Soil contamination by heavy metals in vineyard of a semiarid region: an approach using multivariate analysis

Contamination of vineyard soils by the continuous use of cupric fungicides and fertilizers has been a worldwide concern. The objective of this study was to determine the total concentration of Cu, Zn, Fe, Mn, Ni and Pb from vineyard soils of a semiarid region in Brazil. Soil samples at 0–20 and 20–4...
