We studied concentrations of trace elements such as iron, zinc, copper, lead and cadmium in three shorebird species from Saemankeum mudflat, Korea$(1999{sim}2000)$, and also analysed correlations between elements in livers. Iron(ANOVA, p=0.018), copper(ANOVA, p=0.043), lead(ANOVA, p=<0.001) and cadmium (ANOVA, p=0.016) concentrations significantly differed among shorebird species, but zinc concentrations wasn't different among species. We suggested that iron, zinc, and copper concentrations were within a range for normal and are maintained by normal homeostatic mechanisms for wild birds. Lead concentrations in Great Knots Calidris tenuirostris$(5.76{pm}2.14{mu}g/dry;g)$ were at the background level but Red-necked Stints Calidris ruficollis$(29.4{pm}10.6{mu}g/dry;g)$ and Terek Sandpipers Xenus sinereus$(15.9{pm}11.9{mu}g/dry;g)$ were within the exposed level for wild birds. In particular, Red-necked Stints were nearly poisoned level. Cadmium concentrations in Terek Sandpipers and Great Knots were at the background concentration, but Red-necked Stints were greater than the poisoned level$(3{mu}g/dry;g)$. We found significantly correlations between lead and cadmium concentrations, but other elements didn't find. |
