Characterization of heavy metal contamination in the habitat of red-crowned crane (Grus japonensis) in Zhalong Wetland, northeastern China.

Abstract

Heavy metal enrichment in the prey of red-crowned cranes in Zhalong Wetland, northeastern China was researched. Lead and Cd were the most abundant elements in the sediments; their concentrations ranged from 9.85 to 127 ppm and from 1.23 to 10.6 ppm, respectively. Six aquatic animal taxa contained detectable levels of heavy metals, in the decreasing order of… (More)
