Factors affecting trace element uptake in the black mussel Septifer virgatus
The variability of the influx rates of Cd, Cr(VI), Se(IV), and Zn in the black mussel Septifer virgatus from Hong Kong coastal waters was examined under different environmental and biological conditions using the radiotracer technique. The uptake of trace elements generaiiy proceeded linearly over time and a short-term exposure (4 h) was therefore employed to measure the influx rate of trace el...
متن کاملThe effect of tissue structure and soil chemistry on trace element uptake in fossils
Trace element profiles for common divalent cations (Sr, Zn, Ba), rare-earth elements (REE), Y, U, and Th were measured in fossil bones and teeth from the c. 25 ka Merrell locality, Montana, USA, by using laser-ablation ICP-MS. Multiple traverses in teeth were transformed into 2-D trace element maps for visualizing structural influences on trace element uptake. Trace element compositions of diff...
متن کاملPlanktonic-based assessment of the landside-dammed lake (Erzurum-Turkey)
The aim of this study was to identify the variation of plankton communities in the Tortum Lake. Changes in phytoplankton and zooplankton communities in relation to the abiotic environment were analyzed using multivariate analysis. Water samples were taken monthly from three sampling points of the Tortum Lake between June 2012 and May 2013. Water temperature (5.28-23.05°C), dissolved oxygen (1.5...

متن کاملTrace element diffusivities in bone rule out simple diffusive uptake during fossilization but explain in vivo uptake and release.
Diffusion rates of numerous trace elements in bone at 20 °C were determined using laser-ablation inductively coupled plasma mass spectrometry analysis of experimentally induced diffusion profiles. Diffusivities are about 1 order of magnitude slower than current semiquantitative geochemical views and about 1.5 orders of magnitude faster than indirect radiotracer estimates. Intrabone volume diffu...
