The fast coastal development has caused serious marine pollution with powerless policy and inappropriate management scheme, especially in dealing with the marine debris. The marine debris has been the major coastal problems over the year because of human related activities and nature disasters frequently occurring during the monsoon season or typhoon period each year around the coastal Taiwan. These make the marine debris issues to become the top priority for the government of Taiwan in dealing the marine pollution especially after the 8th of August, 2009. The present study is initiated to assess the current data information, policy, and regulation of Taiwan¡¦s coastal area debris management. This study uses comparative analysis, integrations of internal and external monitoring and management of marine debris-related researches. This thesis reports that Taiwan administration must undertake all three aspects of integration, monitoring and management to effectively managing the marine debris. As the aspect of integration, because marine debris come from land-based emissions, ocean currents carry and sea-based activities, the government needs to consolidate the entire river, rain water drainage systems, ports, ships and fishing areas, to establish an inter-ministerial and responsible agency, to truly develop and implement the bill of marine debris management. As the aspect of monitoring, the central and local government as well as civil society must do their best together to develop the monitoring operations format which needed both considering national unity and local differences, to take long-term continuous monitoring of all major coastal areas, to clarify the source of marine debris, so that government could effectively control the sources of marine debris. As the aspect of management, since the a variety of marine debris sources and diversity of monitoring, the inter-ministerial and responsible agency not only coordinates the various related fields, but also combines the public and private sectors, to truly implement the bill of marine debris management. Overall, Taiwan government must use a variety of economic incentives, cooperation issues and the law, as well as combines the strength of the IV private sectors to effectively manage the management of marine debris.

Polybrominated diphenyl ethers (PBDEs) are anthropogenic chemicals whose environmental behavior is similar to the well-known polychlorinated biphenyls (PCBs). Few studies have quantified the amount and distribution of PBDEs in the southern hemisphere and Antarctica. The analyses reported in this dissertation document the levels of PBDEs in lichens, mosses and seabird eggs collected at King George Island, Antarctic Peninsula. The analyses were carried out using Gas Chromatography/Electron Impact-Mass Spectrometry (GC/EI-MS). Employing the ion stacking technique lowered detection limits and ensured instrument selectivity and sensitivity to the compounds of interest. Lichens and mosses absorb PBDEs directly from the atmosphere and their contamination indicates that long-range transport is the primary source of these chemicals to King George Island. The congener patterns of PBDEs in plants indicate that commercial mixtures of Penta-BDE and Octa-BDE have reached Antarctica. Differences in the levels of PBDEs observed in lichens and mosses are probably due to factors that govern the uptake of PBDEs from the atmosphere. Contamination in lichens showed a positive correlation with local precipitation. Conversely, absorption of PBDEs in mosses appears to be controlled by other plant-specific factors. Marine phytoplankton-derived aerosols are hypothesized to play an important role in the atmospheric transport of PBDEs to the Antarctic environment. PBDEs in south polar skua eggs revealed much higher concentration than in penguin eggs. This is likely associated with the northward migration of these seabirds during the non-breeding season. While penguins reside year-round in Antarctica, south polar skuas migrate northward and can be seen in boreal oceans during the austral winter. Distribution of PBDEs in penguin eggs matches the pattern found in local vegetation suggesting a common source for the chemicals. In contrast, the congener pattern of south polar skuas suggests that birds breeding at King George Island are wintering in the northwestern Pacific Ocean. A potential metabolism of PBDEs in penguin eggs during the incubation period seems to be limited. Most congeners were unaltered from source material in the eggs of chinstrap and gentoo penguins. Low levels of PBDEs, short incubation periods and energy constraints may explain these observations.

The aim of this thesis was to study the effect of the treated oil refinery effluents of Bahrain Petroleum Company ( BAPCO ) on the marine environment. The study has been carried out in seven chapters, the first de~ling with general introduction about the physical environment of the Arabian Gulf and its oil industry in addition to marine pollution and fishery in Bahrain. The second chapter was aimed at studying the quality of water at different areas in Bahrain to compare it with the quality of water at an area adjacent to the refinery outfalls. The third chapter deals with the impact of the refinery on the marine environment. The research approach adopted was ecological and observational I involving water and sediment analysis. The fourth chapter was aimed at studying the effects of the refinery effluents on the fish through toxicity tests and estimation of trace metals and hydrocarbons in the fish tissues. The studies were conducted with several effluents from the main and side streams of the refinery, outlets of the induced air flotation unit and Sitra separator. The fifth chapter was aimed at studying the effect of Sitra oil storage tanks treated effluent on the intertidal fauna of the adjacent area. The sixth chapter deals with a general discussion on the whole studies. While the seventh chapter deals with sions and recommendations. From the study conducted , it could be said that in general the water quality of the western and northern regions of Bahrain is better than the water quality of the eastern region. The east has in general higher pH, higher ammonia, higher nitrite, lower nitrate, and higher phosphate levels than the other regions. The higher concentrations of all these substances reflects the urbanisation and industrialisation of this part of Bahrain and the consequent discharges of waste material. The fish, safee, were tested with different concentrations of the refinery main stream effluent using both short and long term exposures. The same experiment was set up using effluents from the side stream, the I.A.F. discharge of the refinery and Sitra separator outlet. The results indicated a greater toxicity of pollutants in the I.A.F. and Sitar separator effluents than in the main and the side stream effluents. The lethal concentration of I.A.F. and Sitra separator effluents which brought death to fifty percent of the test population of fish (safee) within 96 hours was approximately twenty percent. Fish from the experimental media showed a higner concentration of heavy metals. The study of the effect of Sitra oil storage tanks treated effluent on the intertidal fauna of the adjacent area revealed that no fauna was found at stations located just outside the effluent outlet. The sediment of these stations was black, slimy, heavily oiled with a bad smell and contains dead shells and turrets. Away from the effluent, a diverse fauna was found. It is concluded that the BAPCO refinery has a measurable impact on the marine environment of the east coast of Bahrain, and recommenqations are made tor the development of future policies with regard to Bahraini coastal waters.
