在这研究， Cd (II ) 的联合效果， Pb (II ) 和 Solidago Canadensis L 上的 atrazine (ATR ) 。被调查。结果证明包含 Cd， Pb 和 ATR 的土壤能禁止 Solidago Canadensis 的根延伸 L. ，和那在根延伸的禁止的率和 Pb (II ) 的集中之间有一种积极线性关系。Cd (II ) 和在土壤的 -ATR 显示出的 Pb (II ) 的混合根和 Solidago Canadensis L 的射击生物资源上的重要不利效果。当 Cd (II )-ATR 集中比 1.0 TUmix (Cd+ATR ) 的那些高时，在 Cd (II )-ATR, 的更低的集中稍微增加的 Acetylsalicylic 酸(ASA ) 内容然后减少了。Solidago Canadensis L 的 ASA 内容上的 Pb (II )-ATR 的有毒的效果。比 Cd (II )-ATR 的大。可溶的糖内容第一与增加 Cd (II )-ATR 的集中减少了然后增加并且与增加 Pb (II )-ATR 的集中显示了变化。全部的蛋白质内容与相对控制样品增加 Cd (II ) 和 Pb (II )-ATR, 的集中增加了。NP 嘘，内容证明直到 Cd (II )-ATR, 的 12.2 mg/gfw 的重要增加在 14 天暴露以后由重要衰落列在后面到 4.5 mg/gfw。Pb (II )-ATR 的效果类似于 Cd (II )-ATR 的但是数量 NP 嘘不比 Cd (II )-ATR 的高。

英文摘要：

In this study, the joint effects of Cd（ Ⅱ）, Pb（Ⅱ ） and atrazine （ATR） on Solidago Canadensis L. were investigated. The results showed that soil containing Cd, Pb and ATR could inhibit root elongation of Solidago Canadensis L., and that there was a positive linear relationship between the inhibitory rate of root elongation and the concentrations of Pb（Ⅱ ）. The mixture of Cd（ Ⅱ ） and Pb（Ⅱ ）-ATR in soil showed a significant adverse effect on root and shoot biomass of Solidago Canadensis L. Acetylsalicylic acid （ASA） contents increased slightly at the lower concentrations of Cd（Ⅱ ）-ATR, then decreased when Cd（Ⅱ）-ATR concentrations were higher than those of 1.0 TUmix（Cd＋ATR）. The toxic effect of Pb（Ⅱ）-ATR on the ASA contents of Solidago Canadensis L. was greater than that of Cd（Ⅱ ）-ATR. Soluble sugar contents firstly decreased and then increased with increasing concentrations of Cd（Ⅱ）-ATR and displayed fluctuation with increasing concentrations of Pb（Ⅱ ）-ATR. Total protein contents increased with increasing concentrations of Cd（Ⅱ） and Pb（ Ⅱ ）-ATR, relative to the control sample. The NP-SH contents showed a significant increase up to 12.2 mg/gfw of Cd（Ⅱ）-ATR, followed by a significant decline to 4.5 mg/gfw after 14 days of exposure. The effect of Pb（ Ⅱ ）-ATR was similar to that of Cd（ Ⅱ）-ATR but the amount of NP-SH was not higher than that of Cd（ Ⅱ）-ATR.
