A water-extractable toxic compound in vinyl upholstery fabric.

A compound, highly toxic to goldfish, was found to be released from a vinyl (polyvinyl chloride) automotive upholstery fabric when the material was immersed in their water. The compound, a flame retardant used in such material, was identified by specific detector gas chromatography and mass spectrometry as triphenyl phosphate. Fish exposed to the immersed fabric or pure triphenyl phosphate showed neurologic intoxication and extensive histopathologic lesions.
