The application of several chemometric topics in connection with an environmental study is described. A two‐way ANOVA is used to show the irregularity of the distribution of heavy metals in the rural soils around a lead smelter. Multivariate statistical methods are also applied to show significant correlations between metals and the wind direction. Principal components analysis and Varimax rotation seem to confirm the validity of the conclusions.
