环境地球化学研究近十年若干新进展

Some Progresses in Environmental Geochemistry Study in China in the Past Decade

环境地球化学学科在中国生态文明和美丽中国建设、国际环境公约履约及过去全球变化研究中发挥着越来越大的作用。本文简要回顾了中国过去十年在环境地球化学领域的部分研究进展,介绍了汞、持久性有机污染物和其他重金属污染物长距离传输研究进展;总结了汞、镉、锑、铊等非传统稳定同位素在地表生物地球化学循环过程中的同位素分馏规律及污染来源和环境过程示踪方面的研究进展;回顾了传统稳定同位素地球化学与污染示踪及过去全球变化方面的研究进展。指出了以上研究方向还存在的问题及未来研究方向。

In this paper, we summarized some of the research progress accomplished by Chinese scientists in the field of environmental geochemistry in the last decade. We introduced the research progress in long range transport of mercury, persistent organic pollutants(POPs) and other heavy metals in the environment. We summarized the progress in the fractionation of non-traditional stable isotopes during the biogeochemical cycling in the surface environment and application of non-traditional stable isotopes in tracing the source and environmental process of heavy metal pollution. We also introduced the progress in using traditional stable isotopes to reconstruct the climate change and to trace the sources of pollutants in the environment. Meanwhile, we suggested knowledge gaps and research needs of above research areas. We strongly believed that environmental geochemistry will play a more important role in the eco-civilization and beautiful China development plan, the implementation of international environmental conventions and the study of global change.
