摘要

This study evaluates the potentially toxic elements (PTEs) in sediments and barnacles from two distinct locations along the northern Red Sea coast. Geoaccumulation (Igeo), contamination factor (Cf), soil pollution index (SPI), modified contamination degree (mCdeg), pollution load index (PLI), and potential ecological risk index (PERI) revealed that sediments in Sharm el-Sheikh were richer in Fe and Mn, whereas Hurghada exhibited higher levels of Cu, Zn, Pb, Ni, and Cd, linked to anthropogenic activities. While most contamination levels were within safe limits. Perforatus perforatus (Bruguière, 1789) exhibited higher bioaccumulation of Fe, Mn, Pb, Cd, and Co, while Tetraclita squamosa (Bruguière, 1789) showed elevated Cu, Zn, and Ni levels. Bioaccumulation coefficients and statistical analyses underline their effectiveness as biomarkers for monitoring pollution. The study recommends further research to enhance the use of barnacles as biomarkers and emphasizes the importance of continuous monitoring for environmental and health risk management.
