The 2006 Côte d'Ivoire toxic waste dump was a health crisis in Côte d'Ivoire in which the "Probo Koala", a ship registered in Panama and chartered by Trafigura, hired a local contractor to offload waste in Abidjan after refusing to pay a €1,000 per cubic metre surcharge imposed by Amsterdam Port Services to discourage waste disposal in the Netherlands. The local contractor, Tommy, improperly dumped the waste materials at as many as 12 sites in and around the city of Abidjan in August 2006. The gas caused by the release of these chemicals is blamed by the UN and the government of Côte d'Ivoire for the deaths of 17 and the injury of over 30,000 Ivorians, with injuries that ranged from mild headaches to severe burns of skin and lungs. Almost 100,000 Ivorians sought medical attention after prime minister Charles Konan Banny offered free medical care in Abidjan’s hospitals to the city’s residents.
