A recent research by scientists has revealed that people travelling in a car in Delhi are exposed to black carbon levels five times higher than Europe and America.

The report further stated that the Asian residents are exposed to nine times more air pollution than their Western counterparts.

It said that people travelling in cars in Asia were exposed to up to nine times more pollution than Europeans and Americans while black carbons levels were seven times more for Asian pedestrians than Americans.

A World Health Organisation (WHO) report said that about 88 per cent of premature deaths in low and middle-income countries were caused by air pollution.

The number of road vehicles in Beijing increased from 1.5 million in 2000 to over 5 million in 2014. The numbers in Delhi are expected to rise from 4.7 million in 2010 to 25.6 million by 2030.

The study was published in the journal Atmospheric Environment and was based on studies of pollution exposure and concentration levels in Asian transport microenvironments. 

The researchers from the University of Surrey in the UK focussed on the levels of fine particles, black carbon produced by carbon-rich fuels such as gasoline and diesel fuel, and ultrafine particles (UFP) which are tiny enough to penetrate in the lungs of the people.

The study further said that the pedestrians walking along the busy roadside in Asian cities are exposed to 1.6 times higher fine particle levels than people in European and Amercian cities. 

The studies were limited to cars as rare data was available on cyclist and motorcyclist exposure despite substantial use in Asian cities. 

Chris Frey of North Carolina State University in the US said that increasing efforts were made in Asia to put up properly designed and calibrated portable monitoring systems to measure actual exposures and prevent them.
