Air pollution found to be a risk to children's development

A study conducted by scientists from the Global Health Institute in Barcelona found that exposure to polluted air during childhood weakens connections between key parts of the brain. This was reported in an article published in the journal Environment International (EI).

Research results

Experts analyzed data from more than 3,600 children and identified serious problems associated with air pollution. In particular, it was found that high levels of air pollution lead to impaired functional connections between the cortical and subcortical structures of the brain. This can affect cognitive functions, movement and emotional control.

The children were measured for exposure to pollutants such as particulate matter (PM2.5, PM10) and nitrogen oxides (NO₂, NOx). Then, their brain activity was assessed at ages 10 and 14. As a result, it was found that children exposed to air pollution from birth to three years had reduced connectivity in the parts of the brain responsible for attention and movement control.

Long-term effects

The study's lead author, Monika Gooksens, noted that these changes may persist into adolescence. This suggests that there may be long-term negative effects on the development of children's neural networks.

The scientists also found that exposure to pollutants during pregnancy can lead to a decrease in the volume of the hippocampus, which is responsible for memory, in eight-year-old children. However, compensatory growth was observed in later years, indicating that the brain is more adaptable.

Air pollution measures

The researchers stressed the need to take measures to reduce air pollution in cities and minimize the negative impact on children's development. "Our results confirm that air pollution can have long-term effects on brain function. This once again highlights the need to introduce strict environmental standards," said study co-author Michel Kusters.
