“We could need to be particularly cautious to guard them from publicity, so we will enhance their outcomes later in life,” Garcia stated.
Researchers famous that individuals with grownup bronchitis signs have been affected by nitrogen dioxide as children despite the fact that common childhood publicity fell far under annual EPA requirements — only a bit over half the restrict set in 1971 that also stands at the moment.
The findings have been revealed June 28 within the American Journal of Respiratory and Scientific Care Drugs.
“This examine highlights the significance of reducing air air pollution, and particularly publicity throughout the important interval of childhood,” Garcia stated. “As a result of there’s solely a lot that we will do as people to regulate our publicity, the necessity to defend kids from the antagonistic results of air air pollution is best addressed on the coverage stage.”
