In response to a request from an authorized representative of employees at the Exxon Corporation (SIC-2911), Baton Rouge, Louisiana, an investigation was begun into a possible reproductive health hazard at the refinery waste water treatment facility. The refinery processed crude petroleum into a variety of products, processing about 500,000 barrels of crude oil each day. The men had noted what seemed to be an excessive number of spontaneous abortions occurring among their wives. A cross sectional evaluation of sperm concentration and sperm morphology was conducted in wastewater treatment facility workers and two control groups (those who worked in other portions of the refinery and administrative personnel who did not work in the refinery itself). Of the 68 men employed in the wastewater treatment facility during the 6 month period before this study, six were not eligible for the study. Semen samples were provided by 42 of the 62 eligible men, and by 73 control subjects. After data adjustment for abstinence period, the mean sperm concentration of the unexposed group did not differ significantly from that of the 42 exposed men. The two groups also had a similar proportion of sperm with abnormal morphology. Controlling for other factors did not alter these findings. The authors conclude that no significant effect on sperm concentration or morphology was found to be associated with work at the wastewater facility.
