An Environmental Study of Some Water Characteristics of Al-Anaba Desert Lake in Southern Libya
This study aimed to estimate the physical and chemical properties of Al-Anaba desert lake. The study found that the average temperature ranged between 8.15 and 15.3. The pH rates of the water surface of Annaba were close to the general average of 9.54. The dissolved oxygen ranged from 3.97 to 6.54 mg/l in both the west and south of the lake, respectively. There were no differences in the concentrations of total dissolved salts (TDS) with a general average of 49072 mg/l. The study showed differences in the sodium element concentration from 6.51 mg/l to 8.61 mg/l. There were clear differences in the concentration of the potassium element in the different directions of the lake water with a general average of 0.716 mg/l, which is higher than the concentration of the element in clean sea water (0.38) mg /l. The study showed clear differences in the concentrations of phosphate ions with a general average of 5.28 mg /l. Additionally, the lake is home to various animals such as birds, sea geese, insects like mosquitoes, and aquatic organisms such as brine shrimp. Human activities have affected the succession process in the lake, leading to the growth of the bottom and a reduction in the area of the lake.
