The discovery of the first chemically produced mass-independent isotope effect in 1983 by
Thiemens & Heidenreich opened a broad variety of applications, including physical …

Abstract Perchlorate (ClO 4−) is a strong oxidizer and has gained significant attention due to
its reactivity, occurrence, and persistence in surface water, groundwater, soil and food …

There remains a lack of understanding of environmental isotopes and their use; students
and practitioners typically find the concepts of isotope concentrations and partitioning to be …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

The Wet Chemistry Laboratory on the Phoenix Mars Lander performed aqueous chemical
analyses of martian soil from the polygon-patterned northern plains of the Vastitas Borealis …

Perchlorate, an iodide uptake inhibitor, is increasingly being detected in new places and
new matrices. Perchlorate contamination has been attributed largely to the manufacture and …

Isotopic studies indicate that natural perchlorate is produced on Earth in arid environments
by the oxidation of chlorine species through pathways involving ozone or its photochemical …

Abstract Perchlorate (ClO 4−) is a persistent water soluble oxyanion of growing
environmental interest. Perchlorate contamination can be a health concern due to its ability …

In the past few years, it has become increasingly apparent that perchlorate (ClO4−) is
present on all continents, except the polar regions where it had not yet been assessed, and …

In extremely arid regions on Earth, such as the Atacama Desert, nitrate, sulfate and
perchlorate salts form in the atmosphere and accumulate on the surface from dry deposition …
