ASSESSMENT OF CADMIUM (Cd) CONTAMINATION IN MUD CRAB (Scylla spp.) AND SEDIMENT FROM SEGARA ANAKAN LAGOON, CILACAP, INDONESIA
ABSTRACT: The study aimes to
examine the accumulation level of selected heavy metal Cd in various of common mud
crab (Scylla spp.) samples from Segara Anakan Lagoon-Cilacap. Mangrove crab and
sediment samples were taken from Segara Anakan (108046’–109005’E; 7034’–7048’S)
and were analyzed using Atomic Absorption Spectrophotometer (AAS). The Cd
extent in Scylla spp. varied from 0.084 - 0.273 ppm which still below the
European Commission (2006) threshold value (0.5 ppm). On the other hand Cd concentration
in sediment for most stations value (0.625 - 1.635 ppm) have exceeded the
Interim marinesediment quality guidelines (ISQGs value; 0.7 ppm) except for
station 2 and 4. Concerning the sediment, to interpret and assess the
contamination status four indices were used, namely Contamination Factor (CF),
Enrichment Factor (EF), Pollution Load Index (PLI), and Geoaccumulation Index
(Igeo). The results show the Segara Anakan sediment value for CF varied 3.125 -
8.175, EF was 50.481, PLI was 5.381 and Igeo varied 0.319 - 0.736. The finding
result shows the Segara Anakan sediment could be considered as moderately
polluted.
