Abstract
Target Transformation Factor Analysis (TTFA) has been applied to large data sets of trace element concentrations in lichens with the aim to resolve sources of environmental pollution. The concept of the princip al factor model is used in order to account for local variances in the data set. Monte Carlo techniques are used to estimate the uncertainti es in the obtained source profiles. It was found that the Monte Carlo method offers a new approach to the problem of the determination of th e number of factors to be used in the analysis.
