§ Mr. Deakinsasked the Secretary of State for the Environment if he has received a copy of the report of the United States second national health and nutrition examination survey, which concludes that lead in petrol is a major factor in lead in blood levels among the general population; and if he will now arrange for the United Kingdom evidence on this matter to be re-examined.
§ Mr. Giles ShawAt present, only summaries are available of that part of the survey which touched on lead pollution. As soon as I have more details, they will be studied alongside such United Kingdom evidence as is available; but, generally, average United States blood lead levels have now come down close to those in the United Kingdom.
