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.
