摘要: There are several advantages to the use of planktonic rotifers as freshwater bioassay organisms, yet few studies report toxicological data for these taxa. The goal present study was evaluate 24-h acute toxicity responses Brachionus calycifiorus six heavy metals, and compare metal tolerance this species published results other aquatic organisms. Metal B. calyciflorus, in decreasing order, Hg > Cu Cd Zn Fe Mn. This order follows theoretical ranking by affinity anionic radicals based on Lewis acid-base classification. While not quite sensitive Daphnia magna, calyciflorus is potentially useful a because it easy culture manipulate, widely distributed alkaline waters eastern North America.
