United States: The research reveals that brief exposure to air pollution produces adverse effects on human focus for managing everyday responsibilities.
More about the news
A research team conducted pre-post cognitive tests on 26 participants who received either high PM concentration from candle smoke exposure or clean air for one hour.
High particulate matter (PM) concentrations exposed to the participants for brief periods negatively impacted their selective attention and emotion recognition abilities no matter how they accessed the air through normal breathing or just through their mouths, according to findings published in Nature Communications.
PM pollution interferes with a person’s attention span during work activities and social scenarios.
According to Dr Thomas Faherty of the University of Birmingham, a co-author of the study, “Participants exposed to air pollution were not as good at avoiding the distracting information,” the Guardian reported.
“So that means in daily life, you could get more distracted by things. Supermarket shopping is a good example … it might mean that you get more distracted by impulse buys when you’re walking along supermarket aisles because you’re not able to focus on your task goals,” Faherty added.

What more has the data suggested?
Data showed participants suffered impaired emotional recognition abilities during cognitive tests afterward when they experienced PM air pollution exposure.
“They were worse at perceiving whether a face was fearful or happy, and that might have implications for how we behave with other people,” Faherty added.
Furthermore, “There are associative studies looking at short-term air pollution and incidents of things like violent crime, especially in US cities. So you could kind of tentatively link those things together, possibly saying that the reason for that might be some kind of emotional dysregulation,” he continued.
Research data revealed no modification in working memory performance, demonstrating that several brain functions demonstrate better short-term pollution resistance compared to others, the Guardian reported.
The influx of airborne pollutants is positioned among the leading environmental determinants of public health conditions worldwide. Outdoor air contamination results in about 4.2 million premature yearly deaths worldwide, according to the World Health Organization.
The research team asserts that their study results establish important economic as well as societal implications that may influence educational achievement and workplace performance.
