OECD GUIDELINE FOR THE TESTING OF CHEMICALS

The recommended subchronic toxicity value is set at the subchronic value from which the chronic value is derived. (The IRIS chronic RfD for cyanide incorporates an uncertainty factor 10 for subchronic-to-chronic extrapolation. The IRIS chronic RfC incorporates an uncertainty factor of 100.5 for subchronic-to-chronic extrapolation) ................
