This report presents a Level I materials balance study of a group of anilines specified in a Task Order from the Office of Toxic Substances, U.S. Environmental Protection Agency. The compounds studied were aniline, aniline hydrochloride, aniline hydrobromide, o-, m-, and p-nitroanilines, 16 other nitroanilines, and 15 other chloro- and bromoanilines. Areas of major interest were production quantities, producers, consumption quantities, and emissions to air, land, and water related to these processes. The estimated amounts of 1978 production (where available) were as follows: aniline, 279,000 kkg; aniline hydrochloride, 4.6 - 100 kkg; o-nitroaniline, 3641 kkg; m-nitroaniline, 0 - 2.3 kkg; p-nitroaniline, 13,000 kkg. Emissions were estimated when direct data were unavailable. The results (in kkg/year) were: aniline, 20 kkg to air, 0.08 - 5.6 kkg to water; p-nitroaniline, 0.13 kkg to air, 117 kkg to water. Throughout the report, estimates and assumptions were made where justified, in lieu of direct data. Types of information required for future studies are noted.
