摘　　要：探讨了向小鼠(Mus musculus)饲喂添加铅或镉试剂或经过稳定处理的重金属污染土壤后小鼠粪便重金属含量的变化。结果表明:当向饲料中添加铅或镉试剂时,其粪便铅和镉含量与饲料铅或镉添加量呈显著正相关关系(P<0.05),相同重金属用量下,第10 d粪便重金属含量高于第2 d。粪便不同重金属含量之间呈现较为复杂的关系,这可能与小鼠吸收过程中重金属的相互作用有关。污染土壤经过磷酸盐和膨润土稳定并未影响小鼠对土壤中重金属的吸收。This study was conducted to investigate the variation of heavy metal content in feces of mice(Mus musculus)fed lead or cadmium reagent or immobilized heavy metal contaminated soil.The results showed that there was a significant positive correlation between fecal lead and cadmium content and dietary lead or cadmium content(P<0.05).Under the same heavy metal dosage,fecal heavy metal content on day 10 was higher than that on day 2.There were complex relationships between the contents of different heavy metals in feces,which might be related to the interaction of heavy metals in the absorption process of mice.Soil immobilization by phosphate and bentonite did not affect Mus musculus absorption of heavy metals in soil.
