The aim of this study was to determine the origin of heavy elements and determine the severity of pollution index in Genaveh sun sediments in 2015. For sampling stations were collected for sampling. Sampling was performed with Grub and after transfer to the laboratory, completes decomposition and chemical separation process was performed in 5 steps. The effect of pollution was determined and the effect of the concentration of elements in the phases of man-made and its natural characterization was determined. The results showed that the average concentrations of heavy elements copper, nickel, lead, vanadium, zinc, manganese, iron, calcium and aluminum were 19.50, 42.25, 18.75, 71.25, 14.50, 11.75, respectively. 3.12, 4.37, 3.10 and the average concentration of organic matter are 4.10 mg/l. Ipoll index was used to detect contamination in Genaveh estuary. The results of heavy elements in the study area indicate no pollution in the sediments of Genaveh estuary. Compared to the average elements in the Earth's crust and global sediments, the concentration obtained in this study was lower than the average of the Earth's crust and global sediments. The source of man-made and natural contaminants was the highest percentage in the natural sector. Regarding the origin of heavy elements and determining its dependence on oil and land indices, it can be said that since the element nickel, which is an indicator of oil pollution, and aluminum, which is an indicator of the earth's source, showed a correlation of 0.93 with copper. It is of both terrestrial and petroleum origin. The results of a five-step chemical separation analysis of the elements showed the highest separation in the resistant phase, indicating a strong association of elements with soil components, and a non-regenerative environment that could break this bond under There is no environment, Unless this link is broken by natural disasters. |
