The results of 27 trace elements, namely, Ag, As, Au, Ba, Bi, Cd, Co, Cr, Cu, Fe, Ga, Hg, La, Mn, Mo, Ni, Pb, Sb, Sc, Se, Sr, Te, Th, Tl, U, V and Zn in 49 soil samples collected on a uniform 3 km × 2 km grid pattern over Dagbala-Atte District were subjected to some univariate and multivariate statistical evaluation. The univariate methods used include frequency distribution and dispersion boxm plots while the multivariate methods employed are correlation and factor analyses. Frequency distribution and dispersion box plots revealed that most elements showed mixtures of populations and are log-normally distributed in varying degrees at 95% confidence level. Eventually, the univariate statistics was applied to compute the threshold values for all the elements in the District, w... view more»
