[Study on heavy metals in growing area soils and young fruit of Citrus grandis 'Tomentosa'].
OBJECTIVE
To determine the status of heavy metals contamination in growing area soils and young fruits of Citrus grandis.


METHODS
Application of Nemerow's index for heavy metals assessment of soil and young fruit of Citrus grandis, as well as according to national environmental quality standard for soils and green trade standards of importing & exporting medicinal plants & preparations.


RESULTS
The heavy metals content of most of the growing area soils of Citrus grandis rates as first, and of the rest ones rates as second. The heavy metals content in young fruits of Citrus grandis is within the limitation of quantity of criteria.
