Selenium Content in the Gonads of Healthy Cats () and Cats with Impaired Homeostasis from the Warsaw Area (Poland).

The aim of the present study was to evaluate selenium content in the gonads of healthy cats and those with impaired homeostasis with the use of fluorescence spectroscopy. Higher concentrations of selenium were found in the gonads of the male domestic cats studied. The average content of this element in the testes of healthy males was: 0.

The Total Mercury Concentration in Organs of Eurasian Magpies () and Common Woodpigeons () from the Warsaw Municipal Area.

Mercury is a toxic element widely distributed in the natural environment, affecting animals' health. It is released into the environment from both natural and anthropogenic sources. The present study analyzed the mercury concentrations in liver, kidney, heart and muscle tissue in two species of birds from the Warsaw area, which were used as bioindicators of local environmental pollution with this metal.

Relationship between Cd and Zn concentration in the kidneys, liver, and muscles of moose (Alces alces) from north-eastern Poland.

The aim of the study was to evaluate the cadmium and zinc content in the kidneys and liver of moose from north-eastern Poland. Animals were divided with respect to their age. The mean concentration of cadmium in the kidneys of moose studied was 11.

The Content of Copper and Molybdenum in the Liver, Kidneys, and Skeletal Muscles of Elk (Alces alces) from North-Eastern Poland.

The aim of the study was to evaluate the content of Cu and Mo in the liver, kidneys, and skeletal muscles of elks from north-eastern Poland. The investigation material comprised samples obtained in 2010 from 35 animals. Animals were grouped according to age (elks up to 2 years and over than 3 years).

The content of selected metals in muscles of the red deer (Cervus elaphus) from Poland.

The aim of this study was to evaluate the concentrations of Pb, Cu, Zn, Rb, Cs, Sr and Ba in the muscles of red deer that were hunted in two regions of Poland (south-western and north-eastern). The data obtained were evaluated with regards to benefits and potential risk to consumers' health. Samples for the investigations were collected in 2008 and 2009 from 50 female red deer, and the metal concentrations were determined by using the inductively coupled plasma-mass spectrometric (ICP-MS) method.

Magnesium concentrations in the tissues of free-ranging European bison.

The European bison (Bison bonasus) is the only living species of the bison genus in the Old World. It is the largest, wild, herbivorous mammal living in Europe. As a result of the efforts of biologists, the European bison has been saved as a species.
