The inhibition ratio [(IA-[IA.sub.o])/NIA] was defined as the PA-inhibited arylesterase activity (IA) with p-nitrophenyl acetate as substrate minus the estimate of influence of nonspecific arylesterase activity of other carboxylic ester hydrolases ([IA.sub.o]) divided by the noninhibited arylesterase activity (NIA) with p-nitrophenylacetate alone as substrate (26).
The assays using p-nitrophenyl acetate as substrate had higher analytical variability than did paraoxon and PA assays.
Hydrolysis of p-nitrophenyl acetate (PNPA) to produce p-nitrophenol and acetic acid occurs readily.

P-Nitrophenyl acetate, N-S 130, trypsin, T-82253, chymotrypsin, C-3 142, and lysozyme, L-6876, were purchased from Sigma, St.
