Produced water is the largest by-product of oil and gas production. At off-shore installations, the produced water is typically reinjected or discharged into the sea. The water contains a complex mixture of dispersed and dissolved oil, solids and inorganic ions. A better understanding of its composition is fundamental to 1) improve environmental impact assessment tools and 2) develop more efficient water treatment technologies. The objective of the study was to screen produced water sampled from a producing field in the Danish region of the North Sea to identify any containing organic compounds. The samples were taken at a test separator and represent an unfiltered picture of the composition before cleaning procedures. The analytes were isolated by liquid-liquid extraction and derivatized using a silylation reagent to increase the volatility of oxygenated compounds. The final extracts were analyzed by comprehensive multi-dimensional gas chromatography coupled to a high-resolution mass spectrometer. A non-target processing workflow was implemented to extract features and quantify the confidence of library matches by correlation to retention indices and the presence of molecular ions. Approximately 120 unique compounds were identified across nine samples. Of those, 15 were present in all samples. The main types of compounds are aliphatic and aromatic carboxylic acids with a small fraction of hydrocarbons. The findings have implications for developing improved environmental impact assessment tools and water remediation technologies.

Environmental impact assessment (eia) and strategic environmental assessment (sea) are procedures for the prior assessment of impacts of proposed developments before decisions are taken. Customary law and most international agreements relevant for the Arctic Ocean are unspecific about assessment tools and content. The Espoo Convention and its sea Protocol are the only specialised instruments available. They do not cover marine activities well, and not all the Arctic Ocean coastal states are parties. Other problems in the assessment regime are related to uneven geographical and sectoral coverage. Weaknesses may be addressed both globally in the negotiations on a new instrument under the Law of the Sea Convention (losc) on biodiversity beyond national jurisdiction, and in a regional process under the Arctic Council. Important improvements would be the creation of a more specific default mechanism for prior assessment of marine activities and closer linkage of assessments with substantive goals.

Energy consumption by and emissions from buildings contribute greatly to environmental degradation. Currently, an important tool in the study of architectural conservation design is LCA (life-cycle assessment), with the goal of minimizing energy consumption and environmental impact. The research suggests a method to apply LCA analysis and BIM technology to design 3D BIM models and define the relationship between BIM elements and architectural materials. The obvious advantages of combining BIM with LCA have resulted in its wide use for building life cycle assessment. The study propose here quantitative analysis of environmental impact by construction and build an index database for environmental impact assessment of building projects based on analytical hierarchy process. The design plan of the Teaching and Research Building of a University in Nanjing China is taken as the example to calculate energy consumption in response models formed from construction data. From these modeled calculations, then the key environmental impact factors were analyzed. The objective is to suggest an integrated solution to BIM-based environmental impact assessment of building construction and also provide a theoretical support for optimized building design. This case study demonstrates the utility of BIM when performing LCA, providing most of the information needed to perform LCA.

Research and development in hydroinfomatics can play an important role in environmental impact assessment by integrating physically-based models, data-driven models and other Information and Communication Tools (ICT). An illustration is given in this paper describing the developments around the Soil and Water Assessment Tool (SWAT) to support the implementation of the EU Water Framework Directive. SWAT operates on the river basin scale and includes processes for the assessment of complex diffuse pollution; it is open-source software, which allows for site-specific modifications to the source and easy linkage to other hydroinformatics tools. A crucial step in the world-wide applicability of SWAT was the integration of the model into a GIS environment, allowing for a quick model set-up using digital information on terrain elevation, land use and management, soil properties and weather conditions. Model analysis tools can be integrated with SWAT to assist in the tedious tasks of model calibration, parameter optimisation, sensitivity and uncertainty analysis and allows better understanding of the model before addressing scientific and societal questions. Finally, further linkage of SWAT to ecological assessment tools, Land Use prediction tools and tools for Optimal Experimental Design shows that SWAT can play an important role in multi-disciplinary eco-environmental impact assessment studies.
