§ Sir Hugh Rossiasked the Secretary of State for Trade and Industry if work at the National Physical Laboratory on the corrosion of metals by air pollutants has been started.
§ Mr. Butcher[pursuant to his reply, 8 July 1985]: NPL is carrying out a survey on the effects of atmospheric pollution on the corrosion of metals, in order to quantify changes in rates of corrosion consequent on changes in levels of pollution over the years, and to make recommendations on further work required to facilitate cost-benefit calculations. NPL has put proposals to the Department of the Environment for research on atmospheric corrosion and these have now been agreed. The NPL expects to commence work shortly.
