Ever feel that the road gets a little too hot during when the sun is high, fearing that the heat could be hampering your health? It’s not just the temperature from the pavement you should be concerned about, but also the unseen that comes from it as a result. 

The latest study from the Yale University has found out that the material used in road and parking lots, asphalt, is actually causing both people and the environment some harm unwitting to the average person—especially, when it gets really hot.

Essentially a contributing factor to air pollution, researchers attribute the emitted particles from asphalt as a secondary organic aerosols (SOA) to which a pollutant called “PM2.5” heavily derives from. The polluting particle partially got its name to its size, which is 2.5 micrometer in all dimension.

Like all kinds of air polluting material, the PM2.5 is feared to pose a risk to public health, especially to those who have exposure to asphalt as part of day-to-day living. A belief that is solidly backed by tests which see the release of various organic compounds and that becomes significantly worse at higher temperatures.

Compounding further into the issue, it was found out that solar radiation also plays substantial part to the overall scheme.
