fumes (HCN) in the event of fire. Recovery of 900 m3 of acrylonitrile mixed with water from the 549 T transported.

Fate and weathering facts observed/reported
1,2-Dichloroethane is an oily liquid, flammable and toxic; marine pollutant and animal carcinogen. Combustion products include hydrogen chloride and phosgene. Its vapours are heavier than air and spread over the ground. They can cause dizziness and can be poisonous if inhaled. From the 3013 T of 1,2-Dichloroethane transported, 2,750 T were recovered.
