Objective:

The objective of this research project is to examine the dietary uptake of metals via metal-contaminated sediment particles in invertebrates.

Progress Summary:

The initial phase of this study has used Daphnia magna to investigate dietary metal uptake from sediment particles. Because Daphnia are filter feeders, they sieve large quantities of water to collect suspended particles. Although their preferred food is algae, any suspended particles more than 0.45 µm will be retained on the filtering appendages and may be ingested. Sediments used in this study are collected from Clear Creek, Colorado. Clear Creek is a high-gradient stream, which receives metal-rich effluent from several mining sites, and has elevated metal levels in both the water and sediments. Because of the high concentration of easily mobilized metals associated with the sediments of Clear Creek, washing of particles is necessary to determine whether the dissolved fraction or the sediment was the main source of bioavailable metal. This work is designed to clearly define the role of particle-bound metal on the receptor organisms.
