Measuring Air Quality With Pine Needles

Did you know that if you went hiking through a forest of evergreen trees, you would actually be surrounded by air quality monitors? A recent University of Utah study finds that air quality can be monitored throughout the year by analyzing the magnetism of pine needles. The study shows that pine needles containing higher concentrations of magnetic particles are more exposed to pollution than pine needles with lower concentrations.

Using pine needles as a natural air quality monitor can serve as an innovative way to expand air quality measurements leading to a clearer picture of pollution patterns in certain regions. Dr. Gannet Hallar and the HART team are excited to be involved with the project. Check out the link below to read the full story.
