According to the World Health Organisation (WHO), about 88 per cent of premature deaths in low- and middle-income countries in Asia can be attributed to air pollution. In New Delhi, average black carbon concentration in cars was up to five times higher compared to Europe or North America.6 times higher fine particle levels than people in European and American cities.D13.The study found evidence that pedestrians walking along busy roadsides in Asian cities are exposed to up to 1.The number of road veh-icles in Beijing increased from 1.5 million in 2000 to more than 5 million in 2014 and the number in Delhi is expected to inc-rease from 4."There are increasing efforts in Asia to install properly designed and calibrated portable monitoring systems to measure actual exposures," said Chris Frey of North Caro-lina State University.Car drivers in Asia are exposed to up to nine hex nuts times more pollution than Europeans and Americ-ans, while black carbon levels were seven times higher for Asian pedestrians than Americans.Researchers from Unive-rsity of Surrey in the UK focused on the levels of fine particles, black carbon produced by carbon-rich fuels such as gasoline and diesel fuel, and ultrafine particles (UFP) small enough to travel deep into a citizen’s lungs.London: Travell-ing by car in Delhi exposes people to black carbon levels five times higher than Europe and America, say scientists who found that Asian residents are expos-ed to nine times more air pollution than their Western counterparts.The study reported that in Hong Kong, UFP levels were up to four times higher than in cities in Europe.7 million in 2010 to 25.6 million by 2030.In a study published in the journal Atmospheric Environment, researchers looked at studies of pollution exposure and concentration levels in Asian transport microenvironments (walking, driving, cycling, motorbike riding and bus riding)
