Animals and Humans

The vanadium concentration in organs and in milk is not ho-
meostatically regulated. This is the case for all species investigated
(Table 9): grasshopper (160 mg/kg dry matter), carrion beetle
(212 mg/kg), spider (429 mg/kg), wood louse (1,674 mg/kg), slug
(449 mg/kg), edible snail (488 mg/kg), earth worm (5,450 mg/kg),
mice, voles and shrews (Sorex araneus, x = 254 mg/V, s = 127). The
vanadium concentrations of their bodies are fixed by the intake of
vanadium and vary extremely.
