Estimation of the Toxicity of Pollutants to Marine Phytoplanktonic and Zooplanktonic Organisms: Reference Methods For Marine Pollution Studies No. 44

This reference method describes procedures for estimating the toxicity of poisons to marine phytoplankton and zooplankton. Procedures are given for estimating the median effective concentrations (EC50) of poisons to phytoplankton, and the minimum algistatic concentration (MAC-5). For zooplankton, procedures are given for determining median lethal concentrations.
