[求助]
關(guān)于重金屬污染的疑問翻譯，求助
|
||
| 由表2-4可以看出: 工業(yè)區(qū)的污染主成分反映為因子變量在Cu、Zn、Pb﹑Ni﹑Cr上有較高的載荷,表明主要受工業(yè)污染排放的影響。研究表明: Pb 污染受冶煉廠、化工廠工業(yè)廢氣影響較為突出, 尤其是冶煉廠排出的廢氣中Pb 的含量較高, 其排放量達(dá)2.68t/a,工業(yè)廢氣中的Pb隨降塵沉降到地表進(jìn)人土壤, 使土壤中的Pb含量升高 ； 此外, 冶煉本身就容易導(dǎo)致環(huán)境中的Cu、Zn增加 。而Cu，Zn，Cr，As,Cd大部分來源于采礦、冶金工業(yè)以及工業(yè)廢料,所有這些均可能引起工業(yè)區(qū)土壤重金屬含量的升高。 |

| It can be seen from Table 2-4: Industrial Zone of pollution principal component reflects the higher load factor variables of Cu, Zn, Pb, Ni, Cr, indicating that mainly affected by the impact of industrial pollution emissions. Studies have shown that: Pb pollution by the smelter, chemical plant industrial emissions are more prominent, especially the high Pb in smelter exhausts its emissions amounted to 2.68t / a, industrial emissions of Pb with dust suppression settlement to the surface into the soil, the Pb content in the soil increased; in addition, the smelting itself easily lead to the environment, Cu and Zn in increase. While Cu and Zn in and Cr, As and Cd in most of the from the mining, metallurgical industry, as well as industrial waste, all of which may cause the industrial zone of soil heavy metal content increased. |
