守护绿水青山,留住蓝天白云,是全体人民福祉所系.然而"阴魂不散"的雾霾使得PM2.5值一度居高不下,大家"闻之色变",尤其是进入冬季后,空气质量更让人为之担阮,节能减排、改善环境质量成为许多人关注的重点话题.具体到通信运营企业,其能耗主题是电.

国家发展和改革委员会有关负责人近日表示,到2017年,将在全国范围内基本淘汰黄标车,全面供应符合国家第五阶段标准的车用汽、柴油,并使京津冀、"长三角"、"珠三角"等区域人均公共交通设施拥有水平比2012年提高30%."上述目标的提出,旨在强化机动车污染综合防治、尽快改善空气环境质量."上述负责人介

环保部发布的《2011中国环境状况公报》指出,截至2011年底,全国大多数地区已全面开展涵盖空气、水、固废和噪声等4大领域的污染指标检测工作.

山西太星蓝天环保科技有限公司,成功研制出国内首台苯并芘在线检测仪.该仪器为全面掌握环境空气中的苯并芘含量,进而强化对苯并芘的污染控制提供了及时、有效的技术支撑.

今年北京启动对灰霾元凶PM2.5的监测,同样行动起来的还有另外多个城市.不过尽管我国大气污染远没有当年欧美严重,但治理好灰霾起码也要20~30年.另外,如果中国按照WHO的质量准则分第一阶段、第二阶段、第三阶段、第四阶段这么四步走,每一步考虑是3~5年的话,也要20年.有业内人士说,按国标,目前全国70%的城市空气质量达标;但如果增加PM2.5监测指数,则全国70%

分别采用空气、氩气大气压介质阻挡放电(DBD)等离子体对重油进行了处理.对经空气DBD等离子体处理后的重油进行粘温特性分析,发现重油粘度升高,流动性变差.红外光谱和四组分分析结果表明重油的重质组分含量升高,重油胶体体系被破坏,同时生成大量刺激性气味气体.为了便于分析气态产物的成分和含量,采用大气压氩气DBD等离子体处理重油并收集气体产物.气相色谱分析发现生成气中含有大量C1-C5的烃类和一定量氢气,其中氢气和甲烷含量占生成气的70%以上.实验结果表明重油在等离子体作用下既发生裂解又发生聚合反应,既生成低碳烃类,本身的流动性也变差.

中国计量院气体研究室是我国气体化学计量的溯源单位.在长期的科研实践中,气体研究室在国内标准气体研究和气体分析研究领域处于领先地位,同时,该室还拥有一批先进的高纯气体大中型分析测试仪器和先进的实验室设施.近年来,他们的一系列科技成果已经得到成功推广应用,如室内空气质量评价及相关标准物质研制等,为保障人民生命安全及国家重大工程建设提供了有力支撑.

Most seabird species display colonial behavior during the breeding period which implies that food resources around breeding sites can easily go depleted. Seabirds need to both reach profitable areas, which can be located far from the colony, and return to the colony regularly. In this context, flexibility in movement behavior may be crucial for breeding success. During chick-rearing, Procellariformes species can alternate short trips lasting 1-4 days for chick provisioning with longer trips for self-provisioning in what has been called a dual-foraging strategy. We analyzed foraging trips from 136 Scopoli's shearwaters from three Mediterranean colonies tracked with GPS during 6 chick-rearing seasons to assess whether the adoption of a dual fo- raging strategy depends on the quality of habitat surrounding the colony. We found a marked dual-foraging strategy only in birds from the Linosa colony which was the largest colony in terms of breeding pairs and was characterized by having a lower marine habitat quality. Birds from this colony performed foraging trips that extended up to 369 km from the nest and lasted more than 10 days. In general, the decision to perform long lasting trips was triggered by lower values of primary production and higher offspring weight. Contrary to expectation, the decision to feed far from the colony was not related to the parents' weight. At the same time, despite the higher productivity offered by distant areas, the higher proportion of long trips performed by birds breeding in poor areas was not sufficient to maintain the same body mass as the ones breeding in richer areas [Current Zoology 60 (5): 622-630, 2014].

很多人称马军是个不折不扣的环保斗士,因为他在过去五年里描绘出中国水污染地图、空气污染地图和固体废物污染地图.2011年,马军将苹果等29家知名IT企业的名字和重金属污染联系在一起;今年,马军再次联合各大NGO组织,发布第二期绿色选择纺织业调
