| Abstract: | Objective:To determine the content of four heavy metals in Rheum palmatum in Huadian of Dali and analyze impact factors of plant environment (soil and water). Method:The contents of lead,chromium,arsenic and mercury in Rheum palmatum were determined with atomic fluorescence. Result:The levels of all the heavy metals in samples examined were within the extent of the quality standards set up by the enterprise,and the plant environmental has no effect on the content of heavy metals in rheum; the linear range w... |
