The precautionary principle and regulation of chemicals

This dissertation presents a combined approach to the study of discourse and technology. The approach is applied on two different cases involving the precautionary principle and chemicals; namely an in-depth analysis of a short-lived prohibition against a specific class of pesticides based on conflicting sciences, and a broader analysis of the development of chemicals regulation and the interrelation to the precautionary principle. It is concluded that the precautionary principle in practise requires a vivid debate at all levels including scientific approaches and public deliberation.
