Magnitude of Acute Toxicity of Marine Sediments Amended with Conventional Copper and Nanocopper

摘要

It is well known that copper (Cu) is toxic to marine organisms. We measured and compared the acute toxicity of several forms of Cu (including nanoCu) amended into a marine sediment with mysids and amphipods. For all the forms of Cu tested, toxicity, measured as the median lethal concentration, ranged from 708 to 2400mg Cu/kg (dry sediment) for mysids and 258 to 1070mg Cu/kg (dry sediment) for amphipods.
