The feasibility is explored of classifying human hair specimens according to their trace metal composition as determined by PIXE. Protons of 3.5 MeV were used to analyse 150 samples by energy-dispersive spectrometry using a Si(Li) detector. The methods of the Minimal Spanning Tree and Non-Linear Mapping were used to establish correlation among the specimens. As a result of distinct groupings obtained by these methods it was inferred that these techniques could usefully be applied to environmental pollution studies.
