“…The determination of the total metal content in the bulk sediments of coastal areas of the Arabian Gulf have been carried out in many studies (e.g. El Sayed et al, 2002;Samir et al, 2006;Basaham, 2010;Biati et al, 2012;Elhabab and Adsani, 2013;Al Kahtany et al, accepted for publication).…”

“…Other parameters such as the balance between organic matter production and assimilation as well as its mineralization may play the predominant role. Previous studies on Jeddah coastal sediments (El Sayed et al 2002;Basaham and El Sayed 2001) have shown that OC covaried with the mud content and was inversely related to the carbonate content.…”

“…The concentration of OC in marine sediments is governed by the sediment grain size; it increases with decreasing grain size (Poppe and Commeau 1992;Basaham and El Sayed 2001;El Sayed et al 2002). Generally, fine particles are associated with a relatively high loading of adsorbed organic matter (Buckley and Winters 1992).…”

Surface sediments from the Jizan shelf, southern Red Sea, were analysed for grain size and mineralogical and elemental composition in order to establish their geochemical characteristics. Texturally, sediments are classified into sand and mud; the latter dominates the shelf. Grain size variability and mineralogical assemblages present in the sediments largely control the abundance and distribution of CaCO 3 , organic carbon content (OC) and the major and trace elements. Sand sediments are composed of carbonate material of marine origin and contain high concentrations of Ca, Mg and Sr. Mud sediments are relatively rich in OC and are characterised by high concentrations of Al, Fe, Ti, Mn, Cu, Cr, Co, Ni, V and Ba. Unlike the sand, Mg concentration in the mud sediments seems to be controlled by stronger contribution from non-carbonate material. Factor analysis is applied to identify the variables accounting for most of the variance in the mud sediment samples. Three factors are found to describe about 78% of the variance. The first factor which accounts for 41% of the total variance is the Fe and Mn oxides that reach the area through episodic flooding. The second and third factors are the mud (22%) and the mineralogy (15%) of the sediments, respectively.

The aim of this study is to assess the concentration level of some heavy metals (Zn, Cu and Fe) in the surface sediments of the coastal area from Haql to Yanbu along the Saudi Arabian Red Sea during 2009. The concentration (µg/g) levels range from 4.38 to 73.25 for Zn; 0.0 to 41.25 for Cu; 1263 to 33763 for Fe in lower intertidal sediments. They range in upper intertidal sediments from 5.13 to 63.0 for Zn; 0.0 to 53.75 for Cu, and 2350 to 89350 for Fe. The present environmental status was assessed using, enrichment factor (EF) and Geoaccumulation index (I geo ), to compensate the influence of natural variability in sediment. The results reveal that both metal enrichment factor (EF) and Geoaccumulation index (I geo ) show that the enrichment of Zn and Cu in most of the study area is insignificant. However, with respect to a specific site in study area, stations numbered 3, 10, 12, 14, 15, 16, 18 and 22 are highly enriched with Cu and Zn. The reason behind this enrichment is attributed to human activities along the coastal zone (municipal discharges, industrial development, tourism activities, desalination plants … etc.
