In a press release, the ministry reports that the preliminary assessment points to "a potential small discharge, of unknown origin, but probably of origin south of Luanda Island", which was reported on Thursday night.
The preliminary assessment was made this Thursday by a team from Operation Transparency at Sea (Luanda Port Authority, Fisheries and Marine Research Institute, Spillage Unit, Ministry of Mineral Resources and Oil and Fiscal Police)
"The stain of the discharge in the water was not located, so it is believed to have been overcome by the mechanical action of the waves that broke the hydrocarbons and allowed their rapid dissolution in the body of water," the statement said.
The spill happened on the beaches located between the roundabout of the Pumangol gas station and the restaurant Jango Veleiro, on Luanda Island.
The ministry will carry out additional tests in partnership with other ministerial departments "to reach more in-depth conclusions," publishing the results after the end of the investigation.
