Abstract: In 2001, 122 nations (including Singapore) signed the Stockholm Convention under the United Nation Environmental Program to phase out a suite of 12 persistent organic pollutants (POPs) considered as a potential risk to the environment and human health. In May 2005 Singapore ratified its obligations under the convention, becoming the 100th country to do so. In the present study, detailed field studies were undertaken to determine the distribution and fate of POPs in the ocean and atmosphere of Asiana??s regions, including Singapore, Hong Kong and the Indian Ocean. Contaminants of interest included a??conventionala?? POPs, such as polychlorinated biphenyls (PCBs) and organochlorine pesticides, but also the polybrominated diphenyl ethers (PBDEs) which have emerged in the last decade as potential a??newa?? POPs of concern. The sea-surface microlayer, the uppermost 40-100 micrometer boundary layer between ocean and atmosphere, was studied extensively to determine its role in controlling the fate of POPs in the marine environment.
