Abstract
This study investigated trace elements in the different organs of Eonycteris spelaea, a hill cave from the Bhuban Hills of Sonai Reserve Forest, Cachar, Assam (India). Six bats were collected from the site and concentrations of four trace elements (Cu, Zn, Fe, and Mn) were examined from the tissues of liver, lungs, kidney, and patagium using graphite furnace atomic absorption spectrometer (graphite furnace model-Analytic Jena Vario-6). The results of the study revealed that concentration of essential trace elements in the body tissues of E. spelaea were less than the maximum permissible limit. During the study, it was found that the concentration of copper in all the four organs are of the following order: liver (3 ± 0.11 μg/g dw) > lungs (2.4 ± 0.14 μg/g dw) > kidney (1.8 ± 0.10 μg/g dw) > patagium (1.8 ± 0.06 μg/g dw). For zinc, this sequence was kidney (61.8 ± 0.32 μg/g dw) > liver (61.2 ± 0.14 μg/g dw) > lungs (58.8 ± 0.19 μg/g dw) > patagium (46.8 ± 0.16 μg/g dw). For manganese, kidney (1.2 ± 0.15 μg/g dw) > lungs (0.6 ± 0.13 μg/g dw) > liver (0.6 ± 0.11 μg/g dw) > patagium (0.6 ± 0.10 μg/g), and for iron, it was liver (98.4 ± 0.22 μg/g) > lungs (78.6 ± 0.47 μg/g dw) > kidney (25.8 ± 0.23 μg/g dw) > patagium (16.2 ± 0.26 μg/g dw). Analysis of variance revealed significant differences (d.f. = 15, F = 44.84, P < 0.01) in the accumulation pattern in all the studied tissues of Eonycteris spelaea.
