title: Genotoxicity of the coating lacquer on food cans, bisphenol A diglycidyl ether (BADGE), its hydrolysis products and a chlorohydrin of BADGE.
abstract: The epoxy resin bisphenol A diglycidyl ether (BADGE), its hydrolysis products and a chlorohydrin of BADGE (BADGE.2HCl), were examined for their genotoxicity in the micronucleus test (MNT) with human peripheral blood lymphocytes in vitro, in presence and in absence of an exogenous metabolizing system S9 rat liver. The treatment was done using different compound concentrations up to cytotoxic doses. The concentrations tested ranged between 12.5 to 62.5microg/ml of BADGE, 12.5 to 62.5microg/ml of first BADGE hydrolysis product (BADGE.H(2)O), 25.0 to 100.0microg/ml of second BADGE hydrolysis product (BADGE.2H(2)O) and 6.25 to 50.0microg/ml of BADGE.2HCl. These compounds are able to induce both cytotoxic and genotoxic effects, as revealed by the increases observed in cytokinesis block proliferation index (CBPI) and in micronuclei (MN) frequencies, respectively.
