Exhaustive investigation tests for lung damage

February 6, 1998

Ken Donaldson, professor of biological science at Napier University, is heading a Pounds 110,000 initiative to investigate how microscopic particles from vehicle exhausts are damaging the nation's lungs.

Previous studies have estimated that more than 10,000 people may die each year in the United Kingdom from lung problems caused by these particles.
