Pedaling Through Pollution

Avoiding belligerent bus drivers or unwitting tourists popping out of taxis are just a few of the more obvious risks of riding a bike through city streets. Yet there could be another inconspicuous and nearly unavoidable danger that could take a toll on your health: air pollution. Identifying how hazardous exercise can be in an urban environment filled with noxious particles in the air is the goal of a new study by Columbia University researchers Steven Chillrud and Darby Jack. Using biometric sensors, a wearable pollution monitor, and GPS, the study will detail participants’ exposure to toxins as they cycle through city streets.
