干红中总酚含量与还原能力大致成正相关，表明干红的抗氧化能力与其所含有的总酚类物质有关。

The average concentrations of Cr, Cd and Pb in ectoskeleton, liver, and muscle were 4.03, 0.12 and 12.31 μgg^(-1), 3.88, 1.04 and 9.12 μgg^(-1), and 4.16, 0.09 and 0.72 μgg^(-1), respectively. Among the three test sites, there existed significant differences in the enrichment of Cr in ectoskeleton and muscle, and of Cr, Cd and Pb in liver. The enrichment of test heavy metals had no notable correlation with the body mass of P. clarkia, and no significant difference was found in the enrichment of the heavy metals between female and male individuals.
