Poor indoor air quality linked with asthma development
Feb 24 2009
The research, conducted by the Johns Hopkins Bloomberg School of Public Health and the Johns Hopkins School of Medicine, is among the first to examine indoor pollution and examined the effects of both fine and coarse particles.
It discovered that for every 10 microgram increase of coarse particles per cubic metre of air, the number of days children suffered from increased coughing and wheezing rose by six per cent.
Meredith McCormack, who lead the study, explained: "We found that substantial increases in asthma symptoms were associated both with higher indoor concentrations of fine particles and with higher indoor concentrations of coarse particles."
The research was conducted among children from low-income backgrounds who spend the majority of their time indoors, German website Innovations Report informs.
In similar news, a study carried out by Utah's Brigham Young University found that an improvement in the US' air quality over the last 20 years has caused the country's life expectancy age to rise.
