Determination of Heavy Metals (Pb, Zn, Cd, Cu) in Coastal Sediments and Fish Urban Area of Semarang, Indonesia

Abstract

This research aimed to determine the concentrations of heavy metals (Cu, Zn, Pb, Cd) pollutants in coastal sediment, Semarang, to create a statistical model based on the result of test that would be obtained from costal sediments samples, to make permite statements about pollution and change that occurs on the state of the environment in the urban catchment, creating database on pollution control in the region and in the future to maintain biodiversity (to give the industrial activities-pollution permits-by official bodies for the protection of the environment in the state). This research would be conducted in 2017 with the location of sampling and water quality measurement conducted at Usman Janatin Street, Semarang. The sample analysis would be conducted at the Diponegoro University Integrated Laboratory. In this research was focused on deep and width. According to some previous studies such as study done by Mancuso et al. that stated the TAL metals analysis results gave a wide scope of the concentration of metals in coastal urban area. Based on the analysis and result, the conclusion as follows: There was relationship between levels of heavy metals and external environment. The relationship was positive, it means the higher levels of heavy metals, the external environment would be more polluted. The lower levels of heavy metals, the external environment would be low polluted. The internal levels of coastal sediment could be used as an index to infer the state of the environment. This heavy metals determination tool could be used to support policy and decision-making.
