High concentrations of the so-called ultra-fine particles in the air were found by scientists from the border regions of Poland, Slovakia, and the Czech Republic, collaborating on the Air Tritia project.
Absorption of such particles can lead to lung cancer.
The findings confirm the need to reduce municipal and transport emissions, according to a representative from the Central Mining Institute (GIG) in Katowice, southern Poland.
Particles smaller than 0.1 microns are called “ultra-fine particles,” the spokesperson added.
Launched in 2017, the Air Tritia project runs an international consortium and aims to create tools and a support system to improve air quality in the border region.
