平原区城市及周边Hg异常土壤中辰砂的发现及其特征

在我国东部平原区城市及其周边土壤Hg异常查证过程中首次发现辰砂，对其矿物学特征进行了研究，并就辰砂分布与土壤Hg异常的空间对应关系、辰砂的含量与Hg异常土壤中Hg含量间的相关性等问题进行了探讨。结果表明，辰砂是Hg异常土壤中Hg的一种主要存在形式。这一发现对研究和评价Hg异常土壤的生态环境效应具有重要的理论和实用价值。

The discovery of cinnabar in Hg-anomaly soil of cities and outskirts in plain areas and its characteristics

This paper reports the discovery of cinnabar during Hg-anomaly inspection in cities and outskirts of eastern China plain areas and describes its mineralogical characteristics. Such problems as the spatial correspondence of Hg anomaly with cinnabar distribution and the correlation between cinnabar amounts and Hg anomaly are also discussed. The research indicates that cinnabar is an important existing form of Hg in Hg-anomaly soil. This discovery has important academic and application significance in the study and evaluation of environmental effects of Hg-anomaly soil.
