Dioxins Contamination in Sediment and their Effect on Accumulation in the Portuguese Oyster (Crassostrea angulata) and White Shrimp (Litopenaeus Vannamei)

This research aims to realize whether the dioxin accumulation in oyster and white shrimp which were cultured pollutant sediment. presented evidence indicated that was detected all experimental groups with high concentration accumulated experiment animals. Observation of concentration, PCDD/F, 2,3,7,8-T4CDD sediment declined time elapsed. Detection animal, accumulative maximum amounts as 3746.16 (pg-TEQ/g d.w.) 705.44 d.w.). The amount supernatant quite low, less release into water. filter habit animal demersal both organs. As our findings, is transferred shrimp, increased by bio-magnification elapsed time.
