Concentrations of 2,3,7,8-substituted polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) were determined in 14 sediment samples collected from four sites in the Mai Po Marshes Nature Reserve (within a RAMSAR Site) and from another six sites in Victoria Harbour and along the Hong Kong coastline. Elevated levels of PCDDs, and particularly OCDD, were detectable in all samples collected from the Mai Po Marshes and five of the six sites. In contrast to PCDDs, PCDFs were mainly found in sediment samples collected from industrial areas (Kwun Tong and To Kwa Wan) in Victoria Harbour. PCDD/F levels and congener profiles in the samples from the Mai Po Marshes Nature Reserve in particular show strong similarities to those reported in studies which have attributed similar elevated PCDD concentrations to nonanthropogenic PCDD sources. 相似文献

The renaissance in geographical 'bloc' development in the 1990s has generated expectations that prevailing international regionalism is compatible with the dominant global integration model. Nascent regionalism in the Asia Pacific best captures this trend with regional initiatives being established on the basis of 'open' regionalism as opposed to 'closed' regionalism that is associated potentially with institution building and regional governance. In this paper, I examine the shape and nature of Asia Pacific regionalism. I show how countries here favour a process of regime building that is centred on network building among state and private actors without any goal towards institution building. Asia Pacific regionalism is less concerned with the production and governance of regional space than the assertion of a collective Asian political culture that preserves state sovereignty. 相似文献
