摘要

沙姆沙伊赫位于亚喀巴湾的南部入口，是一个重要的旅游目的地，以其温和的气候和对环境倡议的承诺而闻名，特别是在2022年举办了第27届联合国气候变化大会。本研究评估海滩沉积物中的重金属污染，以评估环境和人类风险。抽样是在两个热门旅游区沙姆沙港和玛雅湾进行的。沉积物样品显示不同浓度的铁、锰、锌、铅、铜和钴，都在安全水平内。非致癌性和致癌性风险通过慢性每日摄入量和危害指数进行评估，揭示摄入是暴露途径中风险最高的。然而，根据国际标准，研究区内的海滩沉积物可安全供成人及儿童作康乐用途。统计分析确定了低水平的自然和人为污染源，强调需要不断进行环境监测，以维护这一重要旅游区的环境质量，并通过实施可持续的废物管理做法、管制旅游活动和保护海洋生态系统，确保公众健康和安全。

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.

期刊介绍： Marine Pollution Bulletin is concerned with the rational use of maritime and marine resources in estuaries, the seas and oceans, as well as with documenting marine pollution and introducing new forms of measurement and analysis. A wide range of topics are discussed as news, comment, reviews and research reports, not only on effluent disposal and pollution control, but also on the management, economic aspects and protection of the marine environment in general.
