Abstract: |
The column sedimente were sampled with the depths of 2 cm from surface Layer of foitr stations in trunk and two &tation$ in branches from the Baolou section of the Yellow River, and the heavy metals such as copper, plumbum, zinc and cadmium were measured in each layer. Diversity and evenness of the heavy metals' content in secondary phase, the potential ecological risk index and the sediment quality criteria were calculated by the Shannon-wiener
