针对“磐五味”存在的重金属超标问题，作者依托农业地质环境调查项目对磐安中药材产地环境开展岩-土-药材系统研究发现，岩石在风化成土过程中淋溶作用强烈，Ca、Mg等流失殆尽，Cd、Cu等重金属相对富集。从土壤母质、淋溶层到土壤表层，pH值由高到低，酸化强烈。研究表明，表层土壤Cd、Cu相对累积和土壤酸度增强，是中药材Cd、Cu超标的主要原因。

In view of the situation that heavy metal content of"five kinds of traditional Chinese medicinal materials in Pan'an" exceeds the standard, the authors carried out systematic "rock-soil-medicinal material" research and, based on agro-geological environmental survey, investigated geographical environment of Pan'an. The results show that rocks have experienced strong eluviation in the weathe-ring and soil-forming process, which results in the loss of Ca and Mg and enrichment of Cd and Cu. Soil acidification is obvious, and soil pH values tend to decrease from soil parent layer, leached layer to plough layer. The excessive Cu and Cd in the traditional Chinese medicinal material results from relative accumulation of Cu and Cd in the surface soil and the increased soil acidity.
