【 摘 要 】

Kenjeran waters are one of the waters located in the eastern part of the city Surabaya which has been polluted by heavy metals. The presence of heavy metals in the waters, automatically affect bivalves that live in these waters which will accumulate the metal on the body. This research aim was to determine the Health Benefit Value of Selenium (HBV-Se) as a food safety index from mercury contamination in bivalves consumption and to recognize MeanWeekly Intake (MWI) bivalves consumption in Kenjeran waters. The concentration analysis for Selenium using ICP-OES and Total mercury (THg) using Mercury Analyzer NIC-MA3000. Mercury and Seleniumwere calculated to gain HBV-Se index. The mercury concentration result showedPerna viridis 0.09 mg/kg, Siliqua patula 0.07 mg/kg, Trisidos tortuosa 0.08 mg/kg, and Anadara antiquata 0.08 mg/kg. The selenium concentration in bivalves between 0.91 mg/kg-2.49 mg/kg. The concentration of mercury below the quality standard on the limit determined by SNI, about 1 mg/kg. Total mercury from highest concentration were Perna viridis>Anadara antiquata>Siliqua patula>Trisidos tortuosa. From the calculation HBV-Se result showed positive value, it means indicating mercury contained in bivalves at Kenjeran Waters were not potentially to be toxic on the body. For the safety purpose, maximum consumption on bivalves for an adult is Perna viridis 8.64 kg/week, Siliqua patula6.62 kg/week, Trisidos tortuosa 3.91 kg/week and Anadara antiquata 4.49 kg/week. For the same reason, the maximum consumption for children Perna viridis 1.44 kg/week, Siliqua patula 1.10 kg/week, Anadara antiquata 0.65 kg/week, Trisidos tortuosa 0.75 kg/week.
