Vehicle pollution 'results in 4m child asthma cases a year'
|The Guardian & ...||•||April 15, 2019|
Equivalent of 11,000 new cases a day occur worldwide due to toxic air from traffic, researchers say.
Reported in the Guardian newspaper, four million children develop asthma every year as a result of air pollution from cars and trucks, equivalent to 11,000 new cases a day, a landmark study has found.
Most of the new cases occur in places where pollution levels are already below the World Health Organization limit, suggesting toxic air is even more harmful than thought.
The damage to children's health is not limited to China and India, where pollution levels are particularly high. In UK and US cities, the researchers blame traffic pollution for a quarter of all new childhood asthma cases.
Canada has the third highest rate of new traffic-related asthma cases among the 194 nations analysed, while Los Angeles and New York City are in the top 10 worst cities out of the 125 assessed. Children are especially vulnerable to toxic air and exposure is also known to leave them with stunted lungs.
The research, published in the journal Lancet Planetary Health, is the first global assessment of the impact of traffic fumes on childhood asthma based on high-resolution pollution data.
Due to their high populations and pollution levels, the top three countries for the total number of new children getting asthma each year are China (760,000), India (350,000) and the US (240,000). The scientists said their research may underestimate the true levels in many poorer nations where asthma often goes undiagnosed.
