In order to increase the realism in the ecological risk assessment of chemicals, multispecies experiments are carried out. They have the advantage over laboratory single-species tests that they evaluate more realistic exposure regimes, assess effects on populations rather than individuals, allow the study of recovery of affected populations, and include food web interactions between populations. Alternative multispecies tests include a wide array of experimental designs, ranging from relatively simple indoor multispecies assemblages to model ecosystems and field monitoring studies. During the past decades, great progress in the development of such designs has been made.
