中国化工园区雨排系统环境风险防控研究

雨排系统是化工园区重要的基础设施,如果没有建立有效的环境风险防控体系,污染物有可能通过园区雨排系统排入外环境,造成重大环境影响.目前,中国已出台的有关化工园区雨排系统环境风险防控的政策法规缺少强制性和统一性,监管标准缺失导致环保部门缺乏行之有效的监管手段,园区规划阶段协同机制的不健全也增加了后期监管的难度.鉴于目前中国化工园区雨排系统环境风险防控方面存在的问题,建议国家和地方加快监管标准出台,强化相关政策的落实,优化园区雨排系统,实施分类、分级管控,同时加强企业的监管.     

基于熵权模糊模型的土壤重金属生态风险评价

土壤重金属污染评价对于环境保护策略的制定和民众健康的防护具有重要意义。应用熵权、毒性系数和模糊数学构建了熵权模糊法评价模型,并以陕西省彬长煤化工业区为例,对其土壤重金属富集特征和潜在生态风险进行了评估。结果表明,土壤Cd、Co和Pb质量比较高,空间差异明显,建矿时间较长的工业园区土壤重金属潜在生态风险水平较高。熵权评价显示Cd为主要污染因子(权重为0.566)。模糊综合评价显示,研究区55.7%的样点为轻度污染,24.3%的样点为中度污染,无重污染和严重污染隶属样点。研究区污染程度有由轻度污染向中度污染过度的趋势。与传统污染评价指数相比,熵权法和模糊数学模型的联合应用有助于提高风险评价的准确性。     

Young drivers' responses to anti-speeding advertisements: Comparison of self-report and objective measures of persuasive processing and outcomes

Objective: Self-report measures are typically used to assess the effectiveness of road safety advertisements. However, psychophysiological measures of persuasive processing (i.e., skin conductance response [SCR]) and objective driving measures of persuasive outcomes (i.e., in-vehicle Global Positioning System [GPS] devices) may provide further insights into the effectiveness of these advertisements. This study aimed to explore the persuasive processing and outcomes of 2 anti-speeding advertisements by incorporating both self-report and objective measures of speeding behavior. In addition, this study aimed to compare the findings derived from these different measurement approaches.

Methods: Young drivers (N = 20, M age = 21.01 years) viewed either a positive or negative emotion–based anti-speeding television advertisement. While viewing the advertisement, SCR activity was measured to assess ad-evoked arousal responses. The RoadScout GPS device was then installed in participants' vehicles for 1 week to measure on-road speed-related driving behavior. Self-report measures assessed persuasive processing (emotional and arousal responses) and actual driving behavior.

Results: There was general correspondence between the self-report measures of arousal and the SCR and between the self-report measure of actual driving behavior and the objective driving data (as assessed via the GPS devices).

Conclusions: This study provides insights into how psychophysiological and GPS devices could be used as objective measures in conjunction with self-report measures to further understand the persuasive processes and outcomes of emotion-based anti-speeding advertisements.     

Antipoaching standards in onshore hydrocarbon concessions drawn from a Central African case study

Unsustainable hunting outside protected areas is threatening tropical biodiversity worldwide and requires conservationists to engage increasingly in antipoaching activities. Following the example of ecocertified logging companies, we argue that other extractive industries managing large concessions should engage in antipoaching activities as part of their environmental management plans. Onshore hydrocarbon concessions should also adopt antipoaching protocols as a standard because they represent a biodiversity threat comparable to logging. We examined the spatiotemporal patterns of small‐ and large‐mammal poaching in an onshore oil concession in Gabon, Central Africa, with a Bayesian occupancy model based on signs of poaching collected from 2010 to 2015 on antipoaching patrols. Patrol locations were initially determined based on local intelligence and past patrol successes (adaptive management) and subsequently with a systematic sampling of the concession. We generated maps of poaching probability in the concession and determined the temporal trends of this threat over 5 years. The spatiotemporal patterns of large‐ and small‐mammal poaching differed throughout the concession, and likely these groups will need different management strategies. By elucidating the relationship between site‐specific sampling effort and detection probability, the Bayesian method allowed us to set goals for future antipoaching patrols. Our results indicate that a combination of systematic sampling and adaptive management data is necessary to infer spatiotemporal patterns with the statistical method we used. On the basis of our case study, we recommend hydrocarbon companies interested in implementing efficient antipoaching activities in their onshore concessions to lay the foundation of long‐needed industry standards by: adequately measuring antipoaching effort; mixing adaptive management and balanced sampling; setting goals for antipoaching effort; pairing patrols with large‐mammal monitoring; supporting antipoaching patrols across the landscape; restricting access to their concessions; performing random searches for bushmeat and mammal products at points of entry; controlling urban and agricultural expansion; supporting bushmeat alternatives; and supporting land‐use planning.     

Considering connections between Hollywood and biodiversity conservation

Cinema offers a substantial opportunity to share messages with a wide audience. However, there is little research or evidence about the potential benefits and risks of cinema for conservation. Given their global reach, cinematic representations could be important in raising awareness of conservation issues and species of concern, as well as encouraging greater audience engagement due to their heightened emotional impact on viewers. Yet there are also risks associated with increased exposure, including heightened visitor pressure to environmentally sensitive areas or changes to consumer demand for endangered species. Conservationists can better understand and engage with the film industry by studying the impact of movies on audience awareness and behavior, identifying measurable impacts on conservation outcomes, and engaging directly with the movie industry, for example, in an advisory capacity. This improved understanding and engagement can harness the industry's potential to enhance the positive impacts of movies featuring species, sites, and issues of conservation concern and to mitigate any negative effects. A robust evidence base for evaluating and planning these engagements, and for informing related policy and management decisions, needs to be built.     

A rising tide raises all boats: Regional promotion of process safety through joint government/industry management

With the development of increasingly complex processes and technologies in chemical and manufacturing industries, Process Safety Management (PSM) has been globally recognized as the primary tool for operating companies to reduce process accidents on their industrial sites and the risks posed to their employees and surrounding communities. Yet, industrial facilities are often interdependent and collocated with others. Recognizing this, regional authorities are also applying PSM principles to reduce the cumulative incidents associated with high density industrial areas and the multiplicative risks posed to broader communities. This paper compares Strathcona County Emergency Service (SCES) in Alberta, Contra Costa County Health Service Hazard Material Programs (CCCHSHMP) in California, and Technical Standards & Safety Authority (TSSA) in Ontario and their PSM systems to provide practical recommendations to improve SCES's system. Four aspects of PSM are considered: regulation and guidance, auditing and inspection, annual performance indicators, and public participation. Based on the results of this comparison, we recommend that SCES develop comprehensive PSM regulations based on CSA Z767-17 PSM including clear instructions for assessing technologies and methodologies for consequence analysis. Both worst-case scenarios and alternative scenarios need to be considered as well as the domino effect of primary accidents. Furthermore, regular audits and inspections will ensure compliance with PSM regulations while helping the design of planning, performing, and following-up strategies to ensure effectiveness. In addition, we suggest the use of lagging and leading performance indicators to evaluate the performance of the PSM program. Finally, we recommend using advisory councils or commissions to increase public participation and ensure the representation of stakeholders' perspectives with the PSM system.     

Eco‐efficiency,self‐sufficiency and sustainability in transport: The limits for Brazilian sugarcane ethanol policy

This paper examines the historic development of the Brazilian sugarcane ethanol sector and the largely successful attempt to create a sustainable, renewable fuel for the transport sector. The policy that resulted from this process is an example of meeting the need for sustainable transport through the consideration of location‐specific characteristics and appropriate policy. The paper then questions the current and expected trajectory of the sugarcane ethanol sector with the focus on one key question: can sustainability be exported? In this analysis, the paper identifies new threats to the sustainability of Brazilian sugarcane ethanol and potential “opportunity costs” incurred in further development and internationalization of the sector. The paper concludes that exporting sugarcane ethanol may bring unanticipated deleterious consequences, which in turn means that both policy and theory need to be more precise about how sustainable transport is defined and bounded by time and space.
