More than merely wicked : regulating sewage discharges and other unspeakable problems in environmental policy-making and planning

While the communicative turn in policy-making has encouraged the public deliberation of policy decisions it has arguably had a more limited impact on the ability of public processes to deal with wicked problems. Wicked policy problems are characterised by high levels of complexity, uncertainty and divergence of values. However, some wicked problems present the additional challenge of high levels of psychosocial sensitivity and verbal proscription. Because these unspeakable policy problems frequently involve a significant moral dimension, the regulation of intimate processes or bodies, and strong elements of abjection and symbolic pollution they are quite literally problems that we don’t like to think about or talk about. However, the potential environmental and social impacts of these problems require that they be addressed. In this paper I present the preliminary findings of a research project focussed on the idea of the unspeakable policy problem and how its unspeakable nature can impact upon public participation and policy and environmental outcomes.

Concentration levels of heavy metals and polycyclic aromatic hydrocarbons in car parks at Queensland University of Technology

This study investigates the level of pollutants (polycyclic aromatic hydrocarbons (PAHs) and heavy metals) in three car parks at QUT, one at Kelvin Grove campus and two at the Gardens Point campus. In addition, comparisons between site designs were assessed to identify the possible sources of heavy metals and PAHs. The main contributing source for heavy metals was identified to be from vehicle debris and emissions, while the source of PAHs was identified to be from petrol and diesel engine vehicle emissions. The highest concentration of pollutants was typically found for the 63 micro meter dust samples, proposed to be due to increased surface areas and thus available adsorption sites.

Modeling Environmental Stress

The word stress when applied to ecosystems is ambiguous. Stress may be low-level, with accompanying near-linear strain, or it may be of finite magnitude, with nonlinear response and possible disintegration of the system. Since there are practically no widely accepted definitions of ecosystem strain, classification of models of stressed systems is tenuous. Despite appearances, most ecosystem models seem to fall into the low-level linear response category. Although they sometimes simulate systems behavior well, they do not provide necessary and sufficient information about sudden structural changes nor structure after transition. Dynamic models of finiteamplitude response to stress are rare because of analytical difficulties. Some idea as to future transition states can be obtained by regarding the behavior of unperturbed functions under limiting strain conditions. Preliminary work shows that, since community variables do respond in a coherent manner to stress, macroscopic analyses of stressed ecosystems offer possible alternatives to compartmental models.

Optical Remote Sensing of Coastal Habitats, Moss Landing, California, 9-11 January, 2006: workshop proceedings

The Alliance for Coastal Technologies (ACT) Workshop on Optical Remote Sensing of Coastal Habitats was convened January 9-11, 2006 at Moss Landing Marine Laboratories in Moss Landing, California, sponsored by the ACT West Coast regional partnership comprised of the Moss Landing Marine Laboratories (MLML) and the Monterey Bay Aquarium Research Institute (MBARI). The "Optical Remote Sensing of Coastal Habitats" (ORS) Workshop completes ACT'S Remote Sensing Technology series by building upon the success of ACT'S West Coast Regional Partner Workshop "Acoustic Remote Sensing Technologies for Coastal Imaging and Resource Assessment" (ACT 04-07). Drs. Paul Bissett of the Florida Environmental Research Institute (FERI) and Scott McClean of Satlantic, Inc. were the ORS workshop co-chairs. Invited participants were selected to provide a uniform representation of the academic researchers, private sector product developers, and existing and potential data product users from the resource management community to enable development of broad consensus opinions on the role of ORS technologies in coastal resource assessment and management. The workshop was organized to examine the current state of multi- and hyper-spectral imaging technologies with the intent to assess the current limits on their routine application for habitat classification and resource monitoring of coastal watersheds, nearshore shallow water environments, and adjacent optically deep waters. Breakout discussions focused on the capabilities, advantages ,and limitations of the different technologies (e.g., spectral & spatial resolution), as well as practical issues related to instrument and platform availability, reliability, hardware, software, and technical skill levels required to exploit the data products generated by these instruments. Specifically, the participants were charged to address the following: (1) Identify the types of ORS data products currently used for coastal resource assessment and how they can assist coastal managers in fulfilling their regulatory and management responsibilities; (2) Identify barriers and challenges to the application of ORS technologies in management and research activities; (3) Recommend a series of community actions to overcome identified barriers and challenges. Plenary presentations by Drs. Curtiss 0. Davis (Oregon State University) and Stephan Lataille (ITRES Research, Ltd.) provided background summaries on the varieties of ORS technologies available, deployment platform options, and tradeoffs for application of ORS data products with specific applications to the assessment of coastal zone water quality and habitat characterization. Dr. Jim Aiken (CASIX) described how multiscale ground-truth measurements were essential for developing robust assessment of modeled biogeochemical interpretations derived from optically based earth observation data sets. While continuing improvements in sensor spectral resolution, signal to noise and dynamic range coupled with sensor-integrated GPS, improved processing algorithms for georectification, and atmospheric correction have made ORS data products invaluable synoptic tools for oceanographic research, their adoption as management tools has lagged. Seth Blitch (Apalachicola National Estuarine Research Reserve) described the obvious needs for, yet substantial challenges hindering the adoption of advanced spectroscopic imaging data products to supplement the current dominance of digital ortho-quad imagery by the resource management community, especially when they impinge on regulatory issues.

Rhythms of division of some algae in situ and in laboratory culture. [Translation from: Studii Cerc.Biol.(Bot.) 21, 61-65, 1969. ]

The rhythm of division of 9 species belonging to different groups of algae were analysed in situ and in the laboratory. The research which developed in different environmental conditions attempted to establish the capacity for multiplication and assimilation of chlorophyll on the part of the algae under study with a view to placing them in a culture. The results obtained showed that the green multicellular algae (eg. Ulothrix) and the blue algae (eg. Lyngbya, Oscillatoria) are able to produce an appreciable quantity of dry matter, just as the unicellular algae. At the same time it arises that amongst the numerous factors of the environment, temperature plays one of the most important roles in the process of multiplication.

Confiabilidade Metrológica: o caso da análise de DQO em um laboratório acadêmico.

Desde 2004, o CONAMA (Conselho Nacional de Meio Ambiente), através de sua Resolução n 344, vem exigindo que as análises físicas, químicas e biológicas em matrizes ambientais sejam realizadas em laboratórios ambientais que possuam sua competência técnica reconhecida formalmente através da acreditação concedida pelo Inmetro. Assim, algumas Unidades Federativas vem adotando o mesmo critério para cadastramento de laboratórios em seus bancos de dados. Com isso, houve um crescimento no número de acreditações: em 2002 haviam 12 laboratórios acreditados e em 2012 foram concedidas 198 acreditações a laboratórios ambientais. A adoção da ABNT NBR ISO/IEC 17025 como padrão de trabalho, além de atender as legislações vigentes, possui as seguintes vantagens: satisfação do cliente, credibilidade e melhoria contínua do laboratório, melhoria da capacitação profissional e a conquista de um mercado mais amplo. Buscando adequar-se a essa realidade, apesar de todas as dificuldades inerentes ao processo de implementação dos requisitos da ABNT NBR ISO/IEC 17025 em laboratórios universitários e de pesquisa, o Laboratório de Engenharia Sanitária (LES/DESMA) priorizou a adequação da determinação da demanda química de oxigênio (DQO) aos requisitos técnicos da ABNT NBR ISO/IEC 17025:2005, por ser um parâmetro indicador global de matéria orgânica em águas residuárias e superficiais e ser amplamente utilizado no monitoramento de estações de tratamento de efluentes líquidos e pelo fato deste poder ser determinado por duas técnicas analíticas distintas: espectrofotometria e colorimetria. Em razão deste cenário, o objetivo deste trabalho foi avaliar o desempenho dos métodos 5220 B e 5220 D descritos pelo Standard Methods, através dos parâmetros de validação de métodos analíticos. Ambos os métodos mostraram-se adequados ao uso a que se destinam e o limite de quantificação determinado apresentou-se compatível com o praticado com os laboratórios acreditados. As incertezas foram calculadas de forma a quantificar a qualidade do resultado.

Gestão de resíduos químicos em laboratório universitário. Estudo de caso: Laboratório de Engenharia Sanitária, Faculdade de Engenharia UERJ.

Ao longo da história do homem, as universidades têm exercido um papel fundamental na geração de conhecimentos e tecnologias com o fim maior de melhorar a qualidade de vida de nossa sociedade. Em contrapartida, além de produzir os benefícios oriundos da aplicação dos conhecimentos e tecnologias, as pesquisas científicas produzem também diversos tipos de resíduos potencialmente poluidores e tóxicos os quais não estão sendo descartados e tratados corretamente. A falta de políticas institucionais de gerenciamento de resíduos nas universidades além de proporcionar a poluição dos corpos receptores de seus efluentes, a deterioração das tubulações coletoras de esgoto e, danos a eficiência das estações de tratamento de esgoto, também contribui para a geração de um passivo ambiental nas universidades, os quais são acumulados anualmente à espera de tratamento adequado em precárias condições de armazenamento. Dentro deste cenário, o presente estudo visa caracterizar e avaliar o gerenciamento dos resíduos químicos do Laboratório de Engenharia Sanitária (LES) da Universidade do Estado do Rio de Janeiro (UERJ). Quanto aos meios, foram realizadas pesquisas bibliográficas, eletrônicas e documentais, assim como entrevistas com os principais atores do gerenciamento dos resíduos no laboratório foco deste estudo. O estudo revela que o gerenciamento dos resíduos gerados em tal laboratório é realizado de maneira incipiente. As metodologias utilizadas em todas as etapas do gerenciamento, desde a geração dos resíduos até a destinação final dos mesmos carecem de melhorias para também a melhora da qualidade ambiental das atividades de pesquisa e de ensino do laboratório. Além da inexistência de normas internas para a padronização e controle do processo de gerenciamento, o laboratório também carece de estrutura física e financeira para a adequação do processo. A partir do diagnóstico deste cenário, foi possível o reconhecimento de riscos relacionados às características dos reagentes químicos somados as condicionantes ambientais do laboratório, mais especificamente, às condicionantes presentes no local do armazenamento dos resíduos. Tais riscos possuem a natureza de riscos químicos, físicos, toxicidade e riscos de explosão. Ainda na caracterização deste cenário, foi possível o reconhecimento do não cumprimento de legislações pertinentes ao tema. Conclui-se que, de maneira geral, as universidades carecem de investimentos na temática de gestão ambiental nas políticas institucionais e dia-a-dia das universidades. O laboratório em questão também não foge a esta realidade e, por tal razão, também carece de investimentos financeiros, investimentos em treinamento e investimentos na estruturas físicas para todos estes darem suporte a implantação de um gerenciamento de resíduos eficiente e consistente.

Specification of optimum holistic building environmental and energy performance information to support informed decision making

Political drivers such as the Kyoto protocol, the EU Energy Performance of Buildings Directive and the Energy end use and Services Directive have been implemented in response to an identified need for a reduction in human related CO2 emissions. Buildings account for a significant portion of global CO2 emissions, approximately 25-30%, and it is widely acknowledged by industry and research organisations that they operate inefficiently. In parallel, unsatisfactory indoor environmental conditions have proven to negatively impact occupant productivity. Legislative drivers and client education are seen as the key motivating factors for an improvement in the holistic environmental and energy performance of a building. A symbiotic relationship exists between building indoor environmental conditions and building energy consumption. However traditional Building Management Systems and Energy Management Systems treat these separately. Conventional performance analysis compares building energy consumption with a previously recorded value or with the consumption of a similar building and does not recognise the fact that all buildings are unique. Therefore what is required is a new framework which incorporates performance comparison against a theoretical building specific ideal benchmark. Traditionally Energy Managers, who work at the operational level of organisations with respect to building performance, do not have access to ideal performance benchmark information and as a result cannot optimally operate buildings. This thesis systematically defines Holistic Environmental and Energy Management and specifies the Scenario Modelling Technique which in turn uses an ideal performance benchmark. The holistic technique uses quantified expressions of building performance and by doing so enables the profiled Energy Manager to visualise his actions and the downstream consequences of his actions in the context of overall building operation. The Ideal Building Framework facilitates the use of this technique by acting as a Building Life Cycle (BLC) data repository through which ideal building performance benchmarks are systematically structured and stored in parallel with actual performance data. The Ideal Building Framework utilises transformed data in the form of the Ideal Set of Performance Objectives and Metrics which are capable of defining the performance of any building at any stage of the BLC. It is proposed that the union of Scenario Models for an individual building would result in a building specific Combination of Performance Metrics which would in turn be stored in the BLC data repository. The Ideal Data Set underpins the Ideal Set of Performance Objectives and Metrics and is the set of measurements required to monitor the performance of the Ideal Building. A Model View describes the unique building specific data relevant to a particular project stakeholder. The energy management data and information exchange requirements that underlie a Model View implementation are detailed and incorporate traditional and proposed energy management. This thesis also specifies the Model View Methodology which complements the Ideal Building Framework. The developed Model View and Rule Set methodology process utilises stakeholder specific rule sets to define stakeholder pertinent environmental and energy performance data. This generic process further enables each stakeholder to define the resolution of data desired. For example, basic, intermediate or detailed. The Model View methodology is applicable for all project stakeholders, each requiring its own customised rule set. Two rule sets are defined in detail, the Energy Manager rule set and the LEED Accreditor rule set. This particular measurement generation process accompanied by defined View would filter and expedite data access for all stakeholders involved in building performance. Information presentation is critical for effective use of the data provided by the Ideal Building Framework and the Energy Management View definition. The specifications for a customised Information Delivery Tool account for the established profile of Energy Managers and best practice user interface design. Components of the developed tool could also be used by Facility Managers working at the tactical and strategic levels of organisations. Informed decision making is made possible through specified decision assistance processes which incorporate the Scenario Modelling and Benchmarking techniques, the Ideal Building Framework, the Energy Manager Model View, the Information Delivery Tool and the established profile of Energy Managers. The Model View and Rule Set Methodology is effectively demonstrated on an appropriate mixed use existing ‘green’ building, the Environmental Research Institute at University College Cork, using the Energy Management and LEED rule sets. Informed Decision Making is also demonstrated using a prototype scenario for the demonstration building.
