title: Study of mutagenicities of phthalic acid and terephthalic acid using in vitro and in vivo genotoxicity tests.
abstract: Genotoxicities of phthalic acid (PA) and terephthalic acid (TPA) were examined using three mutagenicity tests: Ames, chromosome aberration (CA), and micronucleus (MN). In the Ames test, these two agents did not produce any mutagenic responses in the absence or presence of S9 mix on the Salmonella typhimurium strains TA98, TA100, TA102, TA1535, or TA1537. The CA test also showed that PA and TPA exerted no significant cytogenetic effect on Chinese hamster ovary (CHO) cells. In the mouse MN test, no significant alteration in occurrence of micronucleated polychromatic erythrocytes was observed in ICR male mice ip administered any of these agents at doses of 0, 20, 100, 500, 2500 or 12,500 microM/kg. These results indicate that PA and TPA produced no mutagenic effects using these in vitro and in vivo mutagenic test systems.
