Raspodjela 137Cs u mesu i unutarnjim organima divlje svinje

Wild boar (Sus scrofa) is one of the most common species of game on the territory of Croatia. Similarly to other game, it can accumulate fission products more effectively than domestic animals. Therefore, it is a good biondicator for radioactive contamination of ecosystems. The purpose of our research has been to investigate current radioactive contamination of wild boars by 137Cs and its distribution inside the animal body. Therefore, during the winter of 2009 and summer of 2010, we collected samples of meat, internal organs (heart, lungs, spleen, kidney and liver) and bones from 11 animals. All the animals were from the area of the research locality „Šumbar“. The average activity concentration of 137Cs found in meat samples was (1, 47±0, 01) Bqkg-1, and in bones (0, 12±0, 01) Bqkg-1. Activity concentration found in organs was (in ascending order): lungs (1, 63±0, 01) Bqkg-1, spleen (2, 29±0, 04) Bqkg-1, liver (2, 54±0, 02) Bqkg-1, heart (2, 70±0, 02) Bqkg-1, and kidney (3, 18±0, 06) Bqkg-1. We also calculated the values of the ratio of activity concentrations in internal organs and meat. Comparison of the obtained values with those for samples collected after the Chernobyl accident shows that the present ones are higher for liver and kidney, while those for heart are almost the same. Since vital organs of wild boars are more loaded than meat and bones, the impact of radioactive contamination on health of these animals should be more closely investigated. Also, these results imply that kidney is the most accumulating organ for 137Cs.
