Toxicity and Fate of Nickel-Coated Graphite in a Marine Environment.
Abstract
The toxicity of nickel-coated graphite fibers was examined using the marine amphipod Ampellsca abdita. Fibers were mixed into the top 1 cm of sediment at concentration from 10 to 50 mg/L. The 10-day EC50 to amphipods was 40 mg/L. Fate studies (21 days) were conducted in salt water with and without sediment. Fate studies were also conducted with the fibers ground to powder. Ground fibers allowed a higher concentration of nickel to dissolve into the water column. However, when mixed into sediment, the concentration of dissolved nickel is significantly less.
