[The experimental transplacental passage of dimethylformamide and toluene].

The author presents data on the transplacental passage of dimethylformamide (DMFA) and toluene in combined exposure at the level of the maximum allowable concentrations. A new method for measurements of chemicals in animal biomedia is suggested. The permeability index for DMFA has made up 37.1%, that for toluene 90.2%. The results recommend the new method for experimental and clinical measurements of chemicals.
