Scientists have proven that air pollution causes children to do worse in math exams.

Even minor changes in the environment have an impact. It is known that children's academic performance is associated with a large number of factors. These include the state of the air. DiscussScientists have proven that children do worse in math exams due to air pollution© Shiken

Scientists from the University of Oulu (Finland ) found out how different degrees of air pollution affect students' exam results. The results of this study were published in the journal Economics Letters.

The study was based on the analysis of data collected from the spring of 2006 to the fall of 2016. In total, the scientific work covered more than 370 thousand final exams, which were taken by 172,414 students from 253 schools in 53 cities and regions. These were exams in mathematics, physics, and the Finnish language.

But the composition of the air did not affect the rest of the exams.
