Smokes dyes are used by military personnel for signalling and marking purposes. Because dissemination of smoke dyes results in deposition on vegetation, soil and surface waters there is a need to determine their potential environmental impact. The present study was designed to provide part of the data necessary for environmental assessment. The project consisted of seven tasks addressing three basic goals 1 purification and characterization of study compounds, 2 measurement of reaction rates and identification of products for the most probable transformation products as typified by the anilines. Five pathways or processes were identified that were expected to be important for the environmental fate of the smoke dyes 1 partitioning from water to soil sediment and biota, Tasks 2, 3, and 4, 2 assessment of metal complexation Task 5, 3 photolysis on soil Task 6, 4 transformation in anaerobic sediments Task 7, and 5 transformation of aeromatic amines Task 8.
