Fine particulate matter harms human health. Based on a study and additional data (which we collected), we show which subway lines expose commuters to high values of PM2.5 particles.
The story was quoted in larger, more established yellow press media. The transport company, which did not provide us with any statements, ended up providing statements to larger media outlets.
What was the hardest part of this project?
We were intent on showing the Vienna subway map overlaid with measurement data, and then highlighting and “flattening” each line. Technically, this transition was the hardest part. Getting access to a PM2.5 sensor on a short notice (to validate our story and allow us to control for air conditioning on all relevant subway lines) and cleaning the raw measurement data was also a challenge.
Journalistically, reporting on the story correctly required lots of back-and-forth with scientists working on the fine particulate matter issue.
What can others learn from this project?
Gathering your own data often makes the better story.
