摘要: Chemometric or multivariate techniques were applied to identify the spatialvariation and pollution sources of Jakara River Kano-Nigeria. Thirty water sampleswere collected: twenty three along Getsi seven surface samples alongthe main channel Jakara. Twenty quality parameters namely: pH,temperature, turbidity, electrical conductivity, dissolve oxygen, biochemical oxygendemand, Fecal Coliform, total solids, nitrates, phosphates, cobalt, iron, nickel,manganese, copper, sodium, potassium, mercury, chromium, cadmium, lead,magnesium, calcium analyzed. Hierarchical cluster analysis (CA) groupedthe sampling points into clusters based on similarities river qualitycharacteristics industrial, domestic agricultural sources.Forward backward Discriminant (DA) effectively discriminate five andfifteen variables respectively with 100% each correct assigning from theoriginal variables. PCA/FA used investigate origin eachwater due various land use activities, principalcomponents obtained 77.5% variance, in addition PCA threelatent convinces support CA.
