Abstract

Heavy metal pollution is increasing in line with increasing industrialization. Research on the Heavy Metal Residues in fish from polluted water and unpolluted water in Central Java using descriptive-explorative research approach, using samples of fish from ponds and estuaries . Samples were taken from three locations coastal areas in district of Semarang, Tegal and Pati.  Analysis of heavy metals consists of Pb, Cu, Zn, Hg, Cd, and As by AAS (Atomic Absorption Spectroscopy). The results showed levels of heavy metals from 0.08 to 0.12 ppm Hg above the threshold regulation Ditjen POM RI no 03725/B/SK/VII/89 on fish from polluted and unpolluted ponds and estuaries polluted and not polluted in Pati and Semarang.  Zinc (Zn) heavy metal at 40.11 ppm from unpolluted estuaries district of Tegal above the set threshold. Key words: fish, ponds, esturia, contaminated heavy metals

Abstract

Food safety precautions sufficient attention in considering the many cases of food contamination, one of which is heavy metal contamination of beef shepherd in final disposal facility). Pollution cows  by heavy metals can cause health hazards to humans. The research aims to determine the content of heavy metals (Hg, Cd, Co, Zn, Pb and As). Design research is a survey study with comparisons of meat from cows raised form final disposal and outside. Heavy metal residues form final disposal that exceed the quality standard : a) Zinc 69.50 ppm (Semarang), 47.60 ppm (Surakarta) 46.41 ppm (Sragen). b) Cadmium 0.06 ppm (Surakarta), TPA 0.06 ppm (Semarang).  Heavy metal residues form outside discovered the existence of heavy metals in excess of the quality standard: a) Zinc 52.0 ppm (Sragen), 51.4 ppm (Surakarta), and 47.63 ppm (Semarang). b) Cadmium from Semarang 0.13 ppm. Heavy metals content Pb, Cu, Hg, Co, and As were below the quality standard. The presence of heavy metals content in cows that exceeds a warning threshold of awareness of the need to improve security. Key words: heavy metals, cows, final disposal facility
