The Effect of Accidental Sulphuric Acid Leaking on Metal Distributions in Estuarine Sediment of Patos Lagoon

摘要

In August of 1998 the tanker BAHAMAS belonging to the Chem Oil Company containing 12 000 t of concentrated Sulphuric acid, had an accident on board, after which es- Tuarine water entered one of the compartments of the tan- Ker, resulting in a vigorous exothermic reaction. The Reaction of acid with the metallic interior hull of the ship And the accompanying heat and H_2 production resulted in An imminent risk of explosion. To avoid an explosion, given The fact that neutralization was not possible, some of the Cargo was discharged into the surrounding water. Neu- Tralization was done in January 1999, after the acid con- Centration in the tanker had decreased and the Concentrations of Fe, Cr and Ni remained elevated.
