Using Principal Component Analysis to Assess Water Quality from the Landing Stages in Coastal Region

Principal component analysis (PCA) was used to comprehensively evaluate the relationship between physicochemical and bacteriological parameters of water on banks Wouri. At each sampling station, focused Water temperature, pH, dissolved oxygen, CO2, electrical conductivity, suspended solids, nitrates, ammonium ions, orthophosphates, color, salinity, turbidity. The consisted isolation heterotrophic aerobe bacteria (HAB), faecal bacteria, some pathogenic bacteria. PCA showed that two factorial axes F1 (49.48%) F2 (25.18%) explained 74.67% total inertia. Suspended Solids, conductivity color are significantly positively correlated with other also axis. HAB, Shigellae, CO2 salinity and, negatively axis previous group variables. discriminates in negative coordinates Youpwe 1 2 stations, characterized by a high content low oxygenation. There is concentration such as coliforms Salmonella. calculation FC/FS ratio reflects exclusively contamination animal origin all sampled stations.
