| Abstract: | Compound-specific stable isotope analysis(CSIA) using gas chromatography-isotope ratio mass spectrometry(GC-C-IRMS) has developed into a mature analytical method in many applications and thus is widely used in contamination studies during the past decade.In the study of groundwater contamination,successful applications of CSIA data were involved in the allocation of contaminant sources on a local and regional scale;the identification and quantification of bio-transformation reactions at contaminated field s... |
