Cadmium Contamination in the Sediments of Love River Mouth, Taiwan

Abstract:

Major objectives of this study are to evaluation the enrichment, accumulation, and potential ecological risk of cadmium (Cd) in the sediments of Love River mouth, Taiwan. Ten monitoring stations were installed near the mouth of Love River to collect sediment samples for analyzing Cd. Results of laboratory analyses show that contents of Cd in the sediments are between 0.27 and 1.25 mg/kg with an average of 0.74±0.33 mg/kg. The spatial distribution of Cd reveals that the Cd concentration is relatively high near the boundary of the river mouth, 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 analysis imply that the sediments can be characterized as minor to severe degree of Cd enrichment. Results of geo-accumulation index analysis indicate that the sediments can be characterized as none to moderately strong degree of Cd accumulation. Results of potential ecological risk index indicate that the sediments at Love River mouth has moderate to high ecological potential risk.
