It is described a utility model of containment device for test of ecotoxicity in situ in the aquatic environment.Allowing the methodological standardization and applicability to aquatic ecosystems (lu00eanticos and lotic) and various groups of animals.Having a format hexau00e9drico (10) which allows the anchoring of the bases on any surface, in addition to the more direct contact with sediment and / or contaminant.As well as presenting a locking prevents escape of the organisms and the commitment of the tests test any storm.
