The Assessment of Mangrove Sediment Quality in Mengkabong Lagoon: An Index Analysis Approach
نویسندگان
چکیده
The objectives of this study are to use different types of indexes to assess the current pollution status in Mengkabong lagoon and select the best index to describe the Mengkabong sediment quality. The indexes used in this study were Enrichment Factor (EF), Geo-accumulation Index (Igeo), Pollution Load Index (PLI) and Marine Sediment Pollution Index (MSPI). Different indexes give diverse status of Mengkabong lagoon sediment quality. MSPI has an advantage over the earlier indexes and viewed as a simple summary of the state of the sediment. However, the heavy metal assessment indices are not to be used as the only indicator for sediment quality. Sitespecific, biological testing and ecological analysis of existing benthic community related to sediment contamination are needed for final decision making in the case of Mengkabong lagoon.

Overlying water, sediment, rhizosphere sediment and mangrove seedlings in the Futian mangrove forest were analyzed for heavy metals. The results showed that mangrove plant acidified sediment and increased organic matter contents. Except for chromium (Cr), nickel (Ni) and copper (Cu) in Aegiceras corniculatum sediment, heavy metals in all sediments were higher than in overlying water, rhizospher...
