A recent study assessed heavy metal concentrations in the sediments of Hurghada and Marsa Alam along the Egyptian Red Sea coast. The research aimed to understand the distribution, sources, and potential ecological risks associated with these contaminants.
Researchers collected surface sediment samples from various sites. They analyzed the concentrations of iron (Fe), manganese (Mn), zinc (Zn), nickel (Ni), copper (Cu), lead (Pb), and cadmium (Cd). Total organic matter and carbonate content were also evaluated to assess the relationship between metal concentrations and sediment composition.
The study found varying metal concentrations across sites. Hurghada showed reduced levels of Fe, Mn, Zn, and Cu, but higher levels of Ni, Pb, and Cd. Principal component analysis linked metals like Cu, Zn, Ni, and Pb in Hurghada to anthropogenic sources. Pollution indices indicated moderate pollution with Pb but no significant ecological or health risks.
The assessment suggests that current heavy metal levels do not pose significant risks. However, continuous monitoring is recommended to detect future changes and implement environmental management strategies.
