Evaluation of Exposure Information

Abstract Steps toward the development of a generally applicable and deterministic model for retrospective exposure assessments are suggested. The first step is the introduction of a set of n universally applicable and mutually independent exposure modifiers, chosen according to first principles. The second step is the provision of a list of these exposure modifiers to be used in a multiplicative model. The historic concentrations can then be obtained from present measured concentrations by calculating backwards step by step. If some historic exposure data are available, they can be used as gauging points and the model parameters can be renormalized accordingly. The ranges of the magnitude of the various modifiers differ by several orders of magnitude. This should be considered when deciding which historic information should be traced. Information sources should be searched systematically for exposure-related data. The term industrial archeology is phrased, and this activity is illustrated with a dendrochr...
