Cyst-based Toxicity Tests. IV. The Potential of Ecotoxicological Tests for the Prediction of Acute Toxicity in Man as evaluated on the first ten Chemicals of the MEIC Programme.... In the framework of the multicentre evaluation of in vitro cytotoxicity(MEIC) programme, the first ten chemicals of the prescribed list were tested for acute toxicity in four standardized cyst-based aquatic invertebrate tests, consisting of two rotifer species(the estuarine Brachionus plicatilis and the freshwater Brachionus calyciflorus) and two crustacean species(the halophilic anostracan Artemia salina and the freshwater anostracan Streptocephalus proboscideus). 1, record 1, English, - cyst%2Dbased%20toxicity%20test

El rotífero es un animal aerobio, heterótrofo y multicelular. Su nombre procede del hecho de que tienen dos juegos de pestañas giratorias sobre la cabeza que utilizan para su alimento y captura de alimentos. Los rotíferos son muy eficaces al consumir bacterias dispersas y floculadas, así como pequeñas partículas de materia orgánica. Su presencia en un efluente indica un proceso aerobio de purificación biológica muy eficiente. 1, record 2, Spanish, - rot%C3%ADfero
