✦ Synopsis
The transfer pathways of vanadium in Carcinus maenas (L.) were investigated from February to April 1978 in order to determine the role of the food and environmental medium in the accumulation of this metal. The crabs, purchased from a fish market in Nice, France, in February 1978, were contaminated by food (the polychaete Nereis diversicolor), by environmental medium, and by food plus medium. In the early stages (15 d) of contamination, the accumulation of vanadium was greatest in crabs exposed to the contaminated medium. In later stages (30 d) crabs exposed to contaminated food plus medium exhibited the highest accumulation. Very little accumulation was observed in crabs contaminated by food alone.
