HC Deb 12 October 1976 vol 917 c84W
Mr. Hugh Jenkins

asked the Secretary of State for the Home Department for how long baboons have been used in connection with the effects of lead in petrol; if they have suffered any ill-effects; if the use of these animals is continuing in such tests; and, if so, to what extent.

Dr. Summerskill

We are not aware from records that any experiments concerned with the effects of lead in petrol have been carried out on baboons in the United Kingdom but I will investigate any case known to my hon. Friend.
