Details on results:
See category for PI, PAM and their salts.

The toxicity to soil macro organisms except arthropods was estimated by comparing with the measured toxicity (NOEC) for PI, PDPI and PPI versus the weight percentage of PAM in each of the substances:

weight%       NOEC (mg/l)
PI              0        >=1000
PDPI       46.5       >=1000
PPI          63.5       >=1000      
PAM       100       estimated

PI = 2-phenyl-2 -imidazoline, CAS 936-49 -2
PAM = benzene-1,2,4,5 -tetracarboxylic acid, CAS 89 -05 -4
PDPI = 1 mol PAM plus 2 mol PI, CAS 54553 -91 -2
PPI = 1 mol PAM plus 1 mol PI, CAS 54553 -90 -1
