Rapid industrialization and population explosion has resulted in the generation and
dumping of various contaminants into the environment. These harmful compounds …

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 …

▪ Abstract The natural production and anthropogenic release of halogenated hydrocarbons
into the environment has been the likely driving force for the evolution of an unexpectedly …

Compound-specific stable isotope analysis (CSIA) using gas chromatography-isotope ratio
mass spectrometry (GC/IRMS) has developed into a mature analytical method in many …

The assessment of biodegradation in contaminated aquifers has become an issue of
increasing importance in the recent years. To some extent, this can be related to the …

Biodegradation of chloroethene compounds has been a matter of intense scientific
investigation since these compounds were first identified in the late 1970s as common …

The following sections summarize the major topics involved in in situ bioremediation of
soluble phase (dissolved) chlorinated solvents in groundwater. This introduction is designed …

Bioremediation has historically been approached as a 'black box'in terms of our fundamental
understanding. Thus it succeeds and fails, seldom without a complete understanding of why …

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 …

Electrokinetic remediation is effective for extraction of contaminants, such as heavy metals,
from fine grained deposits. However, several challenges have led to limited field …
