本文以上海的重要水源地——淀山湖为研究对象，通过对研究区沉积物中重金属元素Cu、Cd、Cr、Hg、Pb、As的时空分布规律以及它们在沉积物中随时间或沉积深度的形态分布及迁移转化规律的研究，综合考虑区域工农业发展现状和历史对沉积物中重金属元素含量及分布的影响，对区域重金属污染历史及效应进行分析论证。

Meanwhile, the concentration of Pb,Zn and other heavy metals is rather high in the oxidation zone and decreasesdownward to levels that are unbelievably low for Pb-Zn mine tailings. Theseobservations suggest that heavy metals should be re-immobilized by secondaryminerals, rather than primary minerals, in the oxidation zone, and could be leachedout from suboxic environment due to low rate oxidative dissolution which preventsthe precipitation of secondary minerals in significant amount. Thus, cover scenarioswhich establish a suboxic environment beneath the cover layer might not always beeffective in preventing heavy metal release from mine tailings.Sequential extraction studies indicate that, in addition to heavy metal leaching,oxidation of the mine tailings increased the mobility of residual Zn, and Cu, while Pb remains immobile due to the formation of anglesite (PbSO4). Using the seven-step extraction technique developed by Dold (J. Geochem. Explor., 2003, 80: 55-68), galena dissolves in significant amount at step 2 most probably due to the strong complexing of Pb2+ by acetate, while other metal sulfides dissolve at step 6, which suggest that this extraction technique could not be used to evaluate the mobility of lead in natural environment

重金属含量均低于新鲜尾矿，但以硬化层中的含量最高(Pb、Zn含量分别为0.47%和0.93%)，往下大幅度降低，表明尾矿风化过程中形成的次生矿物对Pb、Zn等重金属元素有较强的固定作用，而次氧化带的淋溶作用造成了金属元素的大量流失；(4)与新鲜尾矿相比，硬化层中铅的可迁移性大大降低，硬化层之下尾矿样品中铅的可迁移性也不同程度降低，这是由于硫化物氧化产生的硫酸根与尾矿中的铅反应形成铅矾(PbSO_4)的缘故；(5)氧化作用使尾矿中的zn、Cu等重金属的可迁移性不同程度地增大，其中对锌的可迁移性影响最大，铜的可迁移性与铁比较相似，铅则容易与硫化物氧化形成的SO_4~(2-)反应形成铅矾(PbSO_4)；(6)为了减少尾矿污染和修复矿山环境，人们提出了各种不同的尾矿覆盖方案，本文的研究结果表明，这些方法不一定能够有效地阻滞污染元素的迁移。

以邪恶、异教崇拜以及撒旦思想为其主要诉求，通常在歌词含有反基督、反宗教的倾向即被归为黑金属，除了传统重金属固定乐器之外，经常会使用其他乐器如钢琴、小提琴，或歌剧的女高音，在歌曲中营造出一股诡异又吓人的恐怖气氛。"黑金属"以来自北欧的重金属团体最具代表性。1、启蒙黑金属：在八十年代初，英国的地下重金属乐队Venom，在音乐中明确宣扬了对撒旦的崇拜、对战争的渴望，并且是由他们第一次将"Black Metal"这个名词带到金属圈内，为日后的黑金属乐队指明了音乐方向；瑞典同样出现了两支启蒙型的黑金属乐队，Bathory和Celtic Frost，他们的音乐已经基本上具备了原始黑金属的特点：粗糙、暴虐、邪恶！而Bathory的第一张专辑也被誉为是第一张黑金属唱片。不能不提的是丹麦的Mercyful Fate，他们虽然对日后的原始黑金属没有什么过多的影响，但是却对歌特黑金属、交响黑金属、歌特金属有着榜样的作用。

The process of ecological degradation in the vicinity of Shaoguan Pb/Zn smelter may be summed as: heavy metals and acidic deposits from the waste gas from smelter resulted in the vanishment of the sensitive plant species, increasing accumulation of heavy metals in soils and acidification of topsoil worsened the chemical properties and then shallow-rooted plant, mainly the herbaceous, vanished. With the demolishment of the vegetation cover, increasing water-soil erosion worsened physico-chemical properties of soil and, subsequently, some woody plants disappeared and barren land was finally appeared.

该生态系统的退化过程可以归纳为：来自于冶炼废气的重金属和酸沉降导致了敏感植物的消亡，丧失了对土壤的缓冲保护作用；重金属在土壤表层的积累，酸性物质在土壤表层的增加导致的土壤酸化以及由此引发的有机质与养分的淋溶和重金属及Al的活性增加，加剧植被的快速退化，特别是浅根植物的衰亡；地被层的破坏，导致水土流失和土壤侵蚀加深，进一步恶化表层土壤的理化性质，一些木本植物随之消失，最终形成光板地。
