Hydrogen isotopes are unique tools for identifying and understanding biological and
chemical processes. Hydrogen isotope labelling allows for the traceless and direct …

Abstract Groundwater 18O/16O, 2H/1H, 13C/12C, 3H, and 14C data can help quantify
molecular movements and chemical reactions governing groundwater recharge, quality …

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 …

Due to human activities to a greater extent and natural processes to some extent, a large
number of organic chemical substances such as petroleum hydrocarbons, halogenated and …

Polycyclic aromatic hydrocarbons (PAHs) are widespread in marine ecosystems and
originate from natural sources and anthropogenic activities. PAHs enter the marine …

Gas chromatography–isotope ratio mass spectrometry (GC-IRMS) has made it possible to
analyze natural stable isotope ratios (eg, 13C/12C, 15N/14N, 2H/1H) of individual organic …

Measuring stable isotope fractionation of carbon, hydrogen, and other elements by
Compound Specific Isotope Analysis (CSIA) is a new, innovative approach to assess …

Compound-specific stable-isotope analysis (CSIA) has greatly facilitated assessment of
sources and transformation processes of organic pollutants. Multielement isotope analysis is …

Physical, chemical and biological processes interact and work in concert during attenuation
of organic chemicals in wetland systems. This review summarizes the recent progress made …

Aromatic hydrocarbons contaminate many environments worldwide, and their removal often
relies on microbial bioremediation. Whereas aerobic biodegradation has been well studied …
