| This study focused on relationships between Pb and Cd concentrations and the difference of success reproductive progress in urban (Seoul) and industrial complex (Ansan) areas. Results of the Pb analysis for the feral pigeons from Seoul (egg contents:1.64 $mu extrm{g}$ wet $g^{-1}$, adults in bones: 29.5 $mu extrm{g}$ wet $g^{-1}$ and the Ansan industrial complex (egg contents: 1.13 $mu extrm{g}$ wet $g^{-1}$, adults in bones: 10.5 $mu extrm{g}$ wet g-1) showed that the Pb level of eggs and adults is significantly different between the two colonies (p<0.05). Cd concentrations in liver and kidneys of adult pigeons were also significantly different between Seoul(liver: 0.24 ${mu}g$ wet $g^{-1}$, kidney: 1.05 $mu extrm{g}$ wet $g^{-1}$ and the Ansan (liver: 0.14 $mu extrm{g}$ wet $g^{-1}$, kidney: 0.43 $mu extrm{g}$ wet $g^{-1}$ colonies (P<0.05). Clutch size of Feral Pigeons living in Seoul was similar between the two colonies, 1.9$pm$0.3 in Seoul and 2.0$pm$0.0 in Ansan. The length, breadth, and thickness of eggs were not significantly different between the two colonies (p>0.05). Incubation period in Seoul (17.8 days) did not differ from the Ansan (17.4 days). No difference in growth rate (body weight, wing length, and tarsus length) was found between the two test groups (p>0.05). In Seoul, 65.2% were hatching, and 42.1% fledging. The Proportion of hatching and fledging in the Ansan was 60.7% and 45.0%, respectively. The significant differences between the two colonies for reproductive sucess were not found (p>0.05). With regard to the reproductive effects to the heavy metals, the Pb and Cd concentrations feund in the two colonies were not as high as those considered in results of toxic effects in other species. |
