At the moment virtually everyone is affected by the Corona Pandemic. If it gets really bad, we know infected people in our social environment. We would like to take this …
On New Year’s Eve, 31/12/2019, and New Year’s Day, 01/01/2020, we set up a fine dust sensor to monitor air quality at Keizer Karelpark Oost in the centre of Amstelveen, the Netherlands, to measure the effects of fireworks on local air quality. At the same time, air quality was also monitored in our offices in an industrial estate in the south-west of Amstelveen.
Besides temperature and humidity, PM1, PM2.5, PM10 and TSP (total particulate matter) were measured.
PM concentrations in the office air reached their first small peak around 21:00 and their second, clear peak at 03:30 in the morning with almost 120 μg/m³.
Conclusion: fireworks activities at the turn of the year affect the air quality in the office drastically.
