HC Deb 01 March 1973 vol 851 cc395-6W
33. Mr. Judd

asked the Secretary of State for the Home Department whether he will make a statement on the research being undertaken by his Department into the inter-relationship of lead poisoning, its damage to the brain and consequential behavioural disorders which may be related to criminal behaviour.

Mr. Carlisle

Examination of the medical effects of lead ingestion, including possible behavioural effects, is primarily a matter for my right hon. Friend the Secretary of State for Social Services. I understand that a committee under the chairmanship of his chief medical officer is considering the physical effects of lead in the environment, including the possible mental effects of lead poisoning.
