A child's risk of developing allergies increases by up to 50 percent from pollution caused by traffic, a rate that increases the closer the child grows up next to major roads, a new study says.
Navtej Kohli Blogspot features the report:
The findings, published in the June issue of the American Journal of Respiratory and Critical Care Medicine, revealed significant links between the distance to the nearest road and asthmatic bronchitis, hay fever, eczema and allergic sensitizations.
Pollution and allergies have been linked in previous studies, but the association was often attributed to socioeconomic factors, not the distance from major roads.

Congestion charge does not cut pollution - Navtej Kohli
Navtej Kohli shares an interesting story. Recently he came across the following report based on a study that shows congestion charge does not cut pollution.
A new study has shown that city centre congestion charges do nothing to cut pollution or better the quality of air.
Researchers from King's College, London have concluded that the capital's charge, which was introduced in 2003 affecting couriers working the capital, has made no difference to levels of smog in the city as extra buses and taxis are using the roads.
Professor Frank Kelly, environmental health expert at the institute and the study leader, said: "The problem was that the central zone was only one per cent of the Greater London area.
"Even though it reduced the traffic by 40,000 vehicles a day, there was a dramatic increase in the number of buses."
Kelly added that the introduction of the low emission zone (LEZ) could see improvements to the air, with people undertaking courier work and other large vehicle drivers having to pay between £100 and £200 to enter most of London if their vehicles do not meet pollution standards.
Meanwhile, in what could be good news for couriers, plans to introduce a £25-per-day congestion charge for high emission vehicles could be scrapped by new London mayor Boris Johnson who pledged to abandon the initiative in his manifesto.
