The toxicity of nickel coated graphite was examined using Daphnia magna, the water flea 48 hr assay and Cyprinodon variegatus, the sheepshead minnow 96 hr assay. Daphnia were the most sensitive test organism having a 48 hr EC50 of 1.0 mgL soluble nickel. The sheepshead minnow showed no toxic signs up to 1000 mgL nickel fibers. Fate studies 21 days were conducted using various water hardness and salt water media. Daphnia magna, Sheepshead minnow, Environmental toxicity, EC50, Marine amphipods.
