Moose and heavy metals
Moose in southern Norway are in significantly worse health than those further north and in eastern Norway. An analysis of roughly 600 moose livers, combined with information such as carcass weights and ages, shows that Norway’s southernmost herds are afflicted with kidney problems and osteoporosis.
Marit Nordløkken, a PhD candidate in NTNU’s Department of Chemistry, is investigating whether one of the factors behind these findings may be high concentrations of heavy metals.
Cadmium accumulation
Nordløkken’s analysis shows that there is enough cadmium in the moose organs from southern Norway that hunters should think twice before they eat large amounts of foods made with moose liver or kidneys, such as liver pate or kidney pie.
“Many heavy metals are stored in the liver and kidneys of animals and humans alike. I have found a great deal of cadmium in my analysis. Cadmium is not acutely toxic, but the amount in the body increases with age and can eventually cause health problems and disease,” Nordløkken says.
