Abstract

It has been reported that Pearl River Delta (PRD) was significantly contaminated by various toxic chemicals such as persistent organic pollutants (POPs) and personal care products. Recently, several groups of new POPs such as polybrominated diphenyl ethers (PBDEs) and perfluoroalkyl substances (PFASs) have been identified in various abiotic environmental matrices and even detected in the wildlife. It is noteworthy that levels of these persistent toxic pollutants were significantly elevating in the blubber samples of marine mammals over the past decade. In addition to these new POPs, other emerging contaminants, which were regarded as the potential replacements for the banned chemicals, have also been determined in the local environmental samples such as sediment and seawater. In view of the rich marine biodiversity in Hong Kong waters, it is important to elucidate the occurrence of these emerging contaminants in the coastal environment of southern China, especially the vulnerable species such as marine mammals and coral communities. The present study will therefore examine and discuss the occurrence and spatial variations of several emerging contaminants including halogenated flame retardants, perfluoroalkyl substances and organic UV filters in different environmental matrices.
