Air Pollution Affects Kids’ Working Memory/RNN

Ouch.  Kids walking to school in dirty air feel the affects in their lungs and, under this study, in their brains.

Of course some kids may now use air pollution as an excuse for bad grades.  Not a bad line.  But as playful as this scenario might get, bad environmental conditions diminish our health--period.

Do we want our kids wearing masks to school?  Is that the solution?  Cans of clean air.  Or, do we speed ahead with a clean energy plan that restores good air quality for all?  What is the better, long-term strategy?  Is that a worthy industrial revolution?

A study led by the Barcelona Institute for Global Health (ISGlobal), an institute supported by the “la Caixa” Banking Foundation, has demonstrated that exposure to air pollution on the way to school can have damaging effects on children’s cognitive development. The study, published recently in Environmental Pollution, found an association between a reduction in working memory and exposure to fine particulate matter (PM2.5) and black carbon during the walking commute to and from school.
The study was carried out in the framework of the BREATHE project. Previous research in the same project found that exposure to traffic-related pollutants in schools was associated with slower cognitive development. The aim of the team undertaking the new study was to assess the impact of exposure to air pollution during the walking commute to school. The findings of an earlier study had shown that 20% of a child’s daily dose of black carbon — a pollutant directly related to traffic — is inhaled during urban commutes.
“The results of earlier toxicological and experimental studies have shown that these short exposures to very high concentrations of pollutants can have a disproportionately high impact on health” explains Mar Álvarez-Pedrerol, ISGlobal researcher and first author of the study. “The detrimental effects may be particularly marked in children because of their smaller lung capacity and higher respiratory rate,” she adds.
The study was carried out in Barcelona and enrolled over 1,200 children aged from 7 to 10, from 39 schools, all of whom walked to school on a daily basis. The children’s working memory and attention capacity was assessed several times during the 12-month study. Their exposure to air pollution over the same period was calculated on the basis of estimated levels on the shortest walking route to their school....
