Are there good open-source components for air quality monitoring, e.g multiple sensors that work with a common software platform, for continuous data collection and analysis? Ideally something that works with low-cost boards like ESP32.
I can write something about it if there's any interest.

The linked DIY instructions give you a basic board with PM 2.5 particles, temp, humidity, and CO2. It is built on a Wemos D1 mini.
The founder (Achim) is very helpful.
If you wanted to use these plans to get started (including the software to power the Wemos), then buy whatever additional sensors you might like to add, it should be fairly simple.
That would be great.
https://sigrok.org/ can log data from basic CO2 monitors, maybe it could be extended to support the sensors you mentioned.
