摘要：

Laboratory studies of copper uptake by the midge larvae Chironomus tentans indicated that chemical speciation is an important consideration. Copper was taken up from solutions in which the dominant aqueous forms were free cupric ion and a copper hydroxy complex. No uptake was observed when copper-glycine and copper-NTA were dominant. Studies conducted with freshly killed larvae suggest that a relatively large portion of the copper taken up is due to nonbiological processes. © 1979, American Chemical Society. All rights reserved.
