Understood Dick.  In the case of this study, the top 6 insecticide residues
for toxicity were all involved in neural stimulation, either as NAChE
inhibitors, nAChRs, or sodium channel modulators.  The authors needed to
make some sort of assumption as to how to estimate the cumulative effect of
the exposures, and it seems to me that their assumption was not
unreasonable.
