Evaluation of Cadmium Contamination in the Surface Sediments of Anping Harbor, Taiwan

Abstract:

This study was conducted using the data collected at the Anping Harbor, Taiwan to investigate and analyze cadmium (Cd) contained in the sediments, and to evaluate the accumulation of Cr and the degree of its potential risk. The results show that samples collected at ten monitoring points contain 0.040.60 mg/kg of Cd with an average of 0.26±0.18 mg/kg. The spatial distribution of Cd reveals that the Cd concentration is relatively high in river mouth region, and gradually diminishes toward the harbor region. This indicates that upstream industrial and municipal wastewater discharges along the river bank are major sources of pollution. Results from the enrichment factor and geo-accumulation index analyses imply that the Bamboo River mouth sediments can be characterized as moderately severe enrichment and moderate accumulation of Cd, respectively. Results of potential ecological risk index indicate that the surface sediment has higher ecological potential risk in Bamboo River mouth. The results can provide valuable information to developing future strategies for the management of river mouth and harbor.
