| Abstract: | Stable isotope technique is a new,innovative approach to assess the source and natural attenuation of organic pollutants in environment.This review covers the recent laboratory and field development and achievements of application of stable isotope(C,H) technique on investigation of environmental behaviors of organic pollutants including chlorinated,petroleum hydrocarbons,PCBs,and so on.Based on the knowledge mentioned above,the existing problems and perspective of the application of stable isotopic fractionation in environmental research of organic pollutants are discussed.It is suggested that future research should expand the types of organic pollutants and better understand and take into account the various environmental factors that may influence the isotopic fractionation. |
