Hubungan Kadar Cr dalam Air Tambak terhadap Cr Pada Ikan Nila (Oreochromis niloticus), Ikan Bandeng (Chanos chanos) dan Udang Vaname (Litopenaeus vannamei) di Kawasan Jabon Sidoarjo Relationship of Cr Levels in Pond Water to Cr in Tilapia (Oreochromis niloticus), Milkfish (Chanos chanos) and Vaname Shrimp (Litopenaeus vannamei) in Jabon Sidoarjo Area

Abstract

Disposal of Lapindo mud into Porong river had caused environmental polluted  which might affect water quality and surrounding especially ponds in Jabon Subdistrict, Sidoarjo city. One of hazardous contaminant that harmful to health was chromium (Cr) metal which had carcinogenic effect. The aim of this study was analyzed Cr levels in  ponds water, Nile tilapia (Oreochromis niloticus) flesh, Milkfish (Chanos chanos) flesh, Vaname shrimp  (Litopenaeus vannamei) flesh, and analyzed the correlation of Cr levels ponds water to Cr levels of Nile tilapia, milkfish, Vaname shrimp. Results of study shown that Cr levels of all ponds water sample were <0,0201mg/L which indicated safe to consumed because they were lower than standard of water Cr levels about <0,05 mg/L. Result of Cr levels in Nile tilapia flesh and Milkfish flesh had same Cr levels about <0,0004 mg/kg which indicated safe to consumed because they were lower than standard of Cr levels  fish flesh about <2,5 mg/kg. Shrimp flesh taken from T3 (0,532 mg/kg ) and T5 (0,461 mg/kg) were higher than standard of Cr levels shrimp flesh about 0,4 mg/kg hence need beware to consume. Correlation analyzed of  ponds water Cr levels to  Nile tilapia flesh, Milkfish flesh, Vaname shrimp  flesh Cr levels shown those were not correlation between both of them because P >0,05.
