Human hair can be a tool for measuring the toxicity of a city, according to London-based architects Deborah Lopez and Hadin Charbel, who have also created a textile made from hair.
Through their research studio, Pareid, Lopez and Charbel have been analysing hair samples as a way of mapping the levels of pollution across different areas of Bangkok. Samples containing larger quantities of heavy metals indicate higher levels of environmental toxicity.

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.
