Abstract
Abstract Four marine cores to depth of 2.8 m, from the Urmston Road‐Brothers Channel, Hong Kong, have been analyzed for the trace metals Cu, Zn, Cr, Ni, Mn and Pb, as well as total organic carbon and organochlorines. Most of these elements indicate enhanced concentrations due to anthropogenic inputs in the upper part of the sediment column, with an overall decrease with depth. The concentrations of these elements are lower than in surface sediment from offshore areas near the industrial and urban heart of Hong Kong. Mn and Zn appear to be distributed most evenly through the cores. However, the concentrations of the metals and total organic carbon content in sea bed samples are commonly lower than the adjacent underlying samples. This may be due to deposition of unpolluted sediment disturbed by dredging, diagenetic effects or through the sampling process. Although rank order of metal abundance is similar across cores, correlations between the metals are weak; the exceptions are chromium and copper. Concent...
