“…[11][12][13][14][15][16][17] However, radiocesium contamination in birds has only been sporadically reported. [18][19][20] In previous studies prior to the FDNPP accident, radiocesium contamination in birds was investigated around the Hanford Site, Savannah River Site, and Chernobyl Nuclear Power Plant; [21][22][23][24][25][26] however, birds are less frequently studied than fishes or mammals. Thus, investigating the radiocesium contamination in birds by the FDNPP accident is important to clarify the influence of radiation for birds.…”

Radiocesium concentrations in great cormorants (Phalacrocorax carbo) between 2011 and 2012 after the Fukushima Dai-ichi Nuclear Power Plant accident

Radiocesium concentrations were measured in the pectoralis muscles of great cormorant (n = 36) collected from Gunma Prefecture between November and July 2012. The 137 Cs contamination levels in great cormorant were consistent with the 137 Cs deposition levels on ground soil and 137 Cs concentrations of freshwater fishes. The Tag of great cormorants were comparable with those of other birds except for copper pheasant.

“…That is why they could be one of the constituent in radionuclides transport (Navarro et al 1998 ). Brisbin ( 1993 ) stated seabirds were probably not very useful in radionuclide monitoring because levels did not tend to increase food chains and the assimilation efficiency of most radionuclides through the digestive system of seabirds was poor. However, the knowledge on 241 Pu distribution is indispensable for the correct assessment of its radioactive contamination and the radiological consequences.…”

The paper presents unique data of plutonium 241Pu study in seabirds from northern Eurasia, permanently or temporally living at the southern Baltic Sea coast. Together, ten marine birds species were examined, as follows: three species that permanently reside at the southern Baltic, four species of wintering birds, and three species of migrating birds; 366 samples were analyzed. The obtained results indicated plutonium was non-uniformly distributed in organs and tissues of analyzed seabirds. The highest 241Pu content was found in the digestion organs and feathers, the lowest in muscles. Also, the internal radiation doses from 241Pu were evaluated.

“…There has been extensive research on patterns of radiocesium ( 137 Cs) contamination in tissues of animals from the SRS (Potter et al, 1989;Brisbin, 1993;Burger et al, 1997;Kennamer et al, 1998;Burger & Gibbons, 1998), but most heavy metals as well as selenium and arsenic have not been examined previously in the resident biota. This research was partially initiated to understand the exposure of wildlife residing in SRS to a suite of contaminants.…”

The relationship between metallothionein levels and concentrations of several metals and radionuclides was examined in liver tissues of raccoons (Procyon lotor, n = 47) from the Department of Energy's Savannah River Site in South Carolina to determine the applicability of metallothioneins as an initial screening device for exposure assessment in free-living mammals and environmental monitoring. Using a fluorescent marker and a cell sorter to measure metallothionein, a significant positive correlation was found across animals between levels of metallothioneins and concentrations of selenium (Pearson's r = .30), mercury (Pearson's r = .3 1), and copper (Pearson's r = .30) in liver tissue. Arsenic, cobalt, silver, thallium, and tin were below detection limits in most or all liver samples. Other metals, including cadmium, chromium, radiocesium (137-Cs), copper, lead, manganese, strontium, and vanadium, showed only weak and nonsignificant correlations with metallothionein. Concentrations of mercury were correlated with concentrations of selenium (Pearson's r = .73), manganese (Pearson's r = .56), and strontium (Pearson's r = .57). In an a posteriori test, there was a still unexplained positive correlation between mercury (Pearson r = .56), selenium (Pearson r = .54), and radiocesium (Pearson's r = .38) concentrations and background cellular autofluorescence, and a negative correlation of strontium with the latter (Kendall tau = -.38). Background cellular autofluorescence may represent a generalized cellular stress response, or a yet unidentified biomarker. To better understand which metals contribute to the induction of metallothionein, principle component analysis (PCA) was performed. The first three principle components explained 78% of the variance, with highest loadings being from mercury and radiocesium. Metallothionein levels did not correlate well with the principal components from the metals and radiocesium, while autofluorescent background levels tended to correlate better.
