摘要：

The levels of some heavy metals 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 mu m. 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 metal 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 metal contamination, which probably originated from ships, industrial and domestic activities.
