种植方式对植物体内重金属含量影响及健康风险评价(6000字)
摘 要:株洲属于标准的工业城市,到处充满着工业排放的气体。我们从株洲工业区采取的植物样品大豆、玉米进行研究分析,通过F型火焰原子吸收分光光度计的测量,对比2种种植方式发现,套种模式的植物比普通种值模式的重金属含量要高。并测得其样品重金属铜、锌、铅、镉不同程度超过国家规定的最大标准值,其中镉的超标最为严重。

The Affection by Cultivation Method on Plant`s Metal
Content and its Health
Abstract: Zhuzhou, the standard industrial city, is full of industrial emissions. We collected the beam and corn samples from this industrial zone, and by applying the F-type flame atomic absorption spectrophotometer measurements for these two speciments, we found that the heavy metal content in intercropping-pattern plant are higher than ordinary cultivated plant, and the heavy metals such as Copper, Zinc, Lead, Cadmium from intercropping-pattern plant have all surpassed nation`s maximum standards, of which the Cadmium exceeds the most.
