摘要: The research is designed to explore the SEM-AVS concept as a tool assess bioavailability and toxicity of heavy metals in heavily polluted river sediments. value AVS SEM high level only few benthic invertebrate are found. Abundance has significant correlation with SEM/AVS (r = −0.913, p < 0.01) −0.725, 0.05). analytical results MDS (Non-matric Multi-dimentional Scaling) analysis indicate community structures seven among nine stations where ∑SEM5-AVS 0 similar. two facts also useful
