April alumni trivia question:

Bioproducts and Biosystems Engineering Assistant Professor Abdennour Abbas and his lab team created a sponge that can absorb mercury from a polluted water source within less than 5 seconds for tap and lake water, and around 5 minutes for industrial wastewater. This could be an extremely important advancement for the state of Minnesota.

According to Minnesota's 2004 Impaired Waters List, what percentage of the waters in Minnesota are impaired due to mercury contamination (ranging from 0.27 to 12.43 ng/L )?

a) 17%
b) 37%
c) 67%
d) 87%

The answer: 67%, or about 2/3rds of the waters are impaired!
