Diesel gives city-dwellers wrinkles and blotches

Or so reported the Sunday Times, saying that the tiny particles and toxic gases emitted mainly by diesel vehicles attack the skin.

The report adds that such pollutants are already known to damage the lungs and heart, causing inflammation that raises the risk of asthma, heart attack and stroke. The data is based on five studies, two in Germany and three in China, comparing the skin of people living in polluted cities with those in suburban and rural areas. What happens is that the tiny piece of soot is covered by an oily coat of unburnt fuel which lets particles break through the skin’s protective outer layer
