Characterisation of trace elements and methylmercury in an estuarine sediment reference material, IAEA-405.
An estuarine sediment sample, IAEA-405, was recently characterised for trace elements and methylmercury (MeHg) for ultimate use as a marine reference material. The reference values were calculated using data sets from 120 laboratories that participated in a world-wide intercomparison exercise. The data evaluation is highlighted, and includes comparisons of different analytical methods, as well ...
متن کاملRevised delta34S reference values for IAEA sulfur isotope reference materials S-2 and S-3.
Revised delta(34)S reference values with associated expanded uncertainties (95% confidence interval (C.I.)) are presented for the sulfur isotope reference materials IAEA-S-2 (22.62 +/- 0.16 per thousand) and IAEA-S-3 (-32.49 +/- 0.16 per thousand). These revised values are determined using two relative-difference measurement techniques, gas source isotope ratio mass spectrometry (GIRMS) and dou...
متن کاملTracing Fine-Sediment Using Artificial Radionuclides
The environmental characteristics of many artificial gamma-emitting radionuclides provide a number of distinct advantages over other forms of fine-sediment tracer that are readily exploitable when undertaking erosion investigations. This makes them particularly effective for accurately measuring the movement of small quantities of fine-sediment, especially in low-energy environments where soil ...
متن کاملDetermining Total Mercury in Samples from the Persian Gulf and theCaspian Sea: Comparison of Dry Ash and Wet Extraction Mothods
Monitoring of mercury in environmental samples, with its proven toxicity on the food chain, requires sensitive and accurate analytical techniques. In this study, two methods for identification and quantification of total mercury in biological and sediment samples are compared: i) dry ash preparation and subsequent established procedures for Combustion Atomic Absorption Spectrometry, (AMA 254) ...
متن کاملReference Concentration for Shelf Sediment Transport Models
My long-term goals are to advance understanding of sediment transport processes. In this context, the long-term goal of this project is to advance understanding of the reference concentration, i.e. concentration of suspended sediments at a small distance above the seafloor. The scientific interest is in relating this reference concentration to the forcing conditions of waves and currents. The n...
