%X The distribution, enrichment, and accumulation of zinc
(Zn) in the sediments of Kaohsiung Ocean Disposal Site (KODS),
Taiwan were investigated. Sediment samples from two outer disposal
site stations and nine disposed stations in the KODS were collected per
quarterly in 2009 and characterized for Zn, aluminum, organic matter,
and grain size. Results showed that the mean Zn concentrations varied
from 48 mg/kg to 456 mg/kg. Results from the enrichment factor (EF)
and geo-accumulation index (Igeo) analyses imply that the sediments
collected from the KODS can be characterized between moderate and
moderately severe degree enrichment and between none and none to
medium accumulation of Zn, respectively. However, results of
potential ecological risk index indicate that the sediment has low
ecological potential risk. The EF, Igeo, and Zn concentrations at the
disposed stations were slightly higher than those at outer disposal site.
This indicated that the disposed area centers may be subjected to the
disposal impaction of harbor dredged sediments.
