Description:
The report gives results of an evaluation of toxicities of dyebath discharges from atmospheric dyeing of polyester fiber/fabric with three commercial dye carriers: trichlorobenzine (TCB), biphenyl (BP), and 0-phenyl phenol (OPP). First, criteria were established to rank the priority of all commercial dye carriers, based on known toxicities and volumes of consumption. Biological testing and chemical analyses were carried out on the discharges of these dyebath systems. Bioassays included: (1) Ames Salmonella/microsome mutagenesis assay, (2) acute in-vivo mouse quantal assay, and (3) aquatic ecological assay with Daphnia magna. Analytical procedures were established for both qualitative identification and quantitative determination of key dyebath components.
