§ Mr. Spriggs asked the Secretary of State for Transport if he will encourage oil and spirit filter manufacturers to concentrate on production of filters which could filter lead from exhaust fumes.
§ Mrs. ChalkerAt least one United Kingdom manufacturer is developing a filter that could remove 301W about 50 per cent. of lead from exhausts. The Government's policy of reducing lead in petrol by 60 per cent. leaves open the longer term possibility of fitting filters to achieve a further reduction, if this is required.
