1,3-butadiene and carbon monoxide car emmissions cancer link

London: The development of cancer in childhood is strongly linked to pollution from engine exhausts, says a British researcher.

Professor George Knox, from the University of Birmingham, said yesterday that youngsters were at higher risk if they lived near emissions hotspots, such as transport depots.

But the statistical information manager at Cancer Research UK, Ruth Yates, said the results should be interpreted with considerable caution, saying much more research was needed to show what level of exposure posed a threat.
