Environmental risk assessment in financial institutions
Have the environmental risk assessment policies and procedures instituted by banks been successful in promoting the welfare of the environment? Have these policies and procedures succeeded in protecting banks from environment related liability? This thesis examines the impact of environmental risk …

Environmental risk assessment and human pharmaceuticals: limitations and future improvements
… reported. All new pharmaceuticals require an environmental risk assessment (ERA) prior to market authorisation. The aims for this research were to (1) assess the limitations of the current ERA by comparing crude and refined predicted environmental concentrations (PECs) used in ERAs with …

Environmental risk assessment of heavy metals in urban street dust
Environment risk assessment of heavy metals has been widely used as a scientific method for evaluating possible environmental hazards presented in a product, a system and/or an industrial process. The results have been used for setting occupational standards and environmental regulations. However, …

Environmental risk assessment of a genetically-engineered microorganism, Erwinia carotovora
Environmental use of genetically-engineered microorganisms (GEMs) has raised concerns over potential ecological impact. Development of microcosm systems useful in preliminary testing for risk assessment will provide useful information for predicting potential structural, functional, and genetic …

Environmental risk assessment for an informal e-waste recycling site in Lagos State, Nigeria
… that the informal E-waste recycling may pose a risk to human health and the environment, this study aims to evaluate the e-waste contamination and the environmental and human health impact of informal e-waste recycling on the exposed population using the risk assessment framework. The …

Feral oilseed rape populations within a scottish landscape : Implications for GM coexistence and environmental risk assessment
… major uncertainties, however, over the long term environmental and economic consequences of its persistence and invasiveness, particularly in relation to GM coexistence and environmental risk assessment. <br/><br/>This thesis presents a demographic study of feral oilseed rape over an 11 year …

Lacustrine Arcellinida (Testate Lobose Amoebae) as Bioindicators of Arsenic Contamination: A new tool for Environmental Risk Assessment
… of Arcellinida assemblages to inter-annual environmental variability. The results of this study confirmed the faunal homogeneity of assemblages in limnologically similar environments and demonstrated the sensitivity of Arcellinida assemblages to environmental changes at inter-annual time …

Understanding the fate of active pharmaceutical compounds in waters receiving poorly or untreated wastewater for the development of a dedicated environmental risk assessment approach
… ingredients (APIs) is of a growing environmental concern. The inherently biological activity of APIs creates a concern of potential ecotoxicological effects even at very low concentrations. Such risk is particularly exacerbated in low and low-middle income countries (LLMICs) where it …

Integration of substance flow analysis, transport and fate of materials in the environment, and environmental risk assessment for provision of information for regional environmental management: cadmium as a case study in Australia
… give sufficiently rapid feedback for effective environmental management. With regard to the complexity and concern related to environment-health chain effects, there is currently no environmental tool or approach that can provide comprehensive information and indicators covering all major …

Hydrocarbon spills in continental waters: a new regulatory approach in light of Mexico´s energy reform
… if Mexico will benefit from the enactment of an environmental quality standard (EQS) for water contaminated with hydrocarbons, in light of Mexico’s energy reform. In addition, the research assesses the institutional challenges faced when trying to enforce such EQS, and the design elements for any …

Light Enhanced Toxic/tumorigenic Potential of Trinitrotoluene (Tnt) and Analogs
… and 4A must be considered to fully evaluate the environmental hazards of these compounds. The 2A and 4A metabolites of TNT were toxic at environmentally relevant concentrations and their production during biological degradation of TNT related waste must be considered. Binary mixtures of TNT, 2A …

Characterising the functional homology of central nervous system drug targets in larval zebrafish (Danio rerio)
… Addressing this gap is critical for improving environmental risk assessment frameworks, which currently rely largely on apical toxicity endpoints and consider pharmacological mode of action to a lesser degree. This thesis investigates whether conservation of CNS drug targets in fish predicts …

Chemical-sensitive genes in zebrafish (Danio rerio) early development - identification and characterisation of differential expression in embryos exposed to the model compound 3,4-dichloroaniline
In the European Union an environmental risk assessment is required for the registration of new chemicals, biocides, pesticides and pharmaceuticals. In order to avoid the release of potential hazardous substances, various ecotoxicity tests are performed, including acute and chronic fish tests. As a …

The development and harmonisation of risk assessment procedures to evaluate the environmental impact of toxic substances
The environmental risk assessment of substances is introduced and the various controls used to protect the environment are outlined. The European notification system and the risk assessments required as part of the system are detailed. Through an examination of the existing European Union System …

Variability and Uncertainty in Risk Estimation for Brownfields Redevelopment
… methods can be used to estimate the human health risk associated with exposure to contaminants at brownfields facilities. The deterministic method has been the standard practice, but the use of probabilistic methods is increasing. Contaminant data for non-carcinogens and carcinogens from 21 …

Health risk effect of indoor air quality index at adaptive reused museum in Malaysia
… there are still limited studies conducted on the risk assessment of the indoor air quality (IAQ) which affect towards the people in the public building, especially in the museum. As one of the environmental risk assessment tool, the environmental quality index was utilised to determine whether the …
