区域开发的灾害识别和对策

区域开发是当前普遍采用的一种经济发展模式，然而区域开发活动引起的灾害还没有引起足够的重视。该文多区域开发建设活动与区域环境相互影响的观点，介绍了对区域开发引起的灾害进行识别的方法及其对策分析。区域灾害识别可采用历史记录法，成因分析法、预测法等方法。区域灾害对策有非工程性和工程性两类，工程性对策应根据区域灾害的类型、频率、强度、损失及区域开发性质来决定，而非工程性对策中建立区域统一的防灾救灾组织管理     

区域开发生态影响评价方法及应用

建立一套系统的区域生态影响评价方法，对于区域环评和环境的可持续发展具有重要的意义。以济南舜湖社区区域开发为例，建立和应用由生态指标法、图形叠图法、景观生态学方法构成的方法体系，对舜湖社区区域开发生态环境影响进行了评价，并提出生态保护和建设的具体措施。结果表明，3者构成的方法体系，能较全面的反映生态环境质量现状，预测生态环境影响，有较为广泛的应用前景。     

Survey of dioxin sources in the Baltic Region (extended summary)

The present paper summarises the results of the project: 'Survey of Anthropogenic Sources of Dioxins and Furans in the Baltic Region'. As a part of the project, inventories have been carried out in Estonia, Latvia, Lithuania and Poland by applying the toolkit for quantification of dioxin and furan releases developed by UNEP Chemicals. The main route of direct releases to the environment is emission to air. Total emission to air from Poland was estimated at 490 (88-1,300) g I-TEQ/year, whereas the emissions from Estonia, Latvia and Lithuania were estimated as being 14 (2.4-54), 23 (2.6-63) and 17 (2.6-38) g I-TEQ, respectively. In general, the uncertainty on the estimates is very high, and recommendations regarding further development of the inventories have been made, and measures for reducing the releases have been provided.     

"How near were we to Ruine": the effects in England of the earthquake of 8th September 1692

This paper attempts to Illustrate some of the advantages and disadvantages of using contemporary evidence in the study of historical seismicity. The event considered here is doubly significant—it was a large event by British standards, as well as arguably the best documented earthquake to have occurred before the mid-eighteenth century. At a time when an interdisciplinary approach to historical seismicity is still in its infancy this paper identifies those areas where the available sources can assist in the evaluation of early macroseismic data.     

建立和完善环境资源区域补偿制度的对策初探

分析了实施流域内环境资源区域补偿工作存在的主要问题,对制度的实施提出了初步的对策建议：要通过加强立法和制定标准使补偿制度规范化,通过实施公正的监测,建立协调机制和补偿资金测算、营运机制等措施,实现环境利益和经济利益的均衡．     

浅谈汽车内空气污染来源及影响因素

随着中国社会经济的不断发展,人民生活水平的不断提高,汽车已逐渐成为人们日常生活中的一部分。然而在世界的范围内,汽车内的空气污染问题已越来越得到重视,但就国内的情况而言,汽车内的空气污染问题却没有随着汽车的普及而得到人们足够的认识。有见及此,本文指出了造成汽车内空气污染的几种主要污染来源及其有可能产生的危害,同时讲述了影响车内空气质量的几种主要因素,并就此给出了相关污染减轻的建议,希望籍此减少汽车内空气污染对人们健康的危害。     

Characteristics of atmospheric volatile organic compounds in urban area of Beijing: Variations, photochemical reactivity and source apportionment

Atmospheric volatile organic compounds (VOCs) were observed by an on-line gas chromatography-flame ionization detector monitoring system from November 2016 to August 2017 in Beijing. The average concentrations were winter (40.27 ± 25.25 μg/m³) > autumn (34.25 ± 19.90 µg/m³) > summer (32.53 ± 17.39 µg/m³) > spring (24.72 ± 17.22 µg/m³). Although benzene (15.70%), propane (11.02%), ethane (9.32%) and n-butane (6.77%) were the most abundant species, ethylene (14.07%) and propene (11.20%) were the key reactive species to ozone formation potential (OFP), and benzene, toluene, ethylbenzene, m-xylene + p-xylene and o-xylene (54.13%) were the most reactive species to secondary organic aerosol formation potential (SOAFP). The diurnal and seasonal variations indicated that diesel vehicle emission during early morning, gasoline vehicle emission at the traffic rush hours and coal burning during the heating period might be important sources. Five major sources were further identified by positive matrix factorization (PMF). The vehicle exhaust (gasoline exhaust and diesel exhaust) was found to be contributed most to atmospheric VOCs, with 43.59%, 41.91%, 50.45% and 43.91%, respectively in spring, summer, autumn and winter; while solvent usage contributed least, with 11.10%, 7.13%, 14.00% and 19.87%, respectively. Biogenic emission sources (13.11%) were only identified in summer. However, both vehicle exhaust and solvent usage were identified to be the key sources considering contributions to the OFP and SOAFP. Besides, the contributions of combustion during heating period and gasoline evaporation source during warm seasons to OFP and SOAFP should not be overlooked.     

基于双模型的星云湖沉积物重金属溯源及风险评价

为了解星云湖沉积物中重金属污染现状,并为湖区污染防治提供理论依据,通过分析湖区表层沉积物中Cu、Zn、Pb、Ni、Cr、Cd、As、Hg等重金属含量,研究了其风险特征及污染来源组成.结果表明:①仅Ni、Cu含量尚未超过星云湖的背景值,其余元素均出现累积,Hg含量是星云湖背景值的2.13倍,潜在生态风险最高.②星云湖沉积物中重金属的空间分布与入湖河流和湖盆地势相关,表现出由河流输送向湖心扩散的趋势,高浓度区均分布在湖心深水区和特定河口位置,Hg的分布异于其他元素,呈西北湾>南部>中部的特征.③西北湖湾潜在生态风险最高,Cd、As是主要贡献元素.④星云湖沉积物中重金属主要来自自然源（占比为43.32%）、工业源（占比为25.89%）、农业源（占比为20.52%）和交通源（占比为10.27%）.研究显示,星云湖自然源重金属污染贡献最大,人为源相对较低,但湖区重金属污染处于较高水平.星云湖的重金属污染生态风险可能会持续加剧,其中Hg是污染防控的重点.
