Chemical Characteristics and Correlation of Heavy Metal Elements in Lumpue Beach, Parepare City

Abstract

This study aims to analyze heavy metal elements in Lumpue Beach. Characterization of Lumpue Beach sediments in addition to the megaskopis and petrographic observation approach, determination of mineral chemical aspects using ICP-OES analysis was also done. This analysis done on 7 samples of very fine sand obtained from sieving and aimed to determine the level of heavy metal elements on the ppm scale. Based on ternary plotting diagrams, that the dominant Lumpue Beach is composed of sedimentary texture very fine sand - coarse sand. The ratio of Pb elements in the study area has an average level of 41.38 ppm and a trend line R2 = 0.25, Cd has an average level of 1.65 ppm and a trend line R2 = 0.12, Cu elements has an average level of 14.5 ppm and a trend line R2 = 0.02imes and Zn element has an average level of 62.125 ppm and a trend line R2 = 0.0022. They are indicated to exceed normal limits. Based on the use of Pearson method with two paired variables on metals Cu, Fe, Ni, Zn, Pb, Ti and Mn, it is known that Cu metal has a very weak correlation with Fe, Zn, Ni, Pb and Ti, while Fe metal has a strong correlation to Zn., Ti and Mn but have a weak correlation with Ni and Pb. Fe and Al metals are deposited with low values, this occurs in the concentrations of the two metals and follows the sediment fraction controlled by currents and tides.
