Abstract
Coastal regions are naturally prone to environmental contamination, including the presence of lead pollutants. Therefore, this research aimed to determine the condition of Pb content in the Mandallle Coast of Pangkep Regency concerning water (temperature, salinity, dissolved oxygen, and pH) and substrate quality (pH, organic matter, and texture). The method adopted was explanatory analysis, directed towards obtaining comprehensive insights into the presence of Pb metal within the waters, water quality parameters, and substrate characteristics of Mandalle Beach along the coast of Pangkep Regency. The research was performed over a duration of three months, spanning from April to June at the precise locale of Mandalle Beach situated in the Mandalle District of Pangkep Regency, Indonesia. The selection of Mandalle Beach stemmed from allegations of lead pollution plaguing the environment and the frequent community activities transpiring in the area amplify the potential for Pb contamination. The results showed that the content of heavy metals was in the non-hazardous range based on the analysis of Pb using an Atomic Absorption Spectrophotometer because the research locations had a lead content below 1 ppm. The constituents of water quality, including temperature, salinity, pH, and oxygen levels are within ranges conducive to the sustenance of aquatic organisms. The analysis of substrate attributes, including pH, organic composition, and texture, indicates that these parameters remain well-suited for the habitation of various organisms.
