Investigation of Toxic Metal Contamination in Water and Sediments of Gölbaşı Lake (Adıyaman)
Öz
Gölbaşı
Lake, which forms the most important wetland between the Mediterranean Region
and the Southeastern Anatolia Region, is a natural lake and protected as a
natural park. Excessive grazing causes damage to the vegetation around the
villages and makes the area vulnerable to erosion. Increased agricultural
production in the region has also brought pollution problems. Measures must be
taken for the sustainability of water and sediment quality of this lake which
is from our natural wetlands. For this purpose, in this study, water quality of
Gölbaşı Lake and heavy metal rezidues in water and sediment were evaluated. Water and sediment
sampling were carried out in two periods, dry (August 2017) and wet (November
2017). Ammonia, nitrite, nitrate, phosphate and biological oxygen requirement
values of water quality parameters were examined. Residue quantities of heavy
metals such as Pb, Cu, Zn, As, Cr and Cd have been evaluated in lake water. In
the lake sediment, 12 types of metal (Pb, Cu, Zn, As, Cr, Cd, Ni, Se, Co, Fe,
Al and Mn) were analyzed. Gölbaşı Lake was found to be in the first class
according to the classifications of the water quality, physicochemical
parameters and elements of Continental Water Surface Water Resources. In
general, sediment metal remains are in the order of Fe˃Al˃Mn˃Ni˃Cr˃Zn˃Cu˃Pb˃Co˃As˃Se˃Cd. The metal concentrations
in the sediment of the lake are below the limit of sediment quality guidelines
determined by USEPA. Nevertheless,
in order to ensure the sustainability of the water and sediment quality of
Gölbaşı Lake, which is one of our natural wetlands, it is necessary to remove
the pollutants that may be a source around the lake or to take precautions
about it.
