With regard to acute toxicity, the cubosols are attributed to the non-cumulative compounds of low toxicity. Acute inhalation exposure threshold for cubosol "Bright green" is over 140 mg/m3. Subacute poisonings developed following intragastric administrations in concentrations 1 g/kg for 30 days, and were characterized by polymorphism of the signs. Revealed were delayed body mass increment in the laboratory animals, changes in peripheral blood and hepatorenal morphology and function.

[Mutagenic activity of the azo dye Disperse Orange 2K and its basic component Reax dispenser]. / Mutagennaia aktivnost' azokrasitelia dispersnogo oranzhevogo 2K i ego osnovnogo komponenta dispergatora reaksa.

Mutagenic activity of inhaled dispersed orange 2K nitrodye (DON 2K) and Reax' disperser was evaluated. Chronically inhaled DON 2K (with disperser) in concentration 28.6 mg/m3 is a genetic danger for an individual and population, being also a selective by injurious++ to the red blood cells. Chronically inhaled Reax' disperser (25.7 and 5.8 mg/m3) shows low mutagenic activity in somatic tissue. Thus, the mutagenic effect of DON 2K with disperser (composition is constant) is explained by nitrodye and not a disperser.
