§ Mr. Morgan
To ask the Secretary of State for the Environment what proposals he has for improving the accuracy of measuring fine particulate matter and benzene arising from vehicle exhaust emissions.
§ Mr. Atkins
The improvement of the accuracy of measurements of particulate and benzene in vehicle exhausts depends on the continuing development of measuring equipment. Contractors making these measurements for my Department will be expected to use the most up-to-date and accurate techniques practicable.917W
