Australia: Warning about air pollution in the classroom

The atmosphere in some schools' classrooms may contain contaminants in the form of dispersed microscopic particles, which are easily absorbed into the lungs by breathing, much higher than outdoor air.

The conclusion is published by Australian and German scientists, published in the journal Environmental Science & Technology.

Lidia Morawska and colleagues have demonstrated that in the past few years, the impact of granular contaminants on health has increased over the lung. Most researchers focus on understanding these invisible aerosols in outdoor air, especially due to emissions from vehicles. They pay little attention to finding them in the indoor atmosphere, which is actually more often than outdoors. Classes, places where students gather almost all day in large numbers, is where the atmosphere is highly polluted.

During extracurricular sessions, 'learning with' onions', scientists examined the amount of contaminants in the form of microscopic particles at the Primary School in Brisbane, Australia. They found that in most cases, the level of pollution in classrooms was much higher than outdoors. The highest level in the hours you learn about painting, drawing, even crafting due to components in glue, paint . accumulates.

A significant part of the pollutant in the form of particles is derived from detergents used to clean the classroom.
