Launching Air Quality Measurement Campaigns in Metro Sevilla

In an effort to enhance air quality and ensure passenger health, Seville's Metro has launched an ambitious air quality measurement campaign has been initiated in. Utilising cutting-edge technology, this initiative will implement a monitoring system will be implemented to thoroughly assess the air quality of the underground environment.

In partnership with the University of Seville and boasting a total of 21 stops along its line, Seville's has undertaken to task of maintaining a healthy and safe environment for the thousands of daily users of this means of transportation.

The parameters being monitored include temperature, humidity, carbon dioxide (CO2) concentration, total volatile organic compounds (TVOCs), fine particulate matter suspended in the air (PM2.5), ozone, and NO2.

Each train consists of 5 passenger cars and operates hours from 6:30 am to 11:30 pm. Field measurements will be conducted for 1 week during different seasons: winter, spring, and summer. This approach will enable a comprehensive representation of seasonal and situational variations that may impact underground air quality.

Additionally, a detailed census of passengers boarding or disembarking at each station will be conducted. This will enable an accurate estimation of passenger numbers on different sections of the route. The significance of this project lies in the health and well-being of metro users. Prolonged exposure to elevated levels of CO2, TVOCs, and PM2.5 can adversely affect respiratory and general health. By understanding and addressing these issues, Seville's Metro is demonstrating a proactive commitment to the safety and comfort of its passengers.

The results of these measurements will not only help identify areas for improvement but will also serve as a reference for future initiatives aimed at optimising air quality in public transport.
