Urban Metabolism

May 20, 2016

What can a wastewater treatment plant tell us about the health of a population? Despite having a bad reputation for being the smelly place at the end of the pipeline, wastewater treatment plants are flush with a wealth of human health information. Rolf Halden, PhD, professor and director of the Biodesign Center for Environmental Security at Arizona State University can use the input and output from wastewater treatment plants to determine the health, lifestyle and consumption of a...

Innovative device traces chemicals affecting human and environmental health
