Article Synopsis
- - This study analyzes plastic waste sources and characteristics in different Egyptian environments, including marine (Mediterranean and Red Seas), freshwater (River Nile), and urban areas.
- - Key plastics found are polyethylene and polypropylene in marine areas, polystyrene in the River Nile, and a mix in urban settings, with varying sizes and thicknesses influenced by environmental factors.
- - Degradation rates differ significantly based on location, highlighting the need for specific policies to combat plastic pollution in Egypt, which is important for global conservation efforts.
In Egypt, the distribution of black sand in various coastal regions has been readily apparent by thorough research. Unfortunately, these investigations did not measure radioactivity in black sand, particularly in the vicinity of the Red Sea. Gamma-ray spectroscopy was used to detect the naturally occurring radioactivity from U, Th, K, and Ra in black sand samples from eight locations along the Red Sea coast: Ras Elbehar, Gemsa, Hurghada Elahiaa, Hurghada Titanic, Safaga, Qusier Elsharm Alqbly, Gabal Alrosass, and Marsa Alam.

- Black sand along the Red Sea consists mainly of volcanic and heavy minerals, with unique geological features across various beaches in the region.
- A comprehensive chemical analysis revealed significant variations in elemental compositions, utilizing techniques like XRD and XRF, which helped identify diverse mineralogical profiles at different sites.
- The study highlights the presence of minerals such as Quartz and Magnetite in samples from multiple locations, linking differences in mineral content to the geological makeup of source rocks, thereby contributing to our understanding of the area's geological diversity.
