“三线一单”对重构环境准入体系的意义及关键环节

“放管服”背景下以环评为核心的环境准入体系面临工作周期长、制度效率低、结论可验证性差、社会认可度不高等诸多挑战。本文针对“三线一单”具有的早期介入和共享区域基础信息的工作特征,认为将“三线一单”纳入环境准入体系后可以更好地发挥系统性预防作用,提升政府的决策能力和环评工作效率,实现环境准入体系的高质量和高效率。在重构环境准入体系方面,提出了“三线一单”与规划环评和项目环评制度衔接的关键环节:明确三项制度不同的职责定位和责任主体、厘清三项制度的衔接环节,以及完善三项制度间的信息交互。

How do you build back better so no one is left behind? Lessons from Sint Maarten,Dutch Caribbean,following Hurricane Irma

The Sendai Framework for Disaster Risk Reduction 2015–2030 and the United Nations’ Sustainable Development Goals call for action to build back better in ways that leave no one behind. At the same time, ensuring a local voice is increasingly central to humanitarian engagement. These aims contrast with limited analysis of how local actors might be supported in these respects during response and recovery, and how far recommendations are specific or generalisable across richer and poorer national contexts. The paper begins by comparing lessons learnt by survivors and community organisations in Sint Maarten, Dutch Caribbean, following a high‐income state‐led response to Hurricane Irma in 2017 with the priorities of lower income, humanitarian‐led endeavours. The differences reveal the importance of economic resources as the basis for individual self‐reliance and a fragmented civil society with limited leadership ambitions in Sint Maarten. Strong cross‐cultural alignment nevertheless allows for a globally‐relevant and yet contextually‐sensitive framework for survivor‐led action and reconstruction.     

Development of inherent safety and health index for formulated product design

The numerous formulated products which are introduced to the market consist of chemical ingredients that may cause various safety and health hazards to the consumers. Therefore, it is extremely important to practice a systematic methodology to formulate products with acceptable safety and health performances. This work presents an index-based methodology to assess the safety and health hazards of the ingredients during the early formulation stage of product design. Hence, new inherent safety and health sub-indexes are introduced to improve the current safety and health hazards that are needed in formulated product design. The inherent safety and health sub-indexes are assigned with scores based on the degree of potential hazards. A higher score indicates a higher safety risk or severe health effect, and vice versa. The proposed methodology will greatly assist the users to identify the adverse safety and health effects caused by the ingredients. Hence, it is pivotal to eliminate or reduce the safety and health impacts from product usage. A case study on common ingredients used in the formulation of paint is presented on this study to describe the proposed method.     

论中—下扬子“一盖多底”格局与演化

本文是“长江中小下游及邻区构造地质图1／100万”（85－901－03）的研究成果。在区内划分出4种变质基底，结合深部资料确定4个构造—地层地体．讨论了各自组成、历史和相互拼接时代，强调了晚元古代普宁运动在地质发展中的重大意义。认为晋宁运动Ⅰ幕（1000－900Ma）是杨子区内各地体向崆岭—董岭古陆拼贴的增生期．扬子地块形成；晋宁运动Ⅱ幕（800－700Ma）是华北—扬子—华夏地块对接时代．形成古中国大陆。古生代以来为盖层发育阶段。提出中下扬子的“一盖多底”的地壳结构。纵览扬子地块地质发展和演化．可分为四个历史时期：基底发育与古中国大陆形成期；盖层发育与加里东运动；欧亚大陆形成与印支运动；陆缘—板内变形与燕山运动。     

阿司匹林生产用废弃活性炭的微波一步再生

阿司匹林生产过程中会产生大量的粉末状废弃活性炭,对环境造成了较大的影响。提出了不外加活化气体的微波加热一步再生法再生废弃活性炭,使之循环利用。通过试验考察了再生温度、再生时间和物料厚度等因素对再生活性炭吸附性能和得率的影响。在再生温度700℃、再生时间10 min和物料厚度20 mm的优化条件下,亚甲基蓝吸附量为180 mg/g,再生活性炭的得率为40.875%,与常规方法再生药用活性炭相比,降低了再生温度,再生时间缩短了50%左右。此时再生活性炭的比表面积为1 296 m~2/g,平均孔径为3.016nm,适合于吸附亚甲基蓝,总孔体积为0.977 4 m L/g,其中微孔占47.81%,表明微孔和中孔都较为发达。扫描电镜和傅里叶变换红外光谱图分析表明,活性炭孔隙和表面性质得到了有效的再生恢复。微波一步再生法避免了通入活化气体而导致大量粉末活性炭被带走的问题,并且该方法具有速度快、效率高等优势。

Safening activity of natural hydroxamic acids and analogous compounds against herbicide injury to maize

Abstract

Safening activities of natural compounds DIMBOA, DIBOA, and MBOA, as well as synthetic 1,4‐benzoxazin‐3‐ones were tested against acetochlor and EPTC injuries to maize. No safening activities of natural products and from low to moderate activity of synthetic benzoxazinones were observed. In order to explain inefficacy of natural compounds we studied the influence of these molecules on enzymes participating in metabolic detoxication of acetochlor and EPTC. Pretreatment with DIMBOA elevated maize cytochrome P450 levels. Pretreatments with chemicals containing 1,4‐benzoxazin‐3‐one backbone did not alter glutathione S‐transferase enzyme activities. However, all natural products inhibited glutathione S‐transferase activity of roots and shoots in vitro after addition to the enzyme. Safening ineffectiveness of natural hydroxamic acids may be explained by their inhibitory effects on GST enzymes due to their reaction with sulfhydryl groups on the enzyme.
