A review of international practice in the design of voluntary Pollution Prevention Programs

Voluntary approaches to industry-wide pollution prevention programs have gained a global impetus. Despite this impetus relatively little research has been undertaken into identifying key features of successful programs. This research identified these features by reviewing selected programs in five countries, Australia, Canada, Japan, the United Kingdom and the United States. Nine key features have been identified, namely: Adequate and consistent funding; Collaborative relationship with industry; Single sector program focus; Setting credible goals; Info-regulation and resources available; Threat of credible enforcement; Regular and credible monitoring; Visible participant benefits; and, Transparent provision of program results. The research complements other work and while showing a high level of similarity in the features, provided also for the inclusion of two further design features, namely ‘adequate and consistent funding’, and developing a maintaining a ‘collaborative relationship with industry’. It is suggested that the nine design features alone, while important, are insufficient and that further research is required to identify these other supporting factors.     

人工纳米材料对贝类生态毒理效应的研究进展

纳米技术已成为21世纪发展最迅猛的技术领域之一。纳米材料因其具备新异的物理、化学特性而广泛应用于各种领域,包括农业,电子工业,生物医学,制造业,医药品和化妆品等,因此纳米颗粒不可避免会释放到水环境中。贝类由于其具有分布广,处于食物链中的关键位置,滤食食性,对重金属及污染物有较强的生物累积能力,且很多贝类具有养殖和商业价值,因而纳米颗粒对贝类的生态毒性效应备受关注。本文通过对已有相关研究成果进行归纳分析,重点阐述了3方面的内容:1)人工纳米材料在水环境中的行为;2)贝类作为水生污染监测指示生物的重要意义;3)人工纳米材料对贝类的毒性效应,主要包括贝类对纳米颗粒摄取、积累和转移,并从组织细胞水平,分子和基因水平,胚胎发育和个体生长水平等阐述了纳米材料对贝类的毒性效应。     

海洋酸化对鱼类感觉和行为影响的研究进展

海洋酸化是指大气增多的二氧化碳(CO2)溶解于海水而导致海水p H值降低的过程。海洋酸化将改变海水碳酸盐平衡体系,使依赖于原化学环境的多种海洋生物乃至生态系统面临巨大威胁。海洋酸化对钙质生物影响的研究最早引起大家关注,而海洋鱼类具有较完善的酸碱调节机制,大家普遍认为酸化对其影响不大。但在过去的5年中,不少实验证明海洋酸化会影响海洋鱼类仔稚鱼的感觉和行为,减弱其野外的生存能力及增加被捕食率,很可能将威胁自然种群补给量和影响全球的渔业资源量。本文从嗅觉、听觉、视觉及高级意识和相关行为角度,综述近几年海洋酸化对鱼类感觉和行为影响的研究进展,介绍了鱼类神经行为生物学的研究,为全面了解和预测海洋酸化的生态、经济和社会效应提供科学依据。     

海洋放射性污染生态风险评价研究进展

近年来,随着我国核电事业迅猛发展,海洋放射性污染的风险激增,放射物质的事故性污染将成为海洋环境一个重要问题。目前,海洋环境放射性污染风险评估的研究仍然较为薄弱,开展海洋放射性污染生态风险评价有助于了解事故对海洋生态的危害程度,为海洋与海岸带环境管理提供科学决策依据,维护海洋生态系统的健康与安全。梳理总结当前国内外海洋放射性污染生态风险评价的相关研究进展,结果表明:目前国内外对海洋放射性污染生态风险评价尚未做出科学的定义;现有海洋放射性污染生态风险评价的技术路线大体可归纳为基于经典风险评估框架和基于迭代的生态风险评价框架2种类型;ERICA Tool模型以及RESRAD-BIOTA模型是目前放射性风险评价中应用最多的方法 ,但存在海洋放射性污染标准限值少的问题;现有的研究主要集中于评估事故中后期均衡条件下的长期慢性暴露评价,对事故初期的高剂量、短期急性暴露的风险影响研究较少;我国海洋放射性污染的生态风险评价与环境影响评价的概念混淆,至今没有明确的海洋放射性污染生态风险评价的概念及技术框架。

河流生态系统指示生物与生物监测:概念、方法及发展趋势

综述了河流生物监测的概念、常用指示生物与监测指标、国外相对完善的技术体系及发展趋势。大型底栖动物、着生藻类、鱼类是河流生物监测中最常使用的指示生物,可以单独使用,也可结合使用,详述了这些类群在河流生态系统中的重要地位及用于生物监测的优点。常用的监测指标包括生物多样性指数、生物指数、多参数指数、多变量指数及功能性指数。许多国家和地区(如英国、美国、欧盟等)都已经将生物监测纳入水环境管理系统,并开发出自己的技术体系。未来的河流生物监测中,功能性指数的应用会越来越多,分子技术的介入也会为提高分类辨识度和检测遗传多样性提供更为有效的途径。最后,思考并总结了国内河流生物监测的现状及趋势。     

On the Field of Environmental Communication: A Systematic Review of the Peer-Reviewed Literature

The field of environmental communication has reached several milestones since the 1990s, particularly the establishment of environmental communication-related divisions at professional associations and the founding of the journal Environmental Communication in 2007. This systematic review characterizes the peer-reviewed literature on environmental communication to date, examining methods, geography, top-cited articles, and analyzing keyword and titles. Drawing on the Web of Science Core Collection, which archives the Social Sciences Citation Index and the Arts & Humanities Citation Index, the review finds that attention to environmental communication has exploded in recent years and that the field is methodologically open-minded. Scholars have shifted focus from general environmental risk to specifically climate change in the last decade. Implications for the field are discussed.     

Conservation perspectives of small-scale private forest owners in Europe: A systematic review

Private forest owners are the main forest ownership group within Europe, and important conservation values have been found on their land. Yet, small plot sizes, societal heterogeneity, and structural changes impede developing and implementing effective conservation programs in private forests. We present a systematic literature review focusing on small-scale private forest owners and their perspectives on nature conservation by synthesizing research approaches, social-ecological drivers, and policy recommendations. Conservation perspectives were positively related to female gender, higher levels of education, formalized forest management, an active relation to the forest, and ecological values of the property. In contrast, high age, rural orientation, economic forest management factors, large parcel size, and economic and sentimental property values negatively influenced conservation perspectives. Applying a natural resource conflict management framework, we synthesized recommendations covering three dimensions: substance, procedure, relationship. Considering perspectives of small-scale private forest owners in current forestry decision-making has great potential to strengthen sustainable forest management that integrates nature conservation and resource use.Supplementary InformationThe online version contains supplementary material available at 10.1007/s13280-021-01615-w.
