环境保护部强化废旧家电拆解处理环境监管

为落实国务院促进扩大内需鼓励家电“以旧换新”政策，保障“以旧换新”过程产生的废旧家电得到妥善拆解处理，推动《废弃电器电子产品回收处理管理条例》（国务院令第551号，以下简称《条例》）的贯彻落实，环境保护部日前发布了《关于贯彻落实家电以旧换新政策加强废旧家电拆解处理环境管理的指导意见》（以下简称（（指导意见》），要求试点省市环保部门提高认识，明确思路，切实做好废旧家电拆解处理的组织实施和监督管理工作。     

“惠民”企业的节能标准征途

对于节能产品惠民工程和家电下乡这两类享受国家财政补贴的惠民政策来说,产品的节能性是不容忽略的重要指标。9月初,本刊记者深入安徽省这两类惠民政策的中标企业,探访他们在节能标准方面的前世今生,追寻他们的节能标准之路。     

远离“堵市”,低碳交通如何圆梦?

在城市里,堵车已是常态,成为一种城市病。从国内的一线城市到三四线城市,堵车每天都在上演。堵车会增加油耗,排放更多的汽车尾气,成为机动车污染的一个因子。如何让城市的道路畅通起来,迎来低碳交通,这是每一个都市人的梦想。习惯性堵车Duang!又堵车了!3月13日晚上六点,合肥市出租车司机郑兴国载着乘客被堵在了南一环上的安徽省人大门口,这让他心情一下子就不好了。“这个时候,根本不能进市里。”郑兴国懊恼地说。     

节能电脑让娱乐更加“绿色”

聊天、游戏、听歌、看电影……如今电脑的娱乐性是越来越强了。不过,随着电脑功能的丰富发展,这不断上涨的电费也着实让人感到头疼。面对人们的心理变化, 一些精明的电脑生产厂商不失时机地推出了号称更绿色更环保的“节能电脑”。这节能家电相信对大家来说已经算不上什么新鲜事物了,但电脑产品的节能可能大家都还是第一次听说,它又有哪些节能的高招呢?     

寻找基层环保宣教的着力点

因为轮岗,长丰县环保局党组成员王余胜来到环保局已经四年多的时间。在此之前,他在长丰县交通局交通运输管理所担任所长。这样的跨界,曾让他很忐忑。去年长丰县环保局调整领导分工时,王余胜分管起了宣教工作,这是一个让他熟悉又陌生的工作。熟悉是因为此前在交通系统的时候,他曾是《中国交通报》的优秀通讯员,有过新闻报道的经验,陌生是因为他对环保宣教工作了解不多,是个外行"。在     

宜昌的森防卫士——记湖北宜昌森防高工肖德林

正他是林业专家,也是树木医生;他50余年风雨无阻,将毕生心血抛洒在广袤的森林里;他发扬"除害、敬业、厚德、求是"的"啄木鸟精神",足迹踏遍山间小路,汗水浇洒树林深处,为一个个"不能言语"的"病人"问诊把脉、开方施药,让森林生机盎然,让宜昌绿色常在。他就是湖北省宜昌市森林病     

观点

“半城市化”受到不同方面的批评,其中“体制派”认为,正是城乡二元结构和户籍制度使农民无法真正进城,应当建立城乡统一的制度,让进城农民可以变身市民。“资源派”则称,“半城市化”让农民保留了农村的宅基地、承包地,又在城市工作生活,结果是既无法安心进城,又不能安心留村。若让农民用宅基地、承包地换城市户籍和社保,就可以节约资源,提高城市化率等。     

扩大内需,没有简单药方

出口导向,成绩很大,问题很多,向内需转型,迫在眉睫。为此就必须要让工人农民组织起来,获得参与一次分配的权利,但是目前却难以实现。旧模式无法为继,新转型又难以短期内稳定地完成,这就是中国面临的两难困境。对付复杂问题,没有简单药方。     

柴尔红:“藏水思想家”的小试验

柴尔红一心只想让家乡甘肃民勤县多存些水。他的家庭节能节水改造,最想保护的也是水。柴尔红老在说这句话:"水一定不能裸露,只有一裸露,就完蛋了。"过去担任小学老师,后来担任中学老师的柴尔红,无意间养成了讲课的习气。     

像对贫困宣战一样向污染宣战

正"我们要像对贫困宣战一样,坚决向污染宣战。"这是政府工作报告中铿锵的宣言,表达了强烈的政治意愿。污染是另一种"贫困"的表现。"雾霾天气范围扩大,环境污染矛盾突出,是大自然向粗放发展方式亮起的红灯。"而"重症污染"就是一种"严重贫困",只要抬头看天、低头看水即可把症状看得一清二楚。如果镜不见花、水不见月,这样的生活有什么意思?雾霾确实已经成为很多城市的标志性难题。今年     

Degradation of oilwell cement due to exposure to carbonated brine

The growing interest in geologic carbon sequestration has highlighted the need for more data on how well cements react to CO₂ exposure. This paper describes a series of experiments that was conducted to examine the effects of flowing carbonated brine on well cements. Class H cement pastes were exposed to the ranges of temperature (20–50 °C) and pH (2.4–5) characteristic of geosequestration conditions at a depth of about 1 km. The exposed cements and the reactor effluents were analyzed using multiple techniques including optical microscopy, X-ray diffraction, EPMA, and ICP-OES. The results showed that if the solution was pre-equilibrated with calcium carbonate, as would be expected in a limestone formation, there was no detectable attack. However, under the pH and temperature conditions to be expected in a sandstone formation, the initial rate of attack was on the order of millimeters per month. The outer layers of the cements reacted under sandstone-like conditions were fully degraded based on the results of the XRD and EPMA analyses. Inside the degraded layers there was a calcium carbonate-rich layer, a layer depleted of calcium hydroxide, and an unreacted cement core. The rate of degradation of the cement in these experiments was controlled by the rate of dissolution of the calcium carbonate-rich layer, after its formation, and diffusion through the fully degraded layers.     

Listening to local voices: Tuvaluans respond to climate change

Climate change has become a permanent feature on the global media scene and in the decision-making of policy makers. The voices of academics, scientists, politicians and commentators dominate the climate change debate, yet local knowledges and beliefs, local realities, as well as local voices and actions are essential elements of navigating the way forward. Drawing on Paton's postgraduate research, this paper broadens the current dialogue by providing a platform for grassroots Tuvaluan voices to enter the climate change debate. It explores their local realities, knowledges and beliefs, and captures what Tuvaluans hold dear – factors which must play a central role in decision-making processes. To ensure the local population is fully mobilised, it will be argued that processes for engaging local voices must build on existing forums for engagement.     

如何抓住孩子让环保走进家庭

从家庭方面讲，关于环保知识人们又了解多少，观念上又重视多少呢？尤其是农村家庭。我采访了很多人，他们都觉得太忙，没有闲暇关心这些。谈到环保，人们表现的也很茫然，当然他们也知道沙尘暴、也知道水灾、台风和旱情，但成因就不得而知了。具体到人们的生活，什么节约水电、废物利用、垃圾的分类回收，农村人尤其是那些围着锅台转的主妇们，根本不明白为什么要这样做。因此，我认为，环保教育不在于向家庭普及些什么，如何普及才是最重要的！孩子，是纽带，是让环保走进家庭的一条有效途径。但是，让环保走进家庭，不能像布置语文作业，…     

Building a model of commitment to the natural environment to predict ecological behavior and willingness to sacrifice

We examined the connection between individuals’ relationships with the natural environment and their environmental behaviors with a focus on commitment to the environment, defined as psychological attachment and long-term orientation to the natural world. Commitment is theorized to emerge from structural interdependence with the environment and to lead to pro-environmental behaviors. Close relationships research has identified three key antecedents to commitment (satisfaction, alternatives, and investments). We developed environment-specific measures of these constructs, and factor analysis verified three distinct factors. A path analysis revealed that satisfaction with the environment and investments in the environment, but not alternatives to the environment, predicted commitment to the environment. Moreover, commitment mediated the effects of satisfaction and investments on general ecological behavior and willingness to sacrifice for the environment. In regression analyses, commitment predicted general ecological behavior and willingness to sacrifice for the environment, even when controlling for ecological worldview, inclusion of nature in the self, connectedness to nature, and environmental identity. Individuals who are satisfied with and invested in the natural world are likely to be committed to the environment and act with the well-being of the environment in mind.     

Oil to 2000

Current surplus oil production capacity had its origins in the price increases of the 1970s. Those increases encouraged both energy conservation and the entry of new producers. Recent increases in oil demand reflect the belief among energy users that in real terms in the long term, prices will be stable. There is good reason to believe that this will be so, even at the current rate of increase it will be 15 years before demand matches current capacity. Given that situation it is difficult to see OPEC following any other pricing policy than the one currently in place. In the meantime market prices will further encourage vertical integration.
