Effects of traffic air pollution on children

Given the great variety of substances present in the atmosphere, numerous classification methods have been proposed: firstly it can be classified according to the chemical composition, for which we mainly speak of compounds that contain sulfur, compounds that contain nitrogen, which contain carbon and halogen compounds.

Secondly, it can be classified according to the physical state: gaseous, liquid or solid; finally, it can be divided according to the degree of reactivity in the atmosphere, into primary or secondary substances. The main effects that pollutants cause in the environment are the greenhouse effect, and acid rain, then of course they also lead to other problems such as the ozone hole and other less visible problems on human health, but also on flora and fauna.

The Effects of Traffic Air Pollution in and around Schools on Executive Function and Academic Performance in Children: A Rapid Review, published on the International journal of environmental research and public health, told: "This review summarizes the extant literature investigating the relation between traffic-related air pollution levels in and around schools and executive functioning in primary-school-aged children.

An electronic search was conducted using Web of Science, Scopus, and Education Literature Datasets databases. Review articles were also searched, and forwards and backwards searches of identified studies were performed. Included papers were assessed for quality.

We included 9 separate studies. Findings suggest that indoor and outdoor particulate matter with a diameter of 2.5 μm or less (PM2.5 ) negatively influences executive function and academic achievement and that indoor and outdoor nitrogen dioxide (NO2) adversely affects working memory.

Evidence for the effects of particulate matter with a diameter of 10 μm or less (PM10) is limited but suggests potential wide-ranging negative effects on attention, reasoning, and academic test scores. Air pollution in and around schools influences exec utive function and appears to impede the developmental trajectory of working memory.

Further research is required to establish the extent of these effects, reproducibility, consequences for future attainment, and place within the wider context of cognitive development."
