Photodegradation of strong copper-complexing ligands in organic-rich estuarine waters
Exposure to solar radiation substantially decreased the strong copper-complexing capacity of samples collected from the organic-rich Cape Fear estuary, North Carolina. Samples exposed to natural sunlight for 1–2 d experienced a loss of strong Cu ligand (modeled at fixed K9CuL 5 1013.5) ranging from 15–33%, and .90% using long-term exposures under controlled conditions with a Xe arc solar simula...
متن کاملBenthic fluxes of copper, complexing ligands and thiol compounds in shallow lagoon waters.
Benthic fluxes of copper, copper complexing ligands and thiol compounds in the shallow waters of Venice Lagoon (Italy) were determined using benthic chambers and compared to porewater concentrations to confirm their origin. Benthic copper fluxes were small due to small concentration differences between the porewaters and the overlying water, and the equilibrium concentration was the same at bot...
متن کاملForaminifera: distribution of provinces in the Western north atlantic.
All published distributional data on recent benthic foraminifera of the North American Atlantic continental margin were archived into computerized catalogs. Cluster analysis of these data delimited seven large, marginally overlapping provinces exhibiting a congruous relationship with western North Atlantic water masses. The single major latitudinal faunal change occurs at Cape Hatteras.
متن کاملFluxes of copper-complexing ligands from estuarine sediments
Most studies of the organic complexation of Cu in natural waters have focused on distributions and processes in the water column, where a significant fraction of Cu-complexing ligands may be biologically produced. We present direct evidence for a flux of Cu-complexing ligands from estuarine sediments, demonstrating that sediments are a significant, yet previously unrecognized source of the liga...
