enough to measure this predicted effect.

Anilines (Aromatic Amines):


For Fish Acute Toxicity Values: 2,3,5,6-Tetrachloroaniline is 19 times

more toxic than predicted by this SAR. Tetrabromoaniline may be more toxic

than predicted by this SAR as well.

For Daphnid and Green Algae Toxicity Values: Tetrachloro- and tetrabrom-

aniline may be 20 times toxic than predicted by this SAR.

N-Substituted anilines are less toxic than predicted by these SARs;

for these compounds, Neutral Organic SARs are used.
