Risks Assessment of Potentially Toxic Elements’ Contamination in the Egyptian Red Sea Surficial Sediments

The potential impact of tourism, industrial, and urban activities on Egypt’s Red Sea coastline, which is well-known for its economic environmental importance, was investigated at fifteen coastal sites. In the present study, concentration cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), zinc (Zn) in marine sediments from these sites, determined using Inductively Coupled Plasma Mass Spectrometers (ICP-MS). detail, various pollution indices, statistical analyses, spatial distribution patterns were used to assess status, impacts human activities, ecological risks, sources potentially toxic elements (PTEs) surface sediment. A detailed comparison with up-to-date data conducted. These composed predominantly fine very sands. Mean grain size typically depends source sediment following two prime sources: terrigenous (autochthonous) biogenic (allochthonous). detected PTE mean concentrations as follows: Fe > Mn Zn Cr Ni Pb Co Cu Cd. Multivariate analysis results revealed their close association. Cd levels studied area have been slightly impacted by anthropogenic inputs. According calculated although a minimal or moderate contamination degree study area, it that there low risk. high risk centered middle around phosphate mining related activities. More attention should be given Cd, Ni, main factors.
