Study of Some Physical and Chemical Characteristic Properties of Ground Water in Sug al Jumaa area in Tripoli, Libya

ABSTRACT The physical and chemical properties of ground water from thirty wells in Sug al Juma’a area in Tripoli, Libya were analyzed using standard methods. Ground water samples were collected from three locations (Al-Shat Road (A), Sug al Juma’a Road (B) and Arada Road (C)). The physical and chemical parameters such as pH, Total Dissolved Solids (TDS), Total Hardness (TH), Electrical Conductivity (EC), Calcium (Ca2+), Magnesium (Mg2+), Sodium (Na+), Potassium (K+), Chloride (Cl-), Sulfate (SO4 2-), Bicarbonate (HCO3 -), Nitrate (NO3 -) were analyzed to study the present status of the ground water quality. The results were compared to the Libyan Standard No. 82 for Drinking Water and the World Health Organization (WHO). The understudy samples showed significantly higher values of TDS and EC than Libyan Standard and WHO. Permissible limits which may greatly influence the health conditions of the residents of this area. It is concluded from this study that the ground water of the area needs a substantial degree of purification treatment before using for drinking and domestic purposes. arabic 8 English 56

Determination of Some Trace Elements in Different Vinegar Samples from Libyan Market using Inductively Coupled Plasma Atomic Emission Spectrometer ICP-AES

Ten vinegar samples were collected from the Libyan local market in the city of Tripoli. The elements have been investigated were:As, Pb, Cu, Fe and Zn. The samples were treated and prepared according to Indian standard IS 14703-1999, and the measurements have been done by using inductively coupled plasm – atomic emission spectroscopy (ICP-AES) available in the Libyan Petroleum Institute. The analysis indicated that the concentration of Arsenic of all the samples was less than 0.02mg/kg whereas, the concentration of lead is less than 0.03mg/kg. The concentration ranges of Cu, Fe and Zn were 0.11-0.59mg/kg, 0.72-2.67mg/kg and 0.08-0.28mg/kg respectively. The concentrations of the elements AS, Pb, Cu, Fe and Zn are within the limits of a variety of standards such as Libyan, Indian and Pakistani ones. arabic 21 English 134
