Six people have now died from the toxic waste dumped in the biggest Ivory Coast city, Abidjan, while 9,000 have sought treatment, the government says... The waste came from the ship, the Probo Koala [owned by Prime Marine], and has been found in some 10 open-air sites around Abidjan... The company which [chartered] the ship, Trafigura Beheer BV, says it is extremely concerned and has sent oil and mining experts to Abidjan to help the authorities. It says it informed the authorities and handed over discharges from washing out its oil tanks with caustic soda - known as slops - to a certified local company, Compagnie Tommy.
