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 …

Contamination by chloroethenes has a severe negative effect on both the environment and
human health. This has prompted intensive remediation activity in recent years, along with …

Extensive use and inadequate disposal of chloroethenes have led to prevalent groundwater
contamination worldwide. The occurrence of the lesser chlorinated ethenes [ie vinyl chloride …

Reliable prediction of the unsaturated zone transport and attenuation of dissolved-phase
VOC (volatile organic compound) plumes leached from shallow source zones is a complex …

Compound specific stable isotope analysis (CSIA) has been established as a viable tool for
proving, characterizing and assessing degradation of organic pollutants within contaminated …

Enhanced analytical capabilities and separation techniques, improved detection limits, and
accessibility of instrumentation have led to massive strides in the use of isotopes to assess …

Contamination of aquifers and vadose zones with chlorinated aliphatic hydrocarbons (CAH)
is a world-wide issue. Unlike other reactions, direct aerobic oxidation (DAO) of CAHs does …

Because of a range of different industrial activities, sites contaminated with chloroethenes
are a world-wide problem. Chloroethenes can be biodegraded by reductive dechlorination …

Chlorinated volatile organic compounds (CVOCs) are persistent organic pollutants which
are harmful to public health and the environment. Many CVOCs occur in substantial …

Considering the high costs and technical difficulties associated with conventional
remediation strategies, in situ biodegradation has become a promising approach for …
