Ecological and health risk assessment of Sharm El-sheikh beach sediments, Red Sea coast

Sharm El-Sheikh, located at the southern entrance of the Gulf of Aqaba, is a key tourist destination known for its mild climate and commitment to environmental initiatives, notably hosting COP27 in 2022. This study evaluates heavy metal contamination in beach sediments to assess environmental and human risks. Sampling was conducted at Sharm Port and El-Maya Bay, both popular tourist areas. Sediment samples revealed varying concentrations of Fe, Mn, Zn, Pb, Cu, and Co, all within safe levels. Non-carcinogenic and carcinogenic risks were evaluated through chronic daily intake and hazard indices, revealing that ingestion poses the highest risk among exposure pathways. However, the beach sediments of the study area are generally safe for recreational use by both adults and children according to international standards. Statistical analyses identified low-level natural and anthropogenic sources of contamination, underscoring the need for ongoing environmental monitoring to preserve environmental quality in this vital tourist area and to ensure public health and safety by implementing sustainable waste management practices, regulating tourism activities, and protecting marine ecosystems.
