2015 – Touching Air: Necklace Shows Air Pollution


This necklace made by Stefanie Posavec and Miriam Quick shows one week of air quality data measured in the city of Sheffield. Each segment is a period of 6 hours, and its appearance conveys the concentration of particulate matter during that period of time. A low concentration yields a small, round, green segment. A high concentration yields a large, spiky, red segment.
