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

Spectrophotometric determination of iron in dietary supplements in Libyan market

In most cases dietary supplements especially in Libya are consumed without prescriptions and the public has very limited any awareness of their health risk. The lack of quality control on numerous brands of dietary supplements in pharmacies of Libya today may result in a serious health problem. The aim of this study is to determine the iron content using a fast and accurate method for quality control of some imported dietary supplements, based on spectrophotometric measurement of iron after complexation with 1, 10-phenanthroline in an acidic medium. Eight types of vitamin supplementary tablets were randomly collected from the Libyan market and analyzed for the iron content. The analysis showed an average value of 61mg Fe/pill for the range of 40.07-112.63 mg Fe/pill. Results showed that 75% of the samples were lower in iron content than that recorded on the dietary products. arabic 9 English 71
