Ekosphere - Iker Aranjuelo: "The industry has gone out of the cities; the main source of pollution in urban areas are cars"

At the Agrobiotechnology Institute of Navarra, the FitoRastreando project has been developed. It’s a great way to measure air quality. Researchers have distributed plants so that people from many places can take care of them. And this plant, when it grows, has received substances that are in the local air. These plants have been analyzed, and so they have been able to measure the air quality itself. The researcher Iker Aranjuelo Mitxelena tells us about the project.
