Assessment of heavy ####ls pollution in Sudanese harbours along the Red Sea Coast
The levels of some heavy ####ls in sediments of two harbours along the Sudanese
Coast of the Red Sea were examined and reported for the first time.
A total of thirty-six surface sediment samples were collected from Port-Sudan and Sawakin harbours.
Part of each sample was partitioned into five fractions with grain-size ranges
of 1000–500, 500–250, 250–125, 125–63 and less than 63 μm. The Mn, Fe, Ni, Cu, Zn and Pb
concentration in bulk samples and sub-samples were determined by atomic absorption spectrophotometry.
The spatial distribution pattern of heavy ####l content of crustal origin in the sediments is more uniform
in Port-Sudan harbour than in Sawakin harbour. The granulometric normalization revealed that
some sites in Port-Sudan harbour and one site in Sawakin harbour have been exposed to
different levels of heavy ####l contamination, which probably originated from ships, industrial and domestic activities.
