Media Highlights
The surprising link between snow and pesticides
With the winter snowstorms that buried the East Coast, the snow itself has come under scrutiny. Children (and adults!) love to eat the white stuff, with some even using it in recipes. Snow looks beautiful and clean, but how safe is it? 

Dr. Staci Simonich suggests you might not want to eat the snow. Surprisingly, snow can carry pesticides, attracting the chemicals from the air and soil. 

On the plus side, the snow can help remove air pollutants. Dr. Simonich's research was featured on several news outlets, most notably on NPR and Chemical and Engineering News (C&En). 
A simple wristband is changing how we study environmental health. 
Dr. Kim Andersonwas featured in Chemical & Engineering News with the cover story. Her projects have been highly interdisciplinary and collaborative.

Pavement and PAHs 

Ever wondered what your driveway is made of? Turns out it is important to know! Dr. Staci Simonich studies polycyclic aromatic hydrocarbons present in sealcoats. Sealcoats are brushed on asphalt pavement to improve appearance and performance. The following news outlets picked up on the story: Science Daily, United Press International (UPI) and KGW8 (video). *This project was a collaboration with Project #3 and the Tanguay laboratory.

PNNL puts bacteria and bugs to work (Tri-City Herald)
"In an effort that builds on our earlier studies of the effects of low-dose radiation, scientists from PNNL and Oregon State University are assessing cancer risk from pollutants in diesel exhaust and cigarette smoke. They used computational techniques, in tandem with lab experiments, to more quickly analyze the immediate genetic response of skin cells of exposed mice and then employed statistics to determine the likelihood of those cells becoming cancerous."
