HC Deb 09 February 1971 vol 811 cc126-7W
Mr. Hayhoe

asked the Secretary of State for Trade and Industry whether he will now make a statement about the pollution measurement tests carried out at Heathrow Airport last year.

Mr. Noble

The tests were conducted by the Warren Spring Laboratory during the period June to September, 1970. The broad conclusion reached was that less pollution is caused by the airport than would be generated in an average urban development covering the same area. A summary report of the findings has been placed in the Library.
