Stable isotopes of carbon, hydrogen, nitrogen, oxygen and sulfur are widespread in nature.
Nevertheless, their relative abundance is not the same everywhere. This is due to kinetic …

The discovery of chemically induced mass-independent isotope fractionation in ozone
formation 40 years ago revealed a new type of isotope effect that was not considered within …

In carbon-compound-specific isotope analysis (carbon CSIA) of environmental
micropollutants, purification of samples is often required to guarantee accurate …

A method for estimating the ratio of stable carbon isotopes 13С/12С in the composition of
phthalates from surface water at a trace concentration level is proposed. It is based on the …

Subtle variations in stable isotope ratios at natural abundance are challenging to measure
but can yield critical insights into biological, physical, and geochemical processes. Well …

Abstract The 17 O-excess (Δ 17 O) of sulfate (SO 4 2−) in Antarctic ice cores is a potential
tool for assessing past oxidant chemistry. However, a significant gap between atmospheric …

Understanding the impact of human activities on the metabolic state of soil and aquatic
environments is of paramount importance to implement measures for maintaining ecosystem …

Retrospective information about the climate system and plant ecophysiology are key inputs
in climate and Earth system modelling. Dendrochronology provides such information with …
