Mammalian Toxicological Evaluation of TNT Wastewaters. Volume I. Chemistry Studies

Abstract
The objectives of this study were to identify the chemical components of two types of wastewaters discharged from Army munitions facilities and to supply quantitative data on each component. These data were used to establish representative ratios of the chemical components in the discharges. Data were obtained over 12-month sampling period to establish TNT/RDX ratios from Iowa and Milan Army Ammunition Plants and the relative percentages of more than 30 components in the condensate discharge at Volunteer Army Ammunition Plant. Analytical methods were developed to study the effects of sunlight on the discharges, and methods were developed to prepare photoirradiated residues under laboratory conditions for toxicity testing. Synthetic methods were developed to procure those wastewater components that were not commercially available, and analytical characterizations of all chemicals used in toxicity testing were obtained. Finally, preliminary estimates of the roles of volatility and photolysis in describing the environmental fate of condensate components in aqueous discharges were established. (Author)
