New research shows that the more serious the air pollution, the worse the student’s test scores
According to foreign media reports, a new study conducted by British scientists recently showed that students exposed to high air pollution may lead to worse test scores. Air pollution has long been associated with harmful side effects, leading to respiratory problems, heart and liver dysfunction, fatigue, headaches and reduced life expectancy. Now, a new study suggests that this effect will expand further and may have a negative impact on brain activity.
Researchers at the London School of Economics and Political Science performed statistics on the results of more than 2,400 students taking the test and compared the air pollution levels in the test rooms. As a result, students’ test scores may drop by 3.4% in a highly polluted environment where PM10 exceeds 75 micrograms per cubic meter.
The project also conducted another study based on 400,000 exams for Israeli youth. The researchers found that the PM2.5 concentration in the examination room was equal to or higher than 23.5 micrograms per cubic meter, which may result in a 3% drop in test scores.
Researchers suggest that students should be exposed to extreme air pollution in the days when they have exams.
