Relative Importance of Food and Water in Long-Term Zinc−65 Accumulation by Marine Biota
Shrimp, crabs, and fish were maintained for 3 mo in a 65Zn-labeled simulated ecosystem in which individuals were allowed to accumulate the radiotracer either directly from the water or from aExpand

Factors affecting methyl and inorganic mercury dynamics in mussels and shrimp
Radiotracer experiments were designed to study the effect of certain factors on the accumulation and loss of methyl and inorganic mercury in mussels (Mytilus galloprovincialis) and benthic shrimpExpand

Vertical transport of particulate-associated plutonium and americium in the upper water column of the Northeast Pacific
Concentrations of plutonium (Pu) and americium (Am) were determined in seawater, suspended particulate matter, sediment trap samples, and biogenic material collected at the VERTEX I site in the NorthExpand

Assimilation, inter-organ transfer and excretion of americium in two teleost fish
Radiotracer experiments were performed (February–April, 1982) to study the assimilation and metabolism of the transuranium nuclide americium-241 in the marine teleosts Serranus scriba (Linnaeus,Expand

The vertical flux of rare earth elements in the northwestern Mediterranean
Rare earth element (REE) composition of sinking particles was examined in time-series sediment trap samples collected from four depths (200, 500, 1000, 2000 m) in the Gulf of Lions. Vertical fluxExpand

Interannual Variation in Transuranic Flux at the Vertex Time-Series Station in the Northeast Pacific and Its Relationship to Biological Activity
From October 1986 through May 1988, seven cruises took place at approximately three-month intervals at the VERTEX time-series station (33°N, 139°W) in the North Pacific. Data on plutonium (239+240Pu)Expand
