(a) Venn diagram of the 2,408 tested chemicals. As reading example, 914 chemicals were tested only on fish, 867 chemicals were tested on fish and crustaceans, and 111 chemicals were tested on all taxonomic groups. (b) Overview of the number of chemicals tested (left) in the different combinations of taxonomic groups and the related number of data points (right), indicating that many tested chemicals do not automatically translate to many data points.
