USGS46a Greenland ice core water ? A reference material for stable hydrogen and oxygen isotopic composition of water
Ice core from Greenland was melted, filtered, and homogenized. Its stable hydrogen (δ2H) and oxygen (δ18O) isotopic compositions were adjusted to approximately match those of USGS46 ice core water (δ2H = ?235.8 ? and δ18O = ?29.80 ?). This isotopic reference water, USGS46a, was loaded into glass ampules, sealed, autoclaved to eliminate biological activity, and calibrated by dual-inlet isotope-rati
Chemical composition of leachates from hydraulic fracturing proppants from surficial releases in southeastern New Mexico
Resin-coated proppants (RCPs) are used in hydraulic fracturing of oil and gas wells to improve well performance; however, these proppants could be a cause for environmental concern if they are disposed of improperly. In this study, we investigate the water-leachable organic and inorganic constituents from proppants collected from surficial releases of RCPs in southeastern New Mexico. Significant c

Standard atomic weights of the elements 2021 (IUPAC Technical Report)
Following the reviews of atomic-weight determinations and other cognate data in 2015, 2017, 2019 and 2021, the IUPAC (International Union of Pure and Applied Chemistry) Commission on Isotopic Abundances and Atomic Weights (CIAAW) reports changes of standard atomic weights. The symbol A r°(E) was selected for standard atomic weight of an element to distinguish it from the atomic weight of an elemen

USGS44, a new high-purity calcium carbonate reference material for δ13C measurements
RationaleThe stable carbon isotopic (δ13C) reference material (RM) LSVEC Li2CO3 has been found to be unsuitable for δ13C standardization work because its δ13C value increases with exposure to atmospheric CO2. A new CaCO3 RM, USGS44, has been prepared to alleviate this situation.MethodsUSGS44 was prepared from 8 kg of Merck high-purity CaCO3. Two sets of δ13C values of USGS44 were determined. The f

Variation of lead isotopic composition and atomic weight in terrestrial materials (IUPAC Technical Report)
The isotopic composition and atomic weight of lead are variable in terrestrial materials because its three heaviest stable isotopes are stable end-products of the radioactive decay of uranium (238U to 206Pb; 235U to 207Pb) and thorium (232Th to 208Pb). The lightest stable isotope, 204Pb, is primordial. These variations in isotope ratios and atomic weights provide useful information in many areas o

IUPAC Periodic Table of the Elements and Isotopes (IPTEI) for the education community (IUPAC Technical Report)
The IUPAC (International Union of Pure and Applied Chemistry) Periodic Table of the Elements and Isotopes (IPTEI) was created to familiarize students, teachers, and non-professionals with the existence and importance of isotopes of the chemical elements. The IPTEI is modeled on the familiar Periodic Table of the Chemical Elements. The IPTEI is intended to hang on the walls of chemistry laboratorie
