Urban Pollution Monitoring

This lecture presents a study on urban pollution in Lausanne, where volunteers equipped with sensor-filled backpacks aim to detect the most polluted areas of the city. The volunteers collect data on air quality, including nanoparticles, ultrafine particles, carbon monoxide, ozone, and nitrogen dioxide. The collected data will be used to map pollution levels in the city, benefiting the general public. Researchers plan to develop a smartphone application connected to portable sensors for real-time pollution monitoring, allowing users to track pollutant concentrations over time. The study involves 24 volunteers who have been participating for a year, and the initial results are expected in the coming months.
