Includes bibliographical references (pages 18-21). "Histochemical techniques demonstrated the presence of the trace metals cadmium, copper, iron, lead and zinc within accumulation granules in various tissues of the bivalve Yoldia thraciaeformis. A higher density of granules was found within organisms obtained from Alice Arm, where the AMAX of Canada Ltd. molybdenum mine is located, compared to those from an adjacent inlet, Hastings Arm, and a reference station in Satellite Channel. In addition, granules were present in a greater number of tissue types and stained positively for more metals in Alice Arm Yoldia than in specimens from the other two sampling sites. Yoldia from both Alice Arm and Hastings Arm also appear to have enlarged kidneys compared to specimens from Satellite Channel, however, the small sample size in this study prohibits conclusions concerning a possible cause and effect relationship between metal sequestration and kidney enlargement. Metal granule density and granule distribution in organisms correlated well with sediment trace metal data in Alice Arm, Hastings Arm and Satellite Channel"--Abstract, page vi.
