§ Mr. Oakesasked the Secretary of State for Social Services to which local authorities a circular was sent requesting their medical officers to inquire into the lead content of the blood of persons living in the vicinity of factories where lead is 317W processed or used extensively; how many replies he has received; and what further action he is taking.
§ Mr. AlisonA circular letter by the Chief Medical Officer of my Department was sent to all medical officers of health in England on 21st December, 1971. I am sending the hon. Member a copy. At the same time medical staff from the Department contacted the medical officers of health of the 17 areas containing major lead works to discuss the possible problems in their vicinity and to offer advice and assistance. The surveys in these areas, which will take some time to complete, will show whether additional measures to reduce emissions are necessary.
