Table 2 Levels of physiological blood parameters, and effects of environmental radiation category on adult breeding Eastern tree frog (Hyla orientalis) males collected in areas of medium-high radiation (CEZ-High, n = 35), and low radiation (CEZ-Low, n = 30) within the Chernobyl Exclusion Zone, and areas outside the Chernobyl Exclusion Zone (Outside CEZ, n = 14). Blood parameters were: sodium (Na), potassium (K), chloride (Cl), ionized calcium (iCa), total carbon dioxide (TCO2) and anion gap (AnGap), all in mmol/L; and glucose (Glu), and urea nitrogen (BUN), both in mg/dL. Physiological values are presented as least square means ± SE, including the range of values, and sample size for each category
