Interesting article from Fast Company on the composition of dust and the potential hazards. I previously thought dust was mostly dead skin and benign beyond allergies:
Don’t feel bad if you’re clueless about your dust. Scientists are not that far ahead of you in terms of understanding the sources and health risks of indoor air particles. That’s an issue, because people spend a lot of time indoors. Indeed, the average American stays within four walls for almost 90% of their day. So knowing more about how your indoor environment affects your health is vital.
Overall, you can be sure that your dust also includes some decomposed insects, food debris (especially in the kitchen), fibers from carpet, bedding and clothes, and particulate matter from smoking and cooking. We hope our 360 Dust Analysis program will help solve more of the riddle of just what else goes into dust.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
