雪冰中黑碳的测试分析方法综述

The general statement on the measuring methods for black carbon in snow and ice

储存在雪冰介质中的黑碳是了解古气候、古环境的变化以及人类活动历史的重要工具.然而,雪冰中黑碳信息的准确提取却不同于一般的常规离子,在测试分析的每个环节(样品采集,预处理,精确测定)都需要特别处理.本文就上个世纪80年代雪冰黑碳开始研究以来已有的测试分析方法进行了综述.

Black carbon in snow and ice is an important indicator of environment change and human activities. However, the recovery of black carbon history from snow and ice, unlike the common ions, is a relative difficult task. Special treatments are needed in the whole processes, including samples collecting, pretreating and measuring. Here, we review the measuring methods for black carbon in snow and ice used by some scientific institutions/laboratories since the 1980＇s.
