the dose response ec50 values for the induction of aryl hydrocarbon hydroxylase ( ahh ) and ethoxyresorufin o-deethylase ( erod ) by the flame retardant pyrolysates was determined in rat hepatoma h-4-ii e cells and compared to the relative induction activities of 2,3,7,8-tetrachlorodibenzo-p-dioxin ( tcdd ) and the concentrations of `` '' 2,3,7,8-tcdd equivalents '' '' were calculated .
