Airborne particulate matter and ground-level ozone are the two main components of smog. Most environmental agencies (including the BC Ministry of the Environment) routinely monitor these two air pollution indicators to assess overall ambient air quality. Exposure to airborne particles increases human mortality and morbidity from respiratory and cardiopulmonary diseases. While particles as small as 2.5 µm are now monitored in many BC locations, currently no system is in place to quantify much smaller particulates. It is evident that nanoparticles exhibit higher toxicity than micron size particles of identical substances. The proposed nanosensor is designed to fill the current gap in existing air monitoring and management systems.
