Abstract

The aim of this work is to gather information on the distribution of some metals in the surface sediments of the Kwar Katib lagoon, northern side of Hodeidah city, Yemen, Red Sea. Twenty samples were collected from this lagoon. Heavy metals such as ( Fe, Al, Mn, Cu, Ni, Zn, Pb, Cr, Ti, La, Sr, Ba, Co and As) have been analyzed in the samples. The concentration of organic matter is related by fine sediments and biological activities. The enrichment factors (EF), contamination factor (CF) geoaccumulation index (Geo-I) have been calculated as a criterion to assess if their concentrations represent contamination levels or can be considered Unpolluted and unpolluted - moderately polluted. Analytical results have been elaborated by using a Geographical Information System (GIS) software to show metals accumulation areas. Statistical analysis results have showed metals distribution in the Kwar Katib lagoon is principally influenced by Hodeidah port activities in the southern lagoon.

Keywords: heavy metals, Sediment, contamination lagoon, Kwar Katib, GIS, Red Sea
