“…The average concentration of Cu (43.06 µg g -1 ) was higher in comparison to the most studies carried in coastal areas of the Arabian Gulf and the Red Sea. Similarly, the average concentrations of Cr, Cd and Ni were also found to be greater than the previous studies in the Arabian Gulf [49,50]. In addition, the average concentration of Pb (26.61 µg g -1 ) was higher than those recorded in some areas reported in the previous studies except for Shriadah [49] and Usama et al [51] in Abu-Dhabi and Farasan Island, respectively.…”

AbstractTo assess trace element concentrations (Zn, Cu, Pb, Cr, Cd and Ni) in the mangrove swamps along the Saudi coast of the Arabian Gulf, thirteen samples of surface sediment and leaves of grey mangrove, Avicennia marina were collected and analyzed. The detected trace element contents (μg g-1) in surface sediments were in the following descending order according to their mean values; Cr (49.18) > Zn (48.48) > Cu (43.06) > Pb (26.61) > Ni (22.88) > Cd (3.21). The results showed that the average concentrations of Cd and Pb exceeded their world average concentration of shale. The geo-accumulation, potential ecological risk and toxicity response indices demonstrated that trace elements have posed a considerable ecological risk, especially Cd. The inter-relationships between physico-chemical characters and trace elements suggests that grained particles of mud represent a noteworthy character in the distribution of trace elements compared to organic materials. Moreover, the results revealed that Zn was clearly bioaccumulated in leaf tissues A. marina. Dredging, landfilling, sewage effluents and oil pollution can be the paramount sources of pollution in the area under investigation.

“…There are different studies that showed geoaccumulation index values for Pb and Se was higher than 5 (strongly polluted) in the sediment from Persian Gulf (Karbassi et al 2008; Saeedi and Karbassi 2006; Hosseini et al 2014b; Raeisi Sarasiab et al 2014; Nowrouzi and Pourkhabbaz 2014;Vaezi et al 2015; ZareZadeh et al 2017).

Persian Gulf is one of the most important water sources in the economically developed south part of Iran, and metal pollution is a major concern for the Gulf. The bioavailability and distribution of selenium (Se) and lead (Pb) between muddy and sandy sediments from four estuaries along the Persian Gulf were analyzed. The geoaccumulation index and enrichment factor for metals and correlation between particles size with metals concentration were studied. The average concentration of metals in sediment was ranged 0.08–1.14 µg/g for Se and 0.32–4.37 µg/g for Pb in all estuaries, with the highest concentrations in Musa estuary. The results showed there was positive correlation between particles size of sediment with metals concentration. The highest of metal concentration was absorbed in silt (< 63 μm) sediment, followed by extremely fine sand (63–125 μm), fine sand (125–250 μm), medium sand (250–500 μm) and coarse sand (500–1000 μm), respectively. The organic matter and carbonate in the muddy sediment are higher than sandy sediment, and they had high specific storage capacity for accumulation of heavy metals. The result of Pearson correlation (r) for organic matter and metal was 0.78 for Se and 0.67 for Pb, and for carbonates and metal was 0.54 for Se and 0.61 for Pb. The values of EF in all estuaries show that the enrichment of sediment by heavy metals was by anthropogenic activities such as discharge of petrochemical and oil industrial. Geoaccumulation index indicates that the sediment in the Ahmadi and Ghanam estuaries was unpolluted to moderately polluted, while in the Arvand river is moderately to strongly polluted, and in the Musa estuary is extremely polluted.

“…In developing countries in general and in Turkey in particular, ecotoxicological assessments and studies to determine background values are scarce, especially for sediments. Therefore, for the purposes of this study, globally accepted SQGs were used instead of ecotoxicological results [37][38][39][40] , and Average Shale Values (ASVs) were used instead of background values [41][42][43][44][45] . SQGs include criteria designed to assess sediment quality and the ecological risks associated with heavy metals 46 .…”

the concentrations and sources of heavy metals in shallow sediments in Lake Bafa were investigated. the concentrations of nine heavy metals and the total organic carbon content in sediment samples were determined for between Summer 2015 and Spring 2016. The mean contents of heavy metals were in decreasing order fe > Mn > ni > cr > Zn > cu > co > pb > cd. Sediment quality guidelines indicate that Cr, Cu, and Ni pose a considerable threat to the aquatic ecosystem in Lake Bafa. Site L3 was found to be contaminated with cd, cr, and ni, and the pollution load indices suggest that these metals had anthropogenic sources. the sediment samples were notably enriched with cd and ni. there is no consistent trend for seasonal effect in terms of the sample locations. However, at all sampling points, an increase in heavy metal concentrations was observed in the autumn. the results of a multivariate analysis indicate that the sources of co, cu, fe, Mn, pb, and Zn were all natural, the sources of cd were anthropogenic, and the sources of ni and cr were both anthropogenic and natural. these results highlight that cd, cr, and particularly ni represent the most serious threat in terms of heavy metal pollution in the ecosystem of the lake. Heavy metals mainly enter aquatic environments as a result of a variety of human activities (e.g., agriculture, combustion, corroded underground pipes, industrial plants, sewage, smelting, and vehicles) 1-3. Exposure to heavy metals has been linked to various negative health effects, including cancer, behavioural problems, impaired intelligence, developmental problems, kidney damage, and miscarriage or stillbirth 4. Heavy metals are not readily degraded in the environment, and those that enter a water body can remain there for some time. They are usually found in low concentrations in aquatic systems 5 , and high concentrations of heavy metals in sediments can indicate anthropogenic rather than natural sources 6,7. Heavy metals are poorly soluble in water, so predominantly sorb to suspended particles that then settle as sediment 8. Heavy metals can thus enter the food chain in the aquatic environment, and become available for accumulation in biota 9. Fish, which are at the top of the food chain and are an important food source for humans, can accumulate heavy metals in their tissues 10 , and this characteristic makes them an effective indicator of pollution 11. Accordingly, assessment of pollution from heavy metals in sediments in the environment is very important in terms of its effects on aquatic organisms and human health 12. Lake sediments are a sink for heavy metals 13,14 , and heavy metal concentrations are generally higher in sediment than in water 15. Indeed, concentrations of heavy metals in water are sometimes lower than detection limits, meaning that sediment should be analysed to assess levels of contamination by heavy metals in the aquatic system 16-18. Lake sediments mostly act as a sink for heavy metals; on the other hand, they can also act as a source to the overlying water 19,20. C...
