News Center Maine: Maine scientist Graham Sherwood from the Gulf of Maine Research Institute says these results don't surprise him. “We typically associate highly urbanized waterways with contaminants anyway,” he explained.
So, should the drug discovery worry Mainers? Both scientists say not yet. “We think that this is a problem that's really restricted to urbanization in Puget Sound in the big cities,” Lanksbury explained. Both Lanksbury and Sherwood say mussels are good species to test for two reasons. One - they don't have a functioning liver, so they don't process drugs. Two - they stay put, so they're a good indicator of the water around them.
