The problem will not only be the increase in PM (particulate matter) concentration, but also the increase in NO₂ (nitrogen dioxide) concentration.

PM comes from both natural and anthropogenic sources, such as vehicle emissions in Madrid. If increases in natural PM and NO₂ are expected, the main source of which in cities is traffic, perhaps the recommendations should go beyond limiting outdoor activities and consider traffic restrictions if the health of citizens is to be protected.
