The developmental toxicity of xylene and xylene isomers in the Hydra assay.
Two laboratories tested multiple forms of xylene for their developmental toxicity hazard potential (A/D ratio) by means of the hydra assay. The three isomers, as well as a solution of mixed xylenes, all interfered with development (D) at or near to concentrations that also were toxic to adult (A) hydra. ⋯ In each instance every xylene tested interfered with the same stage or developmental sequence and in a concentration-related manner. The hydra assay may be useful for establishing priorities to test agents in a more elaborate system, but substances less soluble than xylene may exceed the test's applicability.
