环境污染对生态危害经济损失评估模式的研究

定量评估环境污染对生态环境危害的经济损失,是环境科学研究的课题。本文从风险评价和环境经济学角度,提出环境污染对生态环境危害经济损失的评估模式。     

福州青年运动会环境空气质量状况及原因分析

利用2015年10月福州市国控点位空气质量常规6项参数(SO_2、NO_2、CO、O_3、PM_(10)、PM_(2.5))、NCEP/NCAR再分析逐日高度场、风场资料、温度场资料(垂直方向为17层,分辨率为2.5°×2.5°),对10月及福州第一届青年运动会(以下简称"青运会")期间空气质量进行分析与评价,并结合采取的相关管控措施和气象条件情况,分析福州市空气质量变化原因。结果表明,2015年10月福州市空气质量达到优良水平,各项污染物指标均达到一级标准,浓度较2014年同期明显下降,同时青运会期间污染物浓度较10月显著降低,这与对重点工业源、流动源、扬尘源等采取的管控措施密不可分,而且青运会前期受台风"巨爵"外围气流影响,福州温度较常年偏高,有利于空气垂直湍流运动,青运会后期的降水清洁过程,易于污染物清除。     

Currently used organophosphate and brominated flame retardants in the environment of China and other developing countries (2000–2016)

This review summarizes the environmental occurrence of new brominated flame retardants (NBFRs) and organophosphate compounds (OPs) in the environment of developing countries since 2000. The ban on the production and use of commercial formulations of polybrominated diphenyl ethers (PBDEs) have paved the way for the high use of NBFRs and OPs in consumer products to fulfill the fire safety regulations. Recent studies have shown that the ever increasing production volumes and extensive use of these chemicals as additive FRs and plasticizers have resulted into their ubiquitous occurrence in all environmental compartments. Although presumed to be safe for use and the environment, recent studies on their occurrence and persistence in the environment have raised questions. Due to the lack of awareness, research interest, and availability of technical facilities, limited scientific data is available on the occurrence of these chemicals in developing countries. In this study, we collected reported data and provide an overview of environmental occurrence of NBFRs and OPs in abiotic and biotic matrices of different developing countries. Finally, research gaps were identified with recommendations for future research work and would be useful towards the environmental management of these toxic chemicals.

特大型矿产资源开发与区域经济发展——以西藏玉龙铜矿资源开发为例

矿产资源,特别是特大型矿的开发对区域经济发展具有重要的带动作用。西藏玉龙铜矿在国内仅次于德兴铜矿的特大型矿山,它的开发具有重大战略意义,有利于带动昌都地区经济的发展,本文认为开发玉龙铜矿既面临着矿产资源开发机制、模式及矿产开发区功能与结构等一系列重大变革,又出现许多有利条件和不利因素。必须面向下一世纪和国内外两个市场,按照新的机制,选择融合式发展,努力建立一个综合功能型的昌都地区经济。     

Social and Economic Factors in the Spread of the NIMBY Syndrome against Waste Disposal Sites in Taiwan

The paper analyses the NIMBY syndrome against solid waste disposal sites in Taiwan and argues that the rapid growth of this syndrome has been attributable to three social and economic factors, namely: (1) The awakening of public environmental consciousness; (2) the increase in the value of urban marginal land; and (3) the process of political liberalization and the uprising of so-called 'self-help actions' from the public.

Field measurements of dissociation of ammonium nitrate at a Beijing site

The atmospheric nitric acid, ammonia and ammonium nitrate aerosol was determined simultaneously in a Beijing site to teste quilibrium. Rather good agreement between measurements and theory was found at ambient temperature above 9oC at relative humidity below 70%. Below 9oC the kinetic constraints preventing rapid attainment equilibrium were observed. A procedure for calculation of dependence of NH4NO3 aerosol dissociation constants on temperature and relative humidity was given. The seasonal variation of concentration of NH3, total NH4+ and HNO3 was observed.The seasonal variation of concentration of HNO3 was caused by dissociation of aerosol of NH4NO3. The concentrations of NH3 were 1-2 order higher than those of HNO3. For formation of NH4NO3 aerosol the HNO3 was the control reagent. Any increase of HNO3 to formed from NOx would react with NH3 form NH4NO3 aerosol in Beijing area except for someday in summer time.
