ABSTRACT Ecological risk assessment (ERA) has been adopted worldwide for characterizing and assessing risks to the natural environment imposed by human activities. The idea of ERA has emerged in the United States as early as the 1980s. Since then, sets of official ERA framework and procedures have been developed. It serves as a tool to quantitatively and qualitatively evaluate the ecological impacts to the environment. The ERA procedures are basically divided into three steps: (1) Problem formulations; (2) Characterization of exposure and ecological effects; (3) Risk characterization. By identifying the problems and characterizing the risks of human activities to the species and to the environment, accurate information is brought up to the decision-makers. Thus, suitable development strategies, control regulations and measures can be implemented to avoid or minimize such ecological and environmental risks. This study specifically aimed to review the current ERA processes for protecting marine mammals in Hong Kong and provide some recommendation for further improvement. Although sets of ERA guidelines have been well established in some countries/regions (e.g. the US and Australia), others like Hong Kong do not have their own set of ERA guidelines. Nevertheless, ERA studies for marine mammals have been recently conducted in Hong Kong, by taking reference to the United States Environmental Protection Agency (USEPA) guidelines. In general, the assessment processes include the investigation on the level of contaminants in the physical environment (i.e. water and sediment), the diets and the composition of the internal organs of stranded cetacean individuals. The detailed methodology, procedures, pros and cons of each of the above assessments are critically reviewed and discussed in - 3 -this dissertation. As the ERA guidelines in Hong Kong are taken from overseas countries, they may not totally suit the local condition. Besides, in most of the local ERA studies, general background information, such as the actual health effects of contaminants on the marine mammals, the distribution and the site residency time, are always lacking. Although the Hong Kong SAR Government has conducted a routine monitoring programme to quantify the level of common contaminants in marine sediments and biota, corresponding actions such as proper ERA processes have not been fully taken in accordance with the findings of the survey. In this connection, recommendations for development of a local ERA are given, while the possibilities of ERA serving as an efficient and scientific tool to assess ecological issues, and to be promoted and fully implemented in Hong Kong are discussed. - 4 - DOI: 10.5353/th_b3984913 Subjects: Ecological risk assessment - China - Hong Kong Cetacea - China - Hong Kong

Book Description
The World Ocean Assessment - or, to give its full title, The First Global Integrated Marine Assessment - is the outcome of the first cycle of the United Nations' Regular Process for Global Reporting and Assessment of the State of the Marine Environment, including Socioeconomic Aspects. The Assessment provides vital, scientifically-grounded bases for the consideration of ocean issues, including climate change, by governments, intergovernmental agencies, non-governmental agencies and all other stakeholders and policymakers involved in ocean affairs. Together with future assessments and related initiatives, it will support the implementation of the recently adopted 2030 Agenda for Sustainable Development, particularly its ocean-related goals. Moreover, it will also form an important reference text for marine science courses.

Book Description
Risk assessment is the cornerstone of contemporary environmental protection. You must find the answers to questions such as: what might be the impacts of the new synthetic chemicals, what problems might arise from the normal operations of industry, what are the chances of accidental releases and how will they impact the environment? Understanding and assessing these risks is essential to sound environmental policy and management. The first book to address the application of the current National Research Council (NRC) risk assessment paradigm to the coastal marine environment, Coastal and Estuarine Risk Assessment covers topics that range from pollutants of emerging concern to bioavailability and bioaccumulation at the suborganismal through landscape levels. It explores the necessary applications for modifying the NRC paradigm and presents a series of steps to actually accomplish an effective assessment using the modified paradigm. The book highlights the logical framework for assessing causation, and measurement of toxicant fate and effect. The chapter authors bring together experiences from academia, private consultants, and government agencies, resulting in a rich mixture of experience and insights. Exploring the science of exposure, effect, and risk in coastal and estuarine environments, Coastal and Estuarine Risk Assessment gives you a building block approach to the fundamental components of risk assessment.
