Insight of chemical environmental risk and its management from the vinyl chloride accident

《环境科学与工程前沿（英文）》 2023年第17卷第4期 doi: 10.1007/s11783-023-1652-x

摘要： The combustion of vinyl chloride (VC) after the train derailment accident in Ohio, USA in February, 2023 has caused widespread concern around the world. This paper tried to analyze several issues concerning the accident, including the appropriateness of the VC combustion in the emergency response in this accident, the meanings of so-called “controlled combustion”, the potential environmental risks caused by VC and combustion by-products, and follow-up work. In our view, this accident had surely caused environmental and health risks to some extent. Hence, a comprehensive environmental risk assessment is necessary, and then the site with risk should be comprehensively remediated, hazardous waste should be harmlessly treated as soon as possible. Finally, this accident suggests that further efforts should be taken to bridge the gap between chemical safety management and their environmental risk management.

Bing ZHANG, Jun BI, Beibei LIU

《环境科学与工程前沿（英文）》 2009年第3卷第2期页码 210-220 doi: 10.1007/s11783-009-0014-7

摘要： Small- and medium-sized enterprises (SMEs) play an important role in sustainable development not only for their significant contribution to China’s economy, but also for their big share of total discharged pollutants. Therefore, this research takes the enterprises in Suzhou Industrial Park, China as the case study to investigate the environmental management practices of SMEs, and identify drivers and barriers to engaging businesses in environmental management initiatives. It is shown that, as in other countries, SMEs are less active in adopting environmental management initiatives than larger companies. Legislation remains the key driver to engage SMEs in environmental management initiatives. Based on the analysis, policy recommendations are also presented.

HUANG Kai, GUO Huaicheng, LIU Yong, ZHOU Feng, YU Yajuan, WANG Zhen

《环境科学与工程前沿（英文）》 2008年第2卷第2期页码 157-162 doi: 10.1007/s11783-008-0011-2

摘要： Water environmental planning and management has become essential for guiding the water pollution control activities. Past water pollution control activities have been site specific, with little thought on water quality standard reaching at the watershed scale. Based on the watershed approach, a seven-step methodological framework for water environmental planning and management was developed. The framework was applied to water environmental planning and management of the Lake Qilu watershed in Yunnan Province, China. Results show that the reduction amount of total nitrogen (TN) under the plan is 1,205 tons per year so that the target of environmental capacity can be reached in 2020. Compared with traditional methods, the framework has its prevalence and could be generalized to analogous watersheds.

Zhenling CUI, Zhengxia DOU, Hao YING, Fusuo ZHANG

《农业科学与工程前沿（英文）》 2020年第7卷第1期页码 14-20 doi: 10.15302/J-FASE-2019295

摘要：

Balancing crop productivity with resource use efficiency and beneficial environmental consequences is essential for sustainable agricultural development worldwide. Various strategies and approaches have been proposed and debated, but turning the concept into management practices in the field with measurable outcomes over several scales remains a challenge. An innovative approach, Integrated Soil-Crop System Management (ISSM), for producing more grain with greater nutrient use efficiencies and less environmental pollution is presented. The ISSM approach has been used in China, in field experiments as well as in thousands of farmer fields, to substantially increase the yields of maize, rice and wheat while simultaneously increasing nitrogen use efficiency and reducing environmental footprints. The scientific principle, implementation strategy and procedures of ISSM are discussed and examples of its demonstrated successes at local and regional levels across China are given. Perspectives for further development of ISSM and expanding its potential impact are also proposed and discussed.

CHANG Miao, PENG Lijuan, WANG Shiwen

《环境科学与工程前沿（英文）》 2008年第2卷第2期页码 172-177 doi: 10.1007/s11783-008-0032-x

摘要： The establishment of the environmental management system in the financial sector can be effectively promoted through the introduction of the environmental protection concept and its implementation by the financial sector. The impact of a sustainable development system on the sector is analyzed in this article from three aspects: environmental risk assessment, financing support for environmental protection projects, and financial services to environmentally friendly corporations and individuals. Influential factors on the development of the environmental management system in China’s financial sector are discussed from the perspective of various entities such as financial institutions, financial regulation authorities, environmental protection departments, corporations, and the public. It is pointed out that China’s financial sector is now in the transitional phase from a defensive attitude to a preventive attitude. Strengthening governmental guidance, the supervision of regulators as well as public awareness of environmental protection should be used to enhance the initiative in the development of the environmental management system in the Chinese financial sector.

An overview of the environmental finance policies in China: retrofitting an integrated mechanism forenvironmental management

LI Wei,HU Mengze

《环境科学与工程前沿（英文）》 2014年第8卷第3期页码 316-328 doi: 10.1007/s11783-014-0625-5

摘要： Considering the significant roles of the policies in developing environmental finance, an overview is conducted on the environmental finance policies (EFPs) in China. This paper analyzed the definition, scope, evolution and main instruments of EFPs. The implementation progress of financial activities on each instrument are investigated respectively. Then the experiences learned from and failures discovered in the development of the EFPs are discussed well recommendations for further improvement of the EFPs and their implementation are provided. Our study found that the EFPs have been established in China after a four-phase evolution since the early 1980s. The policies have played a critical role in leading to a rapid development in environmental finance by involving more financial instruments to accomplish the objective-led environmental plans. Driven by the policies, the new green credit (GC), green security (GS), and green insurance (GI) instruments have been phased in as supplements to the conventional command and control approaches to improve the environmental governance of financial activities and pollution sources. However, the market mechanism of financial institution is limited due to their defensive and incapable performance on implementation some of EFP instruments. To further strengthen the effectiveness of EFPs in facilitating environmental management, recommendations are made mainly on the aspects including developing more specific policy guidelines, enhancing information sharing and disclosure, providing sufficient economic incentives, establishing environmental liabilities with financial activities, and involving issues related to climate change, and biodiversity and ecosystem service.

SPATIOTEMPORAL VARIATION OF WATER QUALITY AND ALGAL BIOMASS IN ERHAI LAKE AND ITS ENVIRONMENTAL MANAGEMENT

《农业科学与工程前沿（英文）》 2023年第10卷第4期页码 566-578 doi: 10.15302/J-FASE-2023520

摘要：

Elucidating the spatiotemporal pattern of water quality and algal biomass is crucial for accurately tracing pollution sources and reducing the risk of algal blooms in lake systems. This study analyzed the spatiotemporal variability of water quality and algal biomass in Erhai Lake from 1994 to 2021 using water quality index (WQI), Mann-Kendall test and Sen’s slope combined methods. The potential causes of water quality deterioration and algal biomass dynamics were also elucidated. The results showed that the historical changes in the water environment of Erhai Lake mainly had three stages: satisfactory (1994‒2001), deteriorating (2002‒2010) and improving (2011‒2021). The changes in water quality and algal biomass were primarily affected by total nitrogen, total phosphorus and chemical oxygen demand in different stages. The water environment of Erhai Lake is currently improving significantly, starting in the southern area that is furthest from the sources of agricultural pollution, especially in summer and autumn. This is attributed to the implementation of control measures resulting in lower pollutant loads at particular times and places. Therefore, it is necessary to continue to promote standardized livestock farming, to strengthen rural wastewater collection and to investigate measures such as the interruption of the endogenous cycle.

Managing nutrient for both food security and environmental sustainability in China: an experiment for

Fusuo ZHANG, Zhenling CUI, Weifeng ZHANG

《农业科学与工程前沿（英文）》 2014年第1卷第1期页码 53-61 doi: 10.15302/J-FASE-2014006

摘要： The challenges of how to simultaneously ensure global food security, improve nitrogen use efficiency (NUE) and protect the environment have received increasing attention. However, the dominant agricultural paradigm still considers high yield and reducing environmental impacts to be in conflict with one another. Here we examine a Three-Step-Strategy of past 20 years to produce more with less in China, showing that tremendous progress has been made to reduce N fertilizer input without sacrificing crop yield. The first step is to use technology for in-season root-zone nutrient management to significantly increase NUE. The second is to use technology for integrated nutrient management to increase both yield and NUE by 15%–20%. The third step is to use technology for integrated soil-crop system management to increase yield and NUE by 30%–50% simultaneously. These advances can thus be considered an effective agricultural paradigm to ensure food security, while increasing NUE and improving environmental quality.

The role of EcoCampus in addressing sustainability in UK universities

Peter REDFERN, Hua ZHONG

《工程管理前沿（英文）》 2017年第4卷第2期页码 193-200 doi: 10.15302/J-FEM-2017038

摘要： Universities are key drivers of sustainable development and are well-positioned to contribute to the sustainability agenda. Universities in the United Kingdom (UK) are themselves large and influential organisations, and because of their size, can have a significant impact on the environment. Their challenge, however, is to practice what they preach and to manage their own estates and procurement decisions to reduce their impact on the environment and meet carbon reduction targets. In the UK, higher education (HE) sector Scopes 1 and 2 carbon CO e emissions have, over recent years, been falling considerably short of the emission reduction targets set by the Higher Education Funding Council for England (HEFCE) in all but a few institutions. Setting sector specific targets, therefore, does not guarantee success in addressing climate change. However, in those institutions adopting the EcoCampus management system approach, Scopes 1 and 2 carbon CO e emissions have fallen by up to 5% over the latest reporting period (2013/2014–2014/2015). This contrasts with the increase in emissions from those institutions who currently do not have a certified management system and are currently at the bottom of the People and Planet University League Table. (This is an independent league table of UK universities ranked by environmental and ethical performance). Environmental management systems (EMSs) are increasingly being used by organisations to improve their environmental performance. EMSs deliver many benefits such as reducing resource use and pollution, complying with relevant environmental legislation, managing risks, improving corporate reputation and saving costs. The aim of this research was to assess the carbon management performance of universities in the UK and China and relate this to the level of uptake of EMSs in these universities. The results of this research informed the development of the EMS support and awards programme called EcoCampus. EcoCampus addresses the challenges faced by universities in reducing their carbon emissions by developing an EMS in simple stages with support in a variety of different forms. This self-financing programme has now been operating successfully for over ten years. During this time, EcoCampus has worked with over 60 universities and colleges in the UK. Eighteen participants have currently achieved the highest phase of EcoCampus and certification to the international EMS standard ISO14001. There are currently 40 universities, one research institute and three colleges enrolled on the various phases of the EcoCampus programme. There are five universities from the Russell Group including Cambridge University, Imperial College London, Nottingham University, Newcastle University and University College London. The EcoCampus programme is highly successful in the UK and there is growing interest from international universities wishing to join the programme. Seven of the top ten universities in the UK’s People and Planet University League Table are EcoCampus members. All the top ten universities in the League Table have shown a reduction in their carbon emissions. In contrast, the ten institutions at the bottom of the League don’t have a certified EMS and have increased their carbon emissions. By identifying the benefits of an EMS, particularly in relation to carbon management, it is hoped that this paper will encourage organisations to develop, implement and operate an EMS. This should lead to a more sustainable sector able to lead by example.

《环境科学与工程前沿（英文）》 2008年第2卷第3期页码 318-325 doi: 10.1007/s11783-008-0033-9

摘要： Environmental risk of high sulfur gas field exploitation has become one of the hot spots of environmental management studies. Severe gas HS blowout accidents in recent years have shown that poor understanding and estimates of the poisonous gas movement could lead to dangerous evacuation delays. It is important to evaluate the real concentration of HS, especially in complex terrain. Traditional experiential models are not valid in the case of rough terrain, especially in low-lying areas where the gas accumulates. This study, using high sulfur content gas field of Sichuan “Pu Guang gas field” as study object and adopting objective diagnosis of wind field of land following coordinate three dimensions, applied Lagrangian Puff Model and breaking up technique of puffs to simulate the HS diffusion condition of blowout accidents produced in the high sulfur content gas field of complex terrain area. The results showed that the HS distribution did not occur mainly in low wind direction, and due to the obstruction of the mountain’s body, it accumulated in front of mountain on produced turn over, flowed around submitted jumping type distribution. The mountain waist near the hilltop and low hollow river valley site rapture points simulating contrast showed that the higher the rapture point, the better the diffusing condition of pollutant, the distribution of risk sensitive point decided piping rupture environmental risk size combining the HS diffusion result and residential area dispersing in the study area, synthetic judge located in the high rapture point environmental risk was smaller than the low hollow point, thus it was suggested to carryout laying of lining build of equal high line of higher terrain. According to simulation results, the environmental risk management measures aimed at putting down adverse effects were worked out.

摘要： The homogeneous risk characteristics within a sub-area and the heterogeneous from one sub-area to another are unclear using existing environmental risk zoning methods. This study presents a new zoning method by determining and categorizing the risk characteristics using the -means clustering data mining technology. The study constructs indices and develops index quantification models for environmental risk zoning by analyzing the mechanism of environmental risk occurrence. We calculate the source risk index, air risk field index, water risk field index, and target vulnerability of the study area with Nanjing Chemical Industrial Park using a 100 m × 100 m mesh grid as the basic zoning unit, and then use -means clustering to analyze the environmental risk in the area. We obtain the optimal clustering number with the largest average silhouette coefficient by calculating the average silhouette coefficients of clustering at different -values. The clustering result with the optimal clustering number is then used for the environmental risk zoning, and the zoning result is mapped using the geographic information system. The study area is divided into five sub-areas. The common environmental risk characteristics within the same sub-area, as well as the differences between sub-areas, are presented. The zoning is helpful in risk management and is convenient for decision makers to distribute limited resources to different sub-areas in the design of risk reducing intervention.

《环境科学与工程前沿（英文）》 2013年第7卷第5期页码 658-668 doi: 10.1007/s11783-013-0546-8

摘要： Urban wastewater infrastructures have been threatened by natural and socioeconomic disturbances. This study investigates infrastructure resilience against the risks of long-term changes rather than natural disasters. Urban expansion that leads to an increased urban runoff and massive population movements that cause fluctuations in domestic emissions are considered in this study. Pollution permits for water bodies are adopted as constraints on wastewater infrastructures. A land use-based accounting method, combined with a grid-based database, is developed to map domestic discharge and urban runoff to service areas of wastewater treatment plants. The results of a case study on downtown Sanya, the most famous seashore tourist attraction in China, show that the average resilient values of three sub-catchment areas in 2010 were -0.57, 0.10 and 0.27, respectively, a significant spatial variation. The infrastructure in the Sanya River sub-region is the least flexible, and is more likely to fail due to unstable inflows. The resiliencies will increase to 0.59, 1.01 and 0.54, respectively, in 2020, a considerable improvement in robustness. The study suggests that infrastructure resilience needs to be taken into further consideration for urban planning and the related realm of urban governance to foster more robust wastewater management under various risks.

An approach to calculating allowable watershed pollutant loads

Yu GUO, Haifeng JIA

《环境科学与工程前沿（英文）》 2012年第6卷第5期页码 658-671 doi: 10.1007/s11783-012-0446-3

摘要： To improve the management of discharge pollutants loads in the reservoirs’ watershed, an approach of the allowable pollutants loads calculation and its allocation, based on the water environment model, was proposed. Establishment of the approach framework was described at first. Under the guidance of this framework, two major steps were as follows: modeling and scenario analysis were involved and should be applied to support the decision of discharge loads management; Environmental Fluid Dynamic Code (EFDC) model was selected as the kernel model in this framework. In modeling step, spatial discretization for establishing cell map in model, data preprocessing, parameter calibration and uncertainty analysis (which is considered as the significantly relevant factor of the margin of safety (MOS)), were conducted. As a result of the research, the model-based approach presented as a combination of estimation and precise calculation, which contributed to scenario analysis step. Some integrated modules, such as scenario simulation, result analysis and plan optimization were implemented as cycles in the scenario analysis. Finally, allowable pollutant loads under various conditions were calculated. The Chaihe Reservoir in Liaoning Province, China was used as a case study for an application of the approach described above. Results of the Chaihe reservoir water quality simulation, show good agreement with field data and demonstrated that the approach used in the present study provide an efficient and appropriate methodology for pollutant load allocation.
