INVESTIGATION OF Pb AND Ni LEVELS IN SUNFLOWER PLANT AGRICULTURE TWO DIFFERENT PH ENVIRONMENTS

Abstract

In this study, in the soil samples collected from farmland with two different pH environments located in Kırklareli Province, heavy metals (Pb and Ni) were aimed to investigate the relationship. The working pH values are took in 3 different periods (after the formation of the plant, week of 1 and 6, harvest time) from the farm land in the town of Kırklareli and Kavaklı. In order to determine the concentration of Pb and Ni metals, the reading process was performed by the Flame Atomic Absorption Spectrophotometer (FAAS). The concentrations of Pb and Ni metals in soils in the first region were 36.3-43.7 mg/kg and 12.6-14.9 mg/kg, in the second region soil concentrations were 11.7-17.1 mg/kg, 0.09-0.24 mg/kg, 3.12-4.353 mg/kg, 7.89-11.2 mg/kg, 56.3-9.54 mg/kg, respectively. The concentrations of Pb and Ni metals in first region plant components were 1.93-12.1 mg/kg, and 0.56-11.8 mg/kg, the second region was 6.92-14.8 mg/kg and 0.58-9.37 mg/kg, respectively. The relative standard deviation (RSD) was found to be less than 10%. The RSD of analysis of samples have satisfying precision.
