At the request of the Government of Côte d'Ivoire, UN Environment carried out an independent scientific environmental audit of the sites in and around Abidjan that were affected by the dumping of toxic wastes from the “Probo Koala” ship in 2006. The objective was to determine if these sites continued to pose risks to the environment or to public health, and to make recommendations about additional or corrective clean-up measures that would be needed in case contamination was detected. A UN Environment team of four international experts was deployed to Abidjan in July 2016 to undertake sampling of soil, water, air, sediment, molluscs, fruit and vegetables at 18 sites considered to have been affected by the dumping of toxic wastes, as well as at three control sites.UN Environment deployed teams of international experts to Abidjan in July 2016 and January 2017 to undertake sampling of soil, water, air, sediment, molluscs, fruit and vegetables at 18 sites considered to have been affected by the dumping of toxic wastes, as well as at three control sites. In total, 130 samples were collected and analyzed in internationally accredited laboratories. The full report of this audit presents the results of the laboratory analysis and the conclusions that can be drawn from them. It also provides a series of targeted recommendations to the Government of Côte d’Ivoire.
