53 out of our 56 diffusion tubes were still in place at the end of the monitoring experiment and the results can be seen below. Our readings were bias-adjusted down to 83% of measured μg/m3, as recommended by the analysing laboratory.

Readings above 40 μg/m3 are in breach of EU air quality regulations.
