  • issues in monitoring Hazardous Chemicals in stormwater runoff discharges from superfund and other Hazardous Chemical sites
    Remediation Journal, 2010
    Co-Authors: Anne Joneslee
    Abstract:

    Deficiencies in design and execution render stormwater-runoff monitoring programs for many Hazardous Chemical sites inadequate for assessing the potential environmental quality and public health impacts of Chemicals in the runoff. Two pervasive problems are the use of analytical methods that are inadequate for measuring certain Hazardous Chemicals at potentially Hazardous concentrations, and the application of “criteria/standards” that are inappropriate for evaluating the environmental/public health impacts of Chemicals. These concerns are most notable for carcinogens and Chemicals that bioaccumulate in edible aquatic organisms, including arsenic, chromium, beryllium, mercury, dioxins, organochlorine pesticides (such as DDT), and polychlorinated biphenyls; unrecognized pollutants; and nanomaterials. In order to appropriately evaluate whether the runoff/discharge from a Hazardous Chemical site is a threat to human health, the analytical methods must be sufficiently sensitive in critical concentration ranges; sampling regimens need to be sufficiently rigorous to provide reliable characterization of the content of the runoff, receiving water, and, for bioaccumulatable Chemicals, levels in edible organisms in receiving water. Proper sampling and analysis will then provide data to enable the appropriate criteria/standards to be applied. © 2010 Wiley Periodicals, Inc.

  • evaluation of surface water quality impacts of Hazardous Chemical sites
    Remediation Journal, 1999
    Co-Authors: Anne Joneslee
    Abstract:

    Common deficiencies in the typical evaluation of the surface water quality impacts of Hazardous Chemical sites are discussed. Particular attention is given to deficiencies in monitoring stormwater runoff, as well as the input of contaminated groundwaters that lead to impairment of the beneficial uses of nearby surface waters because of site-derived Hazardous and deleterious Chemicals. An alternative approach, Evaluation Monitoring, is presented in this paper. Evaluation Monitoring shifts the monitoring program from periodic sampling and analysis of stormwater runoff and ambient waters for a suite of Chemical parameters, to examining the receiving waters to determine what, if any, water quality use impairments are occurring in surface waters due to the runoff-associated constituents and shallow groundwater input.

  • stormwater runoff water quality evaluation and management program for Hazardous Chemical sites development issues
    Superfund risk assessment in soil contamination studies: third volume. Papers presented at the symposium on Superfund risk assessment held at San Dieg, 1998
    Co-Authors: Anne Joneslee
    Abstract:

    The deficiencies in the typical stormwater runoff water quality monitoring from Hazardous Chemical sites and an alternative approach (Evaluation Monitoring) for monitoring that shifts the monitoring program from periodic sampling and analysis of stormwater runoff for a suite of Chemical parameters to examining the receiving waters to determine what, if any, water quality use impairments are occurring due to the runoff-associated constituents is presented in this paper. Rather than measuring potentially toxic constituents such as heavy metals in runoff, the monitoring program determines whether there is aquatic life toxicity in the receiving waters associated with the stormwater runoff. If toxicity is found, its cause is determined and the source of the constituents causing the toxicity is identified through forensic analysis. Based on this information, site-specific, technically valid stormwater runoff management programs can be developed that will control real water quality impacts caused by stormwater runoff-associated constituents.

  • using nanotechnology for the substitution of Hazardous Chemical substances
    Journal of Industrial Ecology, 2008
    Co-Authors: Ulrich Fiedeler
    Abstract:

    Summary It is often assumed that nanotechnology (NT) holds the potential to provide a substantial contribution to the solution of various ecological problems, including high consumption of energy and materials and the generation of waste. However, problems surrounding the use and release of Hazardous substances remain largely unexplored. For this reason, the Scientific Technical Option Assessment (STOA) Panel of the European Parliament initiated a study on “The Role of Nanotechnology in Chemical Substitution.” The subject and aim of the study was an investigation into preexisting and potential applications of NT that could lead to a reduction in Hazardous substances by providing substitutes for them. In terms of method, it was based on electronic searches of the literature, expert interviews, and an expert workshop. This article discusses the results of the project. It focuses on the methodological challenges and the principal problems resulting from a combination of the broad and ill-defined concept of NT and the specific concept of Hazardous substances. The Hazardous substances addressed had to be reduced to a manageable number, and the term substitution was understood according to the characteristics of NT and the way in which the latter could reduce the use of Hazardous substances. Although several applications of NT were identified that could lead to a considerable reduction in the use of Hazardous substances, ambiguities in both the concept of NT and the concept of substitution in relation to NT prevent a comprehensive assessment of the potential of NT in respect to substitution.

  • emergency evacuation of Hazardous Chemical accidents based on diffusion simulation
    Complexity, 2017
    Co-Authors: Jianghua Zhang
    Abstract:

    The recent rapid development of information technology, such as sensing technology, communications technology, and database, allows us to use simulation experiments for analyzing serious accidents caused by Hazardous Chemicals. Due to the toxicity and diffusion of Hazardous Chemicals, these accidents often lead to not only severe consequences and economic losses, but also traffic jams at the same time. Emergency evacuation after Hazardous Chemical accidents is an effective means to reduce the loss of life and property and to smoothly resume the transport network as soon as possible. This paper considers the dynamic changes of the Hazardous Chemicals’ concentration after their leakage and simulates the diffusion process. Based on the characteristics of emergency evacuation of Hazardous Chemical accidents, we build a mixed-integer programming model and design a heuristic algorithm using network optimization and diffusion simulation (hereafter NODS). We then verify the validity and feasibility of the algorithm using Jinan, China, as a computational example. In the end, we compare the results from different scenarios to explore the key factors affecting the effectiveness of the evacuation process.

  • the future of Hazardous Chemical safety in china opportunities problems challenges and tasks
    Science of The Total Environment, 2018
    Co-Authors: Bing Wang, Chao Wu, Genserik Reniers, Lang Huang, Liangguo Kang, Laobing Zhang
    Abstract:

    China is a major country producing and using Hazardous Chemicals. Unfortunately, the Hazardous Chemical industry is still one of the most high-risk industries in China. In recent years, especially after two devastating Hazardous Chemical accidents, namely "Qingdao 11.2 Crude Oil Leaking and Explosion Accident" and "Tianjin Port 8.12 Fire and Explosion Accident" which occurred in 2013 and 2015 respectively, China has attached great importance to Hazardous Chemical safety. The period between 2016 and 2017 is a crucial period for the future direction of Hazardous Chemical safety in China because China released a series of important government documents (such as 'Thirteenth Five-Year (2016-2020) Plan for Hazardous Chemical Safety' and 'Comprehensive Plan for Hazardous Chemical Safety Management (December 2016-November 2019)') to promote Hazardous Chemical safety in the future. What is the future development of China's Hazardous Chemical safety? To answer this question, this paper attempts to briefly analyze and introduce the opportunities, problems, challenges and tasks of the future of safety with Hazardous Chemical industrial activities in China, according to the current situation of Hazardous Chemical safety in China and using the latest government documents and studies. Obviously, this study can provide useful evidence and suggestions for the future of safety management in the Hazardous Chemical industry both within China and in other countries.

  • The Research of Classification Method for Significant Risk of Hazardous Chemical Tanker which in Transit
    2010 International Conference on Optoelectronics and Image Processing, 2010
    Co-Authors: Yongqing Jiang, Dongji Yang, Jingrui Zhao, Bing Wang
    Abstract:

    Accounting to the present situation of China's road transport for dangerous Chemicals, governments at all levels has no specific classification methods of major hazard source for Hazardous Chemicals tanker in transit. In this paper, we use fuzzy comprehensive evaluation method as the theoretical basis, combined with cases of accident and research materials using the fuzzy statistical method to construct the membership, and to get a reasonable classification according to the principle of maximum degree of membership. In selecting evaluation factors we take into account the cause of the accident during transport, process control and consequences of the accident, divide hazard Chemical tankers in transit into four grades through applying the method to the practice, and the classification results accord with the actual situation.

  • time dynamics of emergency response network for Hazardous Chemical accidents a case study in china
    Journal of Cleaner Production, 2020
    Co-Authors: Lei Du, Yingbin Feng, Liyaning Tang, Wei Lu, Wei Kang
    Abstract:

    Abstract Since currently Hazardous Chemical accidents occur frequently around the world, how to build up an effective emergency response network (ERN) for Hazardous Chemical accidents become an urgent issue. Given the truth that previous static ERN research could not reflect the dynamic interaction patterns among actors in emergency response process, this paper studied the emergency response network for Hazardous Chemical accidents from the perspective of temporal dynamics. Jiangsu Xiangshui 3.21 Chemical plant explosion accident, a major Hazardous Chemical accident just happened in March 2019, was selected as a case in this paper. Based on the time slices of the accident emergency response process, the dynamic evolution of emergency response network, organization functions, and organization positions over time were analyzed by social network analysis (SNA). The results revealed the dynamics of emergency response network in the context of centralized administrative systems. Emergency response network became more decentralized over time, rather than centralized; central organization functions varied depending on the response needs in each period; and positions of participants in network changed as time passed. The results also showed that under the centralized administrative systems, public-sector organizations were the core of emergency response network; whilst non-profit organizations and private organizations were largely marginalized. A hybrid network with centralization and decentralization complement each other may be more effective. ERN for Hazardous Chemical accidents should be considered in a time-dynamic way and collaborations among public sector organizations, NPOs and private organizations should be paid more attention to improve the emergency response efficiency. These findings may expand knowledge for researchers and practitioners to understand emergency response network of Hazardous Chemical accidents from dynamic perspectives, having an important significance for reducing and controlling economic losses, social risks and environmental damage caused by Hazardous Chemical accidents.
