The effects of mercury exposure on the surface morphology of gill filaments in Perna perna (Mollusca: Bivalvia)

Author: Gregory, MA ; George, RC ; Marshall, DJ ; Anandraj, A ; McClurg, TP Date: Jan 1999 This study investigated the possibility that changes in the surface morphology of mussel (Perna perna) gill filaments may be used to indicate the relative toxicity of pollutants in the marine environment. Healthy, adult P. perna were collected ... Read more
