Abstract:

The impact of a graphite dust on an aquatic ecosystem model, the Standard Aquatic microcosm SAM, was investigated. Graphite dust produced effects that resembled eutrophication in that a diversity decreased, ammonia increased, and a photosynthesisrespiration ratio of less than one was observed in the highest concentration. Compared to brass dust, graphite has much less potential to adversely impact aquatic ecosystems.
