HC Deb 16 February 1983 vol 37 c192W
Mr. William Hamilton

asked the Secretary of State for Social Services if he will publish the evidence available in his Department concerning the adverse effects on the intelligence quotient of children subjected to high lead ingestion from petrol.

Mr. Geoffrey Finsberg

It is customary for medical researchers to publish the results of their work in medical and scientific journals. The results of all research known to Government into the neuropsychological effects of lead either has been published or, I anticipate, will be published in this way. This research relates to the effects of lead accumulated in the body from all sources.
