For the view that devising criteria for registration and control purposes is a political, pragmatic business and not a matter for scientists or for scientific decision, see for example BennettD., “Workplace Health and Safety: A Case Study in Union Education,”The Industrial Tutor (U.K.), Vol. 4, No. 10, Autumn 1989. The most effective polemic against “science policy” is to be found, as usual, in CommonerBarry, Making Peace with the Planet; Pantheon Books, New York, 1990, Pages 70–78.
