A menace to mussels: Illicit drugs in waterways induce oxidative stress

Date: Jan 15, 2013

Author: Steve Down

The cocaine metabolite benzoylecgonine causes oxidative stress in freshwater mussels by inducing redox modifications in proteins, some of which are associated with glucose metabolism and cytoskeletal processes.
