It is a fact that fossil fuels from diesel cars and coal-powered fire stations cause dangerous tiny particulate pollution. Sooty air pollution in towns and cities increases the chances of women giving birth to small babies, new research has shown.
A study involving millions of births around the world found that higher pollution levels raised the risk of low birth-weight. Although small, the effect is said to be statistically significant. At national population scales it could have an important impact on child health, said the researchers. Babies are underweight at birth if they tip the scales at less than 2.5kgs, or 5lbs 8oz. They face an increased risk of dying in infancy, as well as chronic poor health and impaired mental development.
The new study, the largest of its kind ever conducted, focused on tiny sooty carbon particles called PM10s and even smaller PM2.5s which are known to be linked to heart and lung problems and early death. They originate from a number of sources, including diesel exhausts and the chimneys of coal-fired power stations and factories.
