The results show that all aluminum anodizing sludges were slightly neutral to acidic and mainly consist of more than 50% Al2O3; the similar total contents of Cu, Pb, Zn, Ni, Cd, and Cr in the 7 samples were found, namely, the concentrations of Pb, Cd were relatively lower, but that of Cu, Zn, Ni, and Cr were higher; the leaching tests indicate that all the samples were classed as nonhazardous wastes; but each of metals in the sample shows very different leaching behavior, possibly depending on their total contents and the final pH of leachates.
结果表明,铝型材污泥属于中性偏酸性物质,主要由Al2O3组成,含量在50%以上。各试样中Cu、Pb、Zn、Ni、Cd及Cr的总含量的分布趋势基本是一致的,其中Pb、Cd的含量较低,Cu、Zn、Ni及 Cr的含量较高。浸出毒性试验表明铝型材污泥属于非危险废物,但污泥中各重金属的浸出特性又各自不同,可能主要与它们在试样中的总含量和浸出液的最终pH值有关。

The results showed that Pb, Cd and Cu in the leaves of plants were positively related to their concentration in air significantly. The content of heavy metal in plant leaves was obviously associated with the heavy metal properties, pollution conditions and tree species. Platanus hispanica had a higher accumulation in Pb, While Populus deltoides in Cd and Cu.
研究表明,植物叶片中重金属Pb、Cd和Cu的累积量与大气中Pb、Cd和Cu的相对含量呈显著正相关;所调查绿化树种叶片的重金属含量因重金属种类、采样区和树种的不同具有明显差异,悬铃木叶片累积Pb的能力最强,而杨树叶片对Cd和Cu的累积能力最强。

It is revealed in the study that the heavy metal concentration of Pb,Cu,Zn in the leaves of urban trees (Sabina chinesis,Platycladus orientalis,Euonymus japonicus,Platanus acerifolia, Prunus cerasifera) is significantly related with the relative heavy metal contents in atmospheres of different urban regions of Yantai city, while no such relationship is found in heavy metal Cd, and that the heavy metal amounts of Pb,Cd,Cu,Zn in urban soils had no direct impacts on the heavy metal concentrations in leaves of urban trees.
通过对烟台市区不同大气污染区域绿化植物叶片中重金属Pb,Cd,Cu,Zn富积量和大气与土壤中相应重金属的含量研究分析发现,植物叶片中重金属Pb,Cu和Zn的富积量与大气中Pb,Cu和Zn的相对含量呈显著的正相关,而植物叶片中Cd的富积量与大气中重金属的相对含量相关不显著。
