As can be seen in this post, the NOx concentration has been monitored since before the implementation of the final product in the street by using passive air sampling tubes. These tubes have been placed in different heights and the results have been analyzed by the UPM staff.
Both in the beginning and in the last part of the Project LIFE-Photoscaling, the producers of photocatalytic materials and companies ralated to this sector have been surveyed in order to know their new insights about their market, their exports, changes in attitude detected… The results have been processed and studied in the Project.
Today, staff of Universidad Politécnica de Madrid (UPM), Madrid City Council and Eduardo Torroja Institute for Construction Science has met to organise the final tasks of LIFE @photoscaling project.
The pilot site is cleaned with water periodically simulating normal street cleanings. Madrid City Council staff water the pavements and the sidewalks and, then, activity tests (NBT, colorimetry tests, nanoparticles, …) are performed before and after these cleanings by workers of Institute Eduardo Torroja.
Tests of emission of nanoparticles in José Antonio de Armona street with TEMIS·1000 after placing the photocatalytic material, over both surfaces: asphalt and pavement tiles. For a complete information about TEMIS·1000, click in this link.
Today, the photocatalytic activity has been checked out again with “in situ” tests of NOx degradation. After more than one month, the effectiveness keeps on being as good as initially.
We have been back to the pilot site and the reference surface to measure and collect samples of nanoparticles using different methods.

After waiting for a few days for the chosen material to settle, we have been to José Antonio de Armona Street (pilot site) and to Bernardino Obregón street (reference surface) to perform tests and collect samples. We will compare the results from the tests performed on the pilot site and the reference surface, which will allow us to determine the effectiveness of the chosen material […]

Two AQmesh sensors have been installed in each street (José Antonio de Armona and Bernardino Obregón). These sensors, which have been used during almast the whole LIFE-Photoscaling Project, can measure four gases: CO, NO, NO2, O3.
