A series of hydroxyapatite pellets were produced to use as matrix-matched standards for LA-ICP-MS analysis of trace metals in the first dorsal spine of tuna fish species (albacore tuna, Thunnus alalunga, and Atlantic bluefin tuna, Thunnus thynnus). These structures are interesting because they ...
Laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) is a widely accepted method for direct sampling of solid materials for trace elemental analysis. The number of reported applications is high and the application range is broad; besides geochemistry, LA-ICP-MS is mostly used ...
These samples were then identified and by gas chromatography mass spectrometry (GC/MS). The obtained mass has also been recorded for different functional groups by FTIR. They found organic compounds are saturated and unsaturated hydrocarbons, aromatic alcohols, phenols and dicarboxylic acids which ...
In addition, precipitation of calcium phosphates was observed upon interaction between chrysotile asbestos and simulated lung fluids, and SEM analyses of calcified pleural plaques detected the presence of hydroxyapatite secondary phases in lung tissues (Taunton et al., 2010). The aim of the present ...
The ICP-MS studies revealed that certain elements had moved from dental cavity fillings to the healthy area of the teeth. These analyses reveal high/low element concentrations inside the tooth matrix, allowing monitoring of mineralization of the hydroxyapatite matrix and element migration, as well as...
Scanning electron microscope and transmission electron microscopy studies reveal that bioapatite fossils mainly consist of aligned hydroxyapatite nano-plates. Laser ablation-inductively coupled plasma-mass spectrometry analyses show that the REY are not uniformly distributed within the studied bioapatite fossils...
However, making accurate measurements of 87Sr/86Sr inbio-apatites by LA-MC-ICPMS is an extremely challenging analysis which is beset by a complexseries of interferences on the isotopes of interest.Interference species are numerous but come principally from the gases used to generate the plasma...
In contrast to the contamination of the embedding sediment, no general increase in heavy metal concentrations in fish scales was observed down to the cores. It is inferred that the rapid sorption stabilizes the biologic hydroxyapatite of the fish scales, which thus rapidly attain a thermodynamic ...
The principal aim of this study was to compare several calibration strategies for determining Mn content in tooth and bone by LA-ICP-MS including: (a) a six-point calibration curve based on synthesized hydroxyapatite (HA) materials, and single-point calibrations based on (b) NIST SRM 1400 ...
