Between 1955 and 1970, the United States passed five laws to monitor and regulate the country’s air pollution. Each act built upon the last and, in 1970, Congress passed the Clean Air Act, which established guidelines for “safe” levels of ambient air pollution, some of which are still used today.
But a new study suggests those standards may be too high, and as a result, children across the U.S. exposed to “safe” levels of pollution may be experiencing adverse effects to their brain development.
The study, published earlier this week in Environment International, hinges on an analysis of two sets of MRIs of children’s brains from one of the largest long-term studies of brain health and child development in the country.
