Additional information

The Yokohoma Laboratories study is highly detailed and was given a reliability of one because of compliance with GLP and inclusion of certificate. Results of the study include a selection of EC50 and NOEC values based both on "growth rate" and "area under the growth curve". However it should be noted that results elsewhere confirm that for 4,4'-MDA algae are not the most sensitive species of the three trophic levels of the base-set (fish, daphnia and algae).
