چکیده
Heavy metal pollution in coastal areas is a serious environmental issue driven by intensive anthropogenic activities. This study aims to assess the potential heavy metal contamination in coastal sediments of Kendari Bay, Southeast Sulawesi, Indonesia, using magnetic susceptibility and X-ray fluorescence (XRF) approaches. A total of 20 sediment samples were collected from three different zones based on anthropogenic activities: port, roadside, and residential areas. Magnetic susceptibility (χlf) was measured using a Bartington MS2 meter with an MS2D sensor, while concentrations of heavy metals (Fe, Co, Cu, Zn) were analyzed using XRF. The χlf values ranged from 4 × 10⁻⁵ to 1265 × 10⁻⁵ SI, with the highest values observed in the port zone. Iron (Fe) concentrations ranged from 25020 to 57490 mg/kg, cobalt (Co) from 150 to 280 mg/kg, copper (Cu) from 10 to 20 mg/kg, and zinc (Zn) from 40 to 800 mg/kg. A weak positive correlation was found between χlf and Fe (r ≈ 0.21), while weak to moderate negative correlations were observed with Co, Cu, and Zn (r ranging from –0.15 to –0.38). These findings indicate that some heavy metals are deposited alongside magnetic minerals derived from industrial and transportation activities. Magnetic susceptibility is proven to be a rapid, non-destructive, and cost-effective method, making it highly suitable as a preliminary screening tool for monitoring sediment pollution in coastal environments.
