透视中国环境服务业

●中国作为世界上最大的发展中国家和人口最多的国家,在经济迅速发展的同时也面临着环境问题的极大考验。●近10年来,我国环境服务业发展较快。从1993年到2000年,环境服务市场年平均增长率达到29.2%。●中国的环境市场正在快速形成,环境服务业将会拥有更多、更大的机遇。环保专家乐观预测,环境服务业潜在的商机深不可测,它将是21世纪的热门行业。     

环境服务业

我国环境服务业的主要内容简单地说,我国环境服务业的内容即为从事城市污水处理、城市垃圾处理和处置等方面的工程或活动、提供与环境分析、监测、评价和保护等方面有关的服务、环保技术与工程服务、环境研究与开发、环境培训与教育、环境核算与法律服务、咨询服务以及其他与环境有关的服务等。概括说它主要包括两个方面:一是环境污染治理服务,即从事废水处理、废弃物处理处置、大气污染控制、噪声污染控制等开发、设计及其工程总承包以及设施的运营。二是与环境管理相关的服务,即环境影响评价(评估)、环境污染治理工程可行性研究、评估以及…     

在色拉油的香味中发电

一种以回收色拉油作为燃料发电的发电机在美国问世。这款名为“BioG3000”的发电机能够制造出清洁、可重复更新的能源。发电所需的回收色拉油可从数千家餐厅收集而来。在发电过程中,发电机会散发出爆米花或炸薯条的诱人香味。用这种以回收色拉油作为燃料的发电机发电,贯彻了环保概念,在绿色发电的同时,还能散发诱人的香味,让环保也变得浪漫起来。在色拉油的香味中发电     

浅谈幼儿园实施的生态教育

生态教育的内容认识和保护生态环境的教育。让幼儿懂得生态环境是人类赖以生存和发展的基本条件之一,了解人类及其他生物与环境之间相互依存的关系,懂得珍惜、保护自然,保持生物种类、数量的相对稳定,学习防止环境污染的常识。环境道德美的教育。将保护环境、不受污染、生态平衡免遭破坏,热爱大自然,爱护益鸟、益兽、益虫等社会公德纳入幼儿园的品德教育,并充分利用环境潜移默化的教育作用,激起幼儿最真的灵性、对生活的热爱,以美陶冶情操。家庭、幼儿园的生态教育充分利用家长资源,让家长明确幼儿园的教育内容及目的,理解、支持幼儿园的工…     

呵护美好家园——生态示范区建设

1993年～1994年,内蒙古自治区阿拉善盟先后发生两次特大沙尘暴,给西北地区造成巨大损失,其中直接经济损失3.5亿元,间接经济损失15亿元,死亡失踪111人,受伤400多人,倒塌民房数万间,草场、农田均遭到严重破坏……阿拉善盟为什么会出现这样的特大沙尘暴?中科院调查认为,发源于祁连山的黑河中上游地区经济快速发展,工农业用水量增大,致使黑河每年向阿拉善盟输送的水量越来越少。黑河的下游又恰恰位于中、上游的上风向,加之上游的绿色屏障被破坏,结果中下游地区也为此付出了惨重的代价。我国许多地区的经济发展只考虑局部,而没有照顾全局,致使我…

Ecological networks and greenways in Europe: reasoning and concepts

The paper gives an overview of approaches towards ecological networks throughout Europe.It does not intend to present a complete picture,but to highlight comon developments within countries and regions and show common principles and differences between countries and regions that have to be taken into account when developing a joint European intiative,Countries or regions that have not been included can be active in the same way ,but information was not accessible to be authors for different reasons.This overview shows the comparable trends in decline of landscapes and the diversity in approaches to biodiversity conservation and nature conservation planning.Understanding the differences and common issues are of utmost imprtance to generalise common principles and to understand the way neighbours and other European partners approach problems.     

以发展循环经济为核心规划建设生态市

2003年8月26日,《扬州生态市建设规划》在北京通过国家级论证,成为指导全市生态市建设的纲领性文件。发展循环经济,是建设生态市的核心。扬州市在工作中注重始终围绕这个核心,以规划为龙头、生态示范区为基础,大胆吸引国际合作先进经验,推进生态市建设的逐步深入。     

Photodegradation of acetochlor in water and UV photoproducts identified by mass spectrometry

The sunlight photodegradation half-lives of 20 mg/L acetochlor were 151, 154 and 169 days in de-ionized water, river water and paddy water, respectively. When exposed to ultraviolet (UV) light, acetochlor in aqueous solution was rapidly degraded. The half-lives were7.1, 10.1, and 11.5 min in de-ionized water, river water and paddy water, respectively. Photopreduets of acetochlor were identified by gas chromatography/mass spectrometry(GC/MS) and found at least twelve photoproducts resulted from dechlorination with subsequent hydrtrxylation and cyclization processes. The chemical structures of ten photoproducts were presumed on the basis of mass spectrum interpretation and literature data. Photoproducts are identified as 2-ethyl-6-methylaniline; N, N-diethylaniline ; 4, 8-dimethyl-2-oxo- 1,2,3,4- tetrahydroquino-line; 2-oxo-N-(2-ethyl-6-methylphenyl)-N-(ethoxymethyl) acetamide; N-(ethoxymethyl)-2‘-ethyl-6‘-methylformanilide; 1-hydroxyaeetyl-2-ethoxyl-7-ethylind ole; 8-ethyl-l-ethoxymethyl-2-oxo-1, 2, 3, 4-tetrahydroquinoline; 4, 8-dimethyl-l-ethoxymethyl-2-oxo-1, 2, 3, 4-tetrahydroquinoline; 2-hydroxy-2‘-ethyl-6‘-methyl-N-(ethoxymethyl) acetanilide and a compound related to acetochlor. The other two photoproducts were detected by GC/MS although their chemical structure was unknown.
