Abstract: | Heavy metal contamination in sediments of the Karasu spring was investigated in the presented study. In this respect, sediment
samples were collected from contaminant sites along the spring starting from the spring water manifestation site, base of
the Akkaya dam to the dam exit site. Heavy metal concentrations were determined by X-ray Fluorescence Spectrometer. Cobalt,
copper, arsenic, tin, nickel, zinc, cadmium, lead, aluminum, iron, titan, chromium and manganese contents of the Karasu creek
sediments are found as 18.30–69.00, 12.40–595.0 5.50–345.3, 5.80–15.1, 10.9–64.1, 28.90–103,300, 4.1–356.2, 7.70–37,840, 13,460–109,400,
11,740–62,900, 22.18–59.04, 41.70–369 and 12.09–3,480 mg/kg, respectively. Results indicate the presence of a contamination
in the Karasu creek. All the metal concentrations were found to be exceeding their acceptable limit values. Eutrophication
is developed in the Karasu creek and the Akkaya dam. It is thought that heavy metal accumulation in the creek is originated
from discharge from mine quarries, industrial and domestic wastes. Protection zones should be defined and all necessary measures
must be taken along the Karasu creek. |
