Chemical analysis and toxic tests were combined with benthic macro invertebrates community structure alternations. Based on tri-axial graphs together with relevant matrix of decision-making, the initial bio-responsive sediment quality criteria clearly indicated the situation of heavy metal pollution, and showed the dose-response relationships between heavy metal contamination and benthic biotics. Moreover, the SQC may provide some basic material for establishment of sediment quality standards and for follow-up remediation engineering in the area.
