This study aims to evaluate heavy metal and selenium contamination in Karataş Lake sediments and assess ecological risks.
Conducted a seasonal study from October 2019 to July 2020.
Collected sediment samples from four stations in Karataş Lake.
Measured metal concentrations using inductively coupled plasma optical emission spectrometer.
Assessed pollution levels with various indices including enrichment factor and geoaccumulation index.
Identified high concentrations of metals in sediments with the order: Fe > Mn > Ni > Zn > Cr > Cu > Pb > Se > Mo > Cd.
Notable ecological risks were linked to Nickel (Ni) and Selenium (Se).
Nickel concentrations exceeded multiple threshold levels, indicating significant pollution.
