Abstract

The objective of this study was to investigate the association between exposure to triaryl phosphate and monocyte nonspecific esterase staining activity in workers from a plant in Nitro, West Virginia. A cross-sectional study design was used to identify the exposed plant employees, and both a plant and a general population group. In addition to completing a questionnaire for each participant, 30 cc of blood were drawn and analyzed using four techniques, two morphological and two enzymatic. These procedures included a Technicon D-90 autoanalyzer, a Technicon H-6000 autoanalyzer, a manual enzymatic using alpha naphthyl butyrate, and a manual morphologic using Wright-Giesma stain. The results showed a decrease in nonspecific esterase staining with the Technicon D-90. No significant effect on monocyte numbers or esterase positivity was found with the other three techniques.
