Abstract

Accumulation of heavy metal content in this nature is caused by unstable environmental condition, likes high rates of pollution and wrong waste management systems. Environmental pollution that has the potential to lead to high levels of lead in shrimp paste and fish in Palang, Tuban District, comes from an oil spill from one of the petrochemicals at sea, domestic waste disposal, and air pollution due to motorized vehicles. The aims of this research are to analyze the content of lead (Pb) in shrimp paste and salted fish in Palang, Tuban District. Sample used 4 shrimp paste, 4 salted fish, and 1 sample of sea water were took from household producers. Sampling of shrimp and salted fish shrimp paste used purposive sampling technique. Then, the sample is tested using AAS (Atomic Absorption Spectrophotometer). The results obtained from the lead testing in the sample will be compared with the National Standardization Agency for 2009 concerning the standard threshold for lead on shrimp which is 2.0 mg / kg and the shrimp paste is 1.0 mg / kg. The results showed that 4 samples of shrimp paste and 3 samples of salted fish positive containing lead above the threshold. The highest mean of lead levels in shrimp paste were 8.84 ± 0.12 mg/ kg (T1 code), while the highest leads value in salted fish were 6.72 ± 0.11 mg / kg. According to the test of the entire sample only one sample of salted fish with lead content below the threshold, that was 1.74 ± 0.11 mg/kg. This results positively correlated with the high content of lead in seawater by 0.18 ± 0.13 mg/L. Based on this, it can be concluded that the waters in Palang, Tuban District are polluted.
