Abstract
Naiads from two locations 11 river miles apart on the lower Muskingum River in Ohio were studied to determine whether location, calendar year and species could be correlated with the manganese concentration in the shells of the freshwater bivalve molluscs. Neutron activation analysis was used to determine the manganese concentration. The effect of each of these variables on the manganese content of the naiad shells was observed and discussed.
