摘要: Sixteen bottom sediment samples collected from Qua-Iboe River estuary and associated creeks were analyzed for Cd, Cr, Cu, Fe, Pb, Zn, Ni, pH, Organic carbon (orgC),and grain size in order to assess the current pollution status of study area. Concentration data processed using Pearson correlation analysis. Sediment assessment was carried out Enrichment factor, Geo-accumulation index Modified degree contamination. The calculated enrichment factor showed that enriched with Cu Pb. results geo-accumulation (Igoe) indicated sediments are unpolluted moderately polluted strongly Cd extremely Ni. This attributed mainly oil contaminating wastes metal scraps. modified contamination (mCd) revealed Qua Iboe fall between 8 ? mCd 16 indicating very high
