Detect ominous effects of air pollution on the brain

Research by the London School of Economics (UK) based on 2,400 students of their own shows that polluted air seems to have mysterious and worrying effects on the human brain.

The scientists analyzed a fine airborne dust called PM10. When its level in the exam rooms violates the World Health Organization (WHO) safety standards, students immediately score less than 2% when compared to their true ability.

In some exam rooms, PM10 concentration up to 75 micrograms / cubic meter, or half the WHO standard (50 micrograms / cubic meter), the students reduced points by 3.4%.

The study did not explain the cause and mechanism of this disturbing impact, but it was enough to set off a new warning bell about the negative impact of air pollution , especially on the attack of objects. particulate matter, including PM10 fine particles and PM2.5 ultrafine particles, which experts say penetrate the mask. The main source of particulate matter is transportation, so fine dust pollution is one of the top concerns in big cities like London.

Lead author Sefi Roth advises that parents and students should be aware of the dangers of air pollution on these important test dates for the above reasons .

Last year, a study from Peking University (China) based on nearly 40,000 people showed that air pollution can lead to cognitive decline, making you less able to math and language expression. .
