Graphite fibers, nickel-graphite fibers, polycrystalline iron whiskers, and graphite Mirco-260 (M-260) were tested to determine their toxicities to Daphnia magna. The graphite fibers and nickel-graphite fibers were ground with a mortar and pestle before testing. The M-260 had an EC50 of 80.6 mg/L for four pooled replicates. None of the other compounds caused any deaths at concentrations up to 100 mg/L. All the bioassays were 48-hr acute studies. A 96-hr growth inhibition assay using Ankistrodesmus falcatus was performed with the graphite. No inhibition of A. falcatus was observed; however, the growth of the algae was enhanced by the two lowest test concentrations.
