| Concentrations of Fe, Zn, Mn, Cd and Pb were determined in the tissues of sixty adult pigeons collected at six colonies in Korea, and examined correlations between elements, and between tissues in feral pigeons. As the results, we found many significant correlations between elements, and between tissues in them, A negative correlation between Cd and Fe concentrations was observed in the kidney, Cd depresses the absorption of Fe from the intestine and, in this way, affects the levels of Fe in particular tissues. This tendency could be expressed in terms of lower hemoglobin and hematocrit values because hematocrit is one of the most sensitive indicators of Cd intoxication. Zn concentrations are strongly associated with higher Cd levels in the kidney and liver. This is thought to be a reflection of the interaction known to occur between these two metals. Zn induction has been shown to antagonize a number of toxic effects of Cd. A positive correlation between Pb and Fe concentrations was detected in the livers at the Busan colony with relatively high Pb and Fe concentrations. Pb has been shown to co-accumulate with Fe in the liver by inhibiting the heme synthesis. Significant correlations, especially in toxic elements, Pb and Cd, were observed for many pairs of tissues. We suggest that these correlations between elements, and between tissues should be considered in biomonitoring for heavy metal pollution. |
