Sediments as monitors of heavy metal contamination in the Ave river basin (Portugal): multivariate analysis of data.

Abstract

The concentrations of heavy metals (Cd, Cr, Cu, Ni, Pb, Zn) were determined in river sediments collected at the Ave river basin (Portugal) to obtain a general classification scenery of the pollution in this highly polluted region. Multivariate data analysis techniques of clustering, principal components and eigenvector projections were used in this… (More)
