摘要

以詹姆斯河河口泥沙和水体为研究对象,评价了泥沙浓度(20%、5%、2.5%和1%)、混合时间(120、30和5 min)和底泥中Kepone浓度(0.04和0.02 mg kg - 1)对试验结果的影响。方差的析因分析表明,在上述参数范围内,沉积物中的酮浓度是控制洗脱水中浓度的唯一因素。该结果与在收集沉淀物进行洗脱试验的地点附近进行的疏浚作业中采集的样品的分析结果一致。Kepone洗脱结果表明,相对较低的沉积物浓度(1%)足以获得有意义的洗脱结果。这表明标准的洗脱液测试(环境保护局,1973年)可能会规定过量的沉淀物(20%),这可能会给分析人员带来不必要的负担。

Evaluation of elutriate test parameters for an organic hydrophobic pollutant, Kepone

The following elutriate test parameters were evaluated using sediment and water from the James River estuary to determine their effects on test results: sediment concentration (20, 5, 2·5 and 1%), mixing time (120, 30 and 5 min) and Kepone concentration in/on the sediment (0·04 and 0·02 mg kg−1). A factorial analysis of variance indicates that Kepone concentration on sediment is the only factor within the above parametric ranges controlling concentrations in the elutriate water. The results agree with analyses of samples taken during a dredging operation near the site of sediment collection for the elutriate tests.

The Kepone elutriate results indicate that a relatively low sediment concentration (1%) is adequate to obtain meaningful elutriate results. This suggests that the standard elutriate test (Environmental Protection Agency, 1973) may prescribe an excessive amount of sediment (20%) which may impart an unnecessary burden on the analyst.
