asked the Secretary of State for the Environment what arrangements he is making to analyse the level of lead found in the blood of police officers; how many police volunteers he expects to invite to offer blood samples for this purpose in each of the years 1983 to 1986, respectively; and if he will make a statement.

Preliminary approaches have been made to the Police Federation, the Police Superintendent's Association and the Association of Chief Police Officers in the context of the Department's research programme in the lead field over the next few years. As yet there are no definite arrangements.
