Using Principal component analysis (PCA) to interpret geochemical composition of toxics waste

The Ivorian Antipollution Center discovered the toxics Waste from Probo Koala boat in 21 August, 2006. This boat had been used to refine oil named naphta of cokéfaction by Trafigura firm in the sea. The process of refine consist to caustic sodium carbonate washing and produced toxics waste. These toxic wastes have been unloading in 13 zones of the Abidjan district: Akouédo, Abobo, Abobo Alépé road (DJIBIvillage), civile prison road (MACA), industrial zone of Koumassi, Port-Bouët - Vridi CAP Logistic (Rue Saint-Sylvestre) … This situation caused a socio-political crisis and generated the death of many people. The first analyses showed that the substances coumpound of toxic waste are a petroleum factory origin. In the aim to know the environmental impact of these pollutes in Abidjan district (IvoryCoast) the samples of these toxic wastes have been sent to analyses in Wesling laboratory in France. These experiences showed thatthe toxic waste contain the Polycyclics Aromatics Hydrocarbons (PAH), the Volatile Aromatics Compound (VAC), the Mercaptans and sulphur molecules Aliphatic hydrocarbons, Linear hydrocarbons, Total Petroleum Hydrocarbons (TPH), Mercaptans, sulphur and also heavy metals.
