Down the Drain

September 23, 2016

Rolf Halden, Ph.D., Director, Biodesign Center for Environmental Security We all worry about revealing too much personal information online, but can you imagine the wealth of information contained in a city's sewage? Hear how Halden and his team are using wastewater to reveal a city population's health, lifestyle and consumption. And millions of dollars’ worth of nutrients and metals are literally flushed down the drain. This is a Spirit of the Senses salon. Members and Biodesign...

Antimicrobial chemicals in indoor dust associated with higher count of antibiotic-resistance genes

September 7, 2016

In a collaborative study involving four major universities, researchers have found links between the levels of antimicrobial chemicals and antibiotic-resistance genes in the dust of an aging building used for athletics and academics.   The association was particularly striking for triclosan, the most commonly used antibacterial ingredient in personal care products. Whereas the study design investigated co-occurrence rather than causation, the study does point to a probable cause...

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...
