Abstract |
|
|
| Water is an essential component of life, fresh water constitutes about 3% of the total water on the earth, only 0.01% of this fresh water is available, with two thirds of the earth covered by water and the human body consisting of 75% of it, it is obvious that, water is one of the prime elements responsible for life. Present study aimed at assessing the heavy metals concentration in water sources across Ushata and Rafin Tsamiya using Micro Plasma Atomic Emission Spectroscopy (MP-AES). The result revealed that, heavy metals for Ushata and Rafin Tsamiya in mg/L (Zn (0.2 and 0.09), Cd (0.00 and 0.00), Fe (0.06 and 0.05), Cu (0.01 and 0.02), Pd (0.02 and 0.08), Ni (0.001 and 0.004) and Mn (0.038 and 0.058)) respectively were present in the water. It can be concluded that the mean concentration is insignificant and the water in those areas is considered a good water, though, on accumulation, heavy metals may have much impact radiation burden of the populace, hence, gross alpha and beta in the area is recommended.
for 226Ra and 162. 302 to 416.111 Bq/kg for 40K with the average values of 17.531, 8.888, 63.265 and 342.289 Bq/kg,
respectively. While at the deep studied sample (Eb), they are ranged from 10.888 to 20.714 Bq/kg for 238U; 4.427 to 16.347
Bq/kg for 232Th; 47.163 to 68.373 Bq/kg for 226Ra and 252.568 to 402.706 Bq/kg for 40K with the average values of 15.415,
10.034, 58.174 and 345.636 Bq/kg, respectively. The radium equivalent activity (Raeq), external hazard indices (Hex) have
average values of 161.93 Bq/kg, and 0.437, respectively. The average values of indoor and outdoor absorbed dose rate in
air were found 70.58 nGy.h-1 and 0.086 nGy.h-1, respectively. The reordered important minerals in the studied area are;
feldspar, quartz, Ilmenite, Rutile, Magnetite, zircon, monazite, Uranothorite, and Apatite. In the present work, 40K was the
significant radionuclide detected in Sharm El loul beach. The concentrations of radionuclides in the studied samples of
Sharm El loul beach during the present investigations were normal and do not produce any harmful health effects to the
local residents. |
