Macrobenthic Community in Tolo Harbour, Hong Kong and its Relations with Heavy Metals

Abstract

The present study investigated the macrobenthic community in Tolo Harbour, Hong Kong, aiming at linking heavy metal concentrations to differences in macrobenthic community. The stations investigated in Tolo Harbour have widely contrasting features, with some areas located in the Plove Cove displaying both high species richness and abundance while other areas displaying quite impoverished or even void of macrobenthos. High diversity and abundance of macrobenthos in areas with low heavy metal concentrations were recorded. Strong negative correlation between macrobenthic diversity and heavy metal concentrations was found, and this implicated the pollution-induced degradation of macrobenthos in some locations in Tolo Harbour. These results support the Pearson-Rosenberg model for succession along a pollution gradient. © 2010 Coastal and Estuarine Research Federation.published_or_final_versionSpringer Open Choice, 01 Dec 201
