Abstract

Water pollution occurs due to the inclusion of chemical substances, components in the form of gases, and solvents so that the quality of water becomes polluted and harmful to the life of organisms in the waters, especially in fish farming. Polluted waters can contain heavy metals. fish can be exposed to heavy metals due to polluted waters. Heavy metals with high or low levels can also cause various types of dead water biota. If the fish exposed to heavy metals consumed by humans will over-accumulate or accumulate in the body, thus endangering health. This study was conducted to determine the levels of heavy metals Lead (Pb) and Zinc (Zn) contained in the meat of fish bandeng in the market Kalanganyar Sidoarjo with Atomic Absorption Spectrophotometer (AAS). This research was conducted in Applied Chemistry Laboratory of Medical Laboratory of Faculty of Health Sciences, University of Muhammadiyah Sidoarjo and Chemistry Laboratory of FMIPA Universitas Islam Maulana Malik Ibrahim Malang in February-April 2021. In this study using descriptive cross sectional research type. Data analysis method using measurement and observation as well as descriptive statistical analysis. 20 samples were used. The results of heavy metal levels in this study obtained the highest levels of lead heavy metal (Pb) of 0.354 mg/kg. While the lowest level is 0.062 mg/kg. Zinc (Zn) heavy metal content is highest at 3,132 mg/kg. While the lowest level is 0.606 mg/kg.

Abstract

Sidoarjo City in East Java Province has a pond area of up to 7.68%. One of the cultivations developed in ponds is tiger shrimp (Penaeus monodon), which are mostly sold in Sidoarjo. The presence of metals in aquatic bodies comes from natural sources that enter can be the erosion of mineral rocks found in the aquatic environment. Tiger shrimp is one type of shrimp that is preferred by most Indonesian people. If this shrimp is contaminated by heavy metals, it will harm the people who consume it. This research was conducted to find out the levels of heavy metals Timbal (Pb) and Seng (Zn) contained in tiger shrimp (Penaeus monodon) windu shrimp in the market of Sidoarjo with the Atomic Absorption Spectrophotometer (AAS) method. This research was conducted at the Laboratory of Applied Chemical Technology Medical Laboratory of the Faculty of Health Sciences, University of Muhammadiyah Sidoarjo and the Chemistry Laboratory of FMIPA of Maulana Malik Ibrahim University of Malang. Data analysis methods use measurement and observation as well as descriptive statistical analysis. The results of heavy metal levels in this study obtained the highest levels of lead heavy metals (Pb) of 0.596 mg/kg while the lowest levels amounted to 0.544 mg/kg and the highest levels of zinc heavy metals (Zn) amounted to 3.930 mg/kg while the lowest levels amounted to 3.016 mg/kg.
