Evaluation of the Aquatic Toxicity and Fate of Brass Dust Using the Standard Aquatic Microcosm

摘要

The impact of brass dust on a model aquatic ecosystem, the Standard Aquatic Microcosm (SAM), was investigated. Brass dust had dramatic effects on the interaction of trophic levels, community structure, and metabolism of nutrients. Copper was rapidly released from the dust material suspended in the water column. Brass dust has the potential to severely impact aquatic ecosystems.
