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

Bidong Island is one of the least known islands in terms of birds; very few surveys have been conducted on this island. The island is part of a small archipelago called Bidong Laut, located to the northwest of Kuala Terengganu, on the east coast of Peninsular Malaysia. A total count of 30 bird species, from 19 families and 25 genera were found on this island between 2006 and 2020. Collected data (nine days) were analysed for biodiversity indices. Alpha diversity indices showed variations among sampling years, Simpson 1-D range 0.76–0.89; Shannon (H) range 1.74–2.48; species richness 8–16 species; dominance (D) range 0.11–0.24. Species richness estimators indicate that more species can be added with additional sampling and better coverage of the island area. The relatively low avian species richness compared to other east coast islands is discussed. Further surveys during migration season can reveal the importance of this island as a stop over site for several migratory species.
