Concentration of Heavy Metals in Sediment and Seagrasses Tissue of the Red Sea Coastal Water of the Sudan

A study measuring heavy metal concentrations in sediments and seagrass tissues along the Sudanese Red Sea coast revealed significant pollution levels, particularly at Marsa Dama Dama and Marsa Halout. Marsa Dama Dama showed elevated concentrations of lead (60.5 μg/g), cadmium (0.22 μg/g), and chromium (146.65 μg/g) in sediments, while Marsa Halout exhibited the highest nickel concentration (14 μg/g). Seagrass tissues displayed variable metal uptake, with lead concentrations ranging from 3.9 to 26.25 μg/g, showing significant site-specific differences. The study used atomic absorption spectrophotometry for lead, cadmium, and nickel, and a colorimetric method for chromium, providing critical insights into coastal environmental health in the region.
