§ Mr. Watson
To ask the Secretary of State for Transport what continuous monitoring of blood lead levels in children is carried out by his Department; and if he will publish the reports for the last three years for which information is available. 
§ Mr. Norris
Monitoring of levels of lead in children is a matter for the Department of Health. However, I understand that monitoring programmes have shown a continuing fall in blood lead levels. This is in part due to the Government's successful policy of encouraging the use of unleaded petrol.
