Principles and Treatment Methods for Metal Isotopes Analysis
Yankuang ceshi, 2021 BACKGROUND In the past twenty years, methods for metal isotopes analysis (iron, copper, zinc, magnesium, calcium, lithium, molybdenum, selenium, mercury, chromium, cadmium, alum, barium, titanium, etc.) have been established.

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

High-density element concentrations in fish from subtidal to hadal zones of the Pacific Ocean
Heliyon, 2018 Anthropogenic use of high density, toxic elements results in marine pollution which is bio-accumulating throughout marine food webs. While there have been several studies in various locations analyzing such elements in fish, few have investigated ...

Chromium isotopes as indicators of hexavalent chromium reduction [PDF]
, 2012 This is the final report for a university research project which advanced development of a new technology for identifying chemical reduction of hexavalent chromium contamination in groundwater systems. Reduction renders mobile and toxic hexavalent chromium immobile and less toxic.

The chromium isotopic composition of Almahata Sitta [PDF]
Meteoritics & Planetary Science, 2010 Abstract– Nine ureilitic fragments of the anomalous polymict ureilite Almahata Sitta have been analyzed for their Cr isotopic compositions. All the samples, including both nonmagnetic and magnetic portions, show essentially the same ε54Cr deficit (−0.77 ± 0.10), relative to the terrestrial Cr standard.
