Isotope Ratio Measurements for Sample Dating Studies Using Multicollector ICP-MS and Signal Enhancement via a Desolvating Nebulizer Accessory with Nitrogen Gas Addition
Multicollector ICP-MS instruments are widely used in geochemistry for high precision isotope ratio measurements. Isotope signal enhancement and/or mass spectral interference reduction (ex. oxides and hydrides from any injected water) is often necessary for useful measurement of low abundant isotopes and mass-limited samples. This work will describe the setup, optimization, and use of an advanced ...

Reanalysis of uranium toxicity data for selected freshwater organisms and the influence of dissolved organic carbon
The present study re‐analyzed 46 existing uranium (U) chronic toxicity datasets for four freshwater species to generate consistent toxicity measures and explore relationships between U toxicity and key physicochemical variables. Dissolved organic carbon (DOC) was consistently the best predictor of U toxicity based on 10% inhibitory concentration (IC10) and median inhibitory concentration (IC50) ...
