A total of 25 randomly purchased bread samples were analyzed in this study from 25 different bakeries in Tajoura city. Bread in Libya is highly consumed among all socioeconomic groups; it is mainly consumed in breakfast, dinner and school meals. Potassium bromate is the most popular additive used in bakery industry worldwide. Bakeries in the US used Potassium bromate as bread improver since 1914 to increase bread volume and texture and improve bread production. The main aim of this study is to assess the safety of bread by the measurement of residual potassium bromate using a rapid and reliable method and to investigate the level of compliance to the ban fourteen years later. This method is based on the reaction between bromate and iodide in acidic medium to produce iodine (I2). The absorbance of I2 was measured spectrophotometrically at 488nm. The calibration curve was linear (R2=0.9996) over the range 1.0 – 5.0mg/L of potassium bromate. Despite the ban of potassium bromate in Libya since 2005 due to its classification as a potential carcinogen it is still detected in local bread loaves. All samples showed high levels of potassium bromate to be 300 to 1333 more than the permissible level set by the American Food and Drug Administration (FDA) which is highly toxic for consumers and could threaten their health over prolonged regular consumption. A continuous pursuance and implementation of the ban on use of potassium bromate in baking industry in Libya is recommended. arabic 11 English 67

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

One of the Libyan Faculty of Education exit requirements is the graduation research project. Review of the current literature shows that there exists a dearth of literature on the quality of the graduation project in the Libyan context. To address this shortcoming, the present study investigated the opinions of the faculty members of the Faculties of Education at various Libyan public universities on achieving quality standards in the graduation research projects. The design of the study was exploratory sequential mixed methods as we gathered both quantitative and qualitative data to get accurate and detailed picture of the Libyan teacher-educators’ views on fostering quality in the graduation research project. The context of the study is the Faculties of Education at eight Libyan universities. The participants were 62 Libyan teacher-educators who were faculty members at the Libyan Faculties of Education. Data were collected through documents, questionnaires, and follow up interviews. The results showed that the participants’ views were opposite to the document analysis and revealed that the participants were not sure whether the regulations covered all the points related to the graduation research projects, so they preferred to be neutral. They also perceived several factors as the issues that hindered the quality of the graduation research projects. The participants suggestions as ways of fostering quality in the graduation research projects included achieving quality by following the quality standards described by the quality assurance department among other suggestions. arabic 21 English 111
