本研究的目的是评估三个生物测定代表多个营养水平的适用性，从采矿活动污染的网站的沉积物的初步生态毒理学筛选。在这项研究中使用的生物测定，介形虫测试是最敏感的。费氏弧菌发光抑制试验对沉积物中有毒物质的敏感性低于植物毒性试验。观察到的总趋势是，随着沉积物样品中金属流动的增加，生物测定测得的毒性值也增加。因此，该组合可作为一种快速、灵敏的评价沉积物中重金属污染的工具。
The aim of this study was to evaluate the applicability of three bioassays representing multiple trophic levels, for the preliminary ecotoxicological screening of sediments from sites contaminated by mining activities. Of the bioassays used in this study, the ostracod test was the most responsive. Vibrio fischeri luminiscence inhibition assay was less sensitive to the toxicants in the sediments than the phytotoxicity assays. The general trend observed was an increase in toxicity values measured by the bioassays with increasing metal mobilization in sediment samples. Therefore, the test battery can be used as a rapid and sensitive tool to evaluate the heavy metal contamination in sediments.
