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。

Methods: The following five sites in the city were selected as monitoring spots, namely, the First Smelter of Tongling Nonferrous Metal Group, the second Smelter of Tongling Nonferrous Metal Group, the Changjiang High-speed Passageway, Fenghuangshan Copper Mine district, residential area, respectively. The moss species Hypnum plumaeform e collected from Huangshan mountain was placed in nylon bag of 15.5 cm×5.5 cm in size and 2.0 mm×2.0 mm in meshes, with each bag having 3 g moss and then sealed by a nylon wire. Moss bags were suspended in five urban exposure sites and then gathered after two months. The content of heavy metal in the tested moss were analysed by atomic absorption spectroscopy.

The main fi ndings were i copper was strongly bound to organic layer and seemed to be the main pollutant in the ecosystem while zinc was the most mobile element and did not accumulate to any specifi c part of the ecosystem, ii the forest mosses and epiphytic lichens were the most sensitive plant species and the seedlings of the vascular plants that had survived near the smelter were absent, iii there was a highly resistant soil decomposer community near the smelter although the activity of the soil animals and microbiota was low and their community structure altered, iv many insect species also suffered from pollution although the adverse effects caused by forest pests increased with pollutant load, v the low survival rate and breeding success of hole-nesting passerines near the smelter was caused by habitat changes and the quality of food, vi the adverse effects seem to be to some extent reversible after decreased pollutant load or remediation actions.

主要fi ndings是i铜强烈一定到有机层数、并且似乎是主要污染物在生态系、当锌是最流动的元素，并且没有积累对生态系时的任何specifi c零件， ii森林青苔和附生植物地衣是含羞草种类，并且在精炼工附近生存了是缺席维管束植物的幼木， iii有一个高度抗性土壤decomposer社区在精炼工附近、虽然土壤动物和microbiota的活动是低的、并且他们的修改过的社区结构、iv许多昆虫种类也遭受污染、虽然森林造成的不利影响虫增加了与污染物装载、v孔嵌套雀形目鸟的低生存率和繁殖的成功在精炼工附近是由栖所变动造成的，并且食物的质量， vi不利影响似乎在某种程度上是双面布料在减少的污染物装载或治疗行动以后。

Additionally, a fire at the 145,000 tpy Holyhead smelter and coal supply difficulties at the 360,000 tpy Angul smelter in India increased the uncertainty for production levels.

另外，年产能145，000吨的Holyhead冶炼厂爆发火灾，印度年产能360，000吨的Angul冶炼厂煤炭供应困难使得这些冶炼厂产量水平的不确定性上升。

Aluminium prices started the second week of July with a spurt above US$3,300/t on the back of production woes coming from the Shanxi region in China. Previous attempts to breach the US$3,100/t barrier in June and May were short lived with prices not finding the support needed to stay above those levels. Aluminium bounced back with renewed strength in July on further power driven supply fears and new long positions entering the market. In June momentum came from production disruptions in UK (at the 145,000 tpy Holyhead smelter) and India (at the 360,000 tpy Angul smelter) and news that two smelters in the US (Glencore's 168,000 tpy Columbia Falls and Alcoa's 267,000 tpy Rockdale smelters) were curtailing their production levels on the back of prohibitive power prices. LME 3M prices tested the US$3,200/t level at the end of the month but the bulls appeared to hesitate to bridge that mark retreating towards US$3,150/t at the beginning of July.

中国山西的生产危机推动铝价在7月份第二周周初站上3，300美元/吨。5月份和6月份铝价试图突破3，100美元/吨的关口，但这仅是昙花一现，铝价并没有找到站上这个价位的支撑。7月份铝价反弹，电力危机引发供应担忧以及新的多头进场推动铝价走强。6月份，英国（年产能145，000吨/年的Holyhead冶炼厂），印度（年产能360，000吨的Angul冶炼厂）以及美国两座冶炼厂（Glencore公司旗下年产能168，000吨的Columbia Falls冶炼厂和Alcoa公司旗下年产能267，000吨的Rockdale冶炼厂）因电价上涨宣布减产，从而为铝价走势提供了动能。6月末，LME三个月期铝价格上探3，200美元/吨这一价位，但市场做多动力不足，铝价在7月初回调至3，150美元/吨。
