Popis:	As part of an ongoing investigation of the transport, accumulation and excretion of metals in the infaunal eulamellibranch Mercenaria mercenaria (L.) organisms were exposed to radioactive cadmium followed by an autoradiographic study of the kidney tissue to determine the morphological sites of cadmium accumulation. Preliminary results of these studies indicate that cadmium is associated with large extracellular granules in the lumina of the kidneys. The presence of radioactive cadmium was determined morphometrically by counting developed silver grains on sections coated with a photographic emulsion. The results were statistically significant (99·9 % confidence—Student's t-test) to show that more radioactive cadmium was associated with large granules than with the background tissue.
