    The study was performed to assess the concentrations of heavy metals: cadmium (Cd) and lead (Pb) as well as essential elements: copper (Cu), zinc (Zn) and molybdenum (Mo) in the spleen of moose from Northeastern Poland. The animals studied were divided into two age groups (juvenile individuals up to 2 years old and mature animals older than 2 years).The concentrations of selected elements in the collected samples was determined by the inductively coupled plasma mass spectrometry (ICP-MS). The mean concentrations in the organs examined were: 2.28, 0.10, 8.36, 25.29 and 0.22 mg ∙ kg–1 wet weight, respectively for cadmium, lead, copper, zinc and molybdenum. Although higher values were found in older individuals, both age groups did not differ statistically. In the analysis of relations between selected metals we noted statistically significant correlations between following pairs of elements: zinc and molybdenum (r = 0.58), cadmium and copper (r = 0.56) and cadmium and molybdenum (r = 0.55). The cadmium, lead, copper, zinc, and molybdenum levels in the moose spleen was higher in the group of the older individuals than in the younger ones. Although there are no reference values for the cadmium and lead concentrations in the moose spleen the mean values observed can be considered high because they correspond to the levelsbregistered in the organs of other ruminant species living in the industrial regions. This phenomenon is due to the presence of a few older individuals with high levels of those metals in the spleen among investigated animals.
