HC Deb 25 July 1978 vol 954 cc663-4W
Mr. Litterick

asked the Secretary of State for the Environment what investigations his Department is now conducting to discover the lead content in the blood systems of people living in areas of high traffic density.

Mr. Denis Howell

The Department published last month the results of investigations into the blood lead levels of people living near the Gravelly Hill Interchange.

Work will begin early next year to measure the blood lead content of sample populations in all cities of over half a million people and also of critical groups who might be exposed to above average lead concentrations, including those living in areas where traffic is particularly heavy. Similar work is being undertaken in other EEC countries.
