摘要

本研究旨在利用多种污染指数,评估 2021 年期间埃及红海 El-Qusier 和 Safaga 市污染对沉积物质量的影响以及相关风险。为此,我们评估了金属污染指数(MPI)、污染因子(Cf)、污染负荷指数(PLI)、污染安全指数(CSI)和人为污染指数(Anp%)。此外,致癌和非致癌风险也被用于人类健康危害。结果表明,锰和铁的浓度最高,而镉的浓度最低。El-Quseir 市的沉积物中发现了以下金属离子:铁 > 锰 > 镍 > 锌 > 铜 > 钴 > 铅 > 镉:铁 > 锰 > 锌 > 镍 > 铜 > 铅 > 钴 > 镉。MPI > 1,这表明研究地区的重金属污染情况令人担忧。此外,Cf HI 皮肤。不同途径的CSR记录为皮肤>摄入,其中所有途径的总CSR被认为是有害的,致癌风险令人担忧,高于1×10-6-1×10-4的参考范围。总之,所研究的重金属在所有评估地点都会对环境造成危害。

A comparative study of the risk assessment and heavy metal contamination of coastal sediments in the Red sea, Egypt, between the cities of El-Quseir and Safaga

This study aimed to assess the influence of pollution on the quality of sediments and the risks associated with El-Qusier and Safaga Cities, Red Sea, Egypt, during 2021, divided into four sectors, using multiple pollution indices. To achieve that, we evaluated the metal pollution index (MPI), contamination factor (Cf), pollution load index (PLI), contamination security index (CSI), and anthropogenicity (Anp%). Moreover, carcinogenic and non-carcinogenic risks are used for human health hazards. Results indicated that Mn and Fe recorded the highest concentrations, whereas Cd had the lowest. El-Quseir City sediments were found the following metal ions: Fe > Mn > Ni > Zn > Cu > Co > Pb > Cd, where the order in the Safaga City was: Fe > Mn > Zn > Ni > Cu > Pb > Co > Cd. MPI > 1, this is alarming in the study area due to heavy metal pollution. In addition, Cf < 1 in all metals except Cd with contamination degree CD ranged from low to considerable contamination in El-Qusier city. In contrast, contamination ranged from significant to very high in Safaga city. PLI < 1 is lower than the reference at all monitored stations. CSI values ranged from relatively low to moderate. Besides Cd, data reflect each element's low environmental danger (EriMe40). This study's risk index (RI) is low to moderate in Sector 1 and high to extremely high in Sector 2. HQ and HI index < 1 means it is safe for human health in order: HI ingestion > HI dermal. CSR for different pathways was recorded as dermal > ingestion, in which total CSR for all paths is considered harmful, and the cancer risk is troublesome and higher than the reference ranges of 1 × 10–6–1 × 10–4. In conclusion, the examined heavy metals provide environmental hazards across the assessed locations.
