环境核素在污染物沉积断代与成因研究中的应用

土壤环境正在遭受着来自工业、农业等各种人为活动引起的污染，大量有机和无机污染物对环境和人类健康形成了危害风险，研究污染物的成因与沉积断代是进行污染调控与对污染土壤进行修复的重要依据，本文着重介绍了几种环境核素（7Be、137Cs、210Pb、13C）在污染物沉积断代与成因研究中的应用进展，并对其应用前景作了展望，以期该方法在今后对土壤环境污染风险评价和调控治理研究中发挥重要作用。

Applications of Environmental Isotopes for the Assessment on the Formation and Ages of Pollutant in Soil

As the development of industry, agriculture and other human activities, a increased risk of majority pollutant to environment and health is coming forwards. It is very important to investigate the cause, formation and ages of pollutant in soil for the purpose to control and manage the pollutant. The tracer techniques of environmental isotopes are used as a sensitive approach, which has been developed in recently years. The current developments in the use of the environmental isotopes of ^7Be,^137Cs,^210Pb,^13C and ^14C to study on the formation of pollutant, contaminative proceedings and ages are reviewed. The prospect of the applied foreground for the technique is discussed, which will provide the basic data and theories for the control of further contamination of pollutants and the remediation of polluted soil to achieve a sustainable development of agriculture and environment.
