Assessing some heavy metals pollutions in sediments of the northern Persian Gulf (Bushehr province)

Abstract

Background: Land and water pollution by heavy metals is a universal issue. Although the pollution affects all countries, but its range and severity vary hugely. The pollution of the marine environment by heavy metals is a worldwide problem. Marine sediments can be sensitive indicators for monitoring contaminants in aquatic environments. Methods: The concentration of 10 elements (As, Cd, Cr, Cu, Al, Fe, Ni, Pb, Sb, and Zn) was determined in the sediments of four shoreline stations including Imam Hassan port, Ameri port, Bushehr port, and Nayband Bay at the west Persian Gulf from March to December 2017. The elements were measured by inductively coupled plasma mass spectrometry (ICP-MS). Data were analyzed using SPSS version 16. Results: The contamination of the sediments was assessed based on the geoaccumulation index (Igeo) and enrichment factor (EF). Spearman correlation matrix was calculated between all the trace metals and major elements as well as corresponding sampling regions. Statistically significant inter-elemental correlations (e.g., Cr-Fe, Cr-Al, Cr-Ni, Cr-Zn, and Cr-Cu) were found between some metals. High EF levels for Fe, Al, and Pb suggest that metals in the sediments of the northern Persian Gulf could have originated from anthropogenic sources. Conclusion: The contamination pattern of sediments is affected by factors such as sedimentation patterns, physical and chemical properties of the sediments. For example, sediments with fine-grained and high surface area-to-volume ratio can act as good absorbents for many pollutants.

Evaluation of trace elements contaminations in muscles of Rutilus kutum (Pisces: Cyprinidae) from the Southern shores of the Caspian Sea

“…The Caspian Sea is the largest lake in the world (12,13). It is under pressure from environmental threats such as discharge of industrial and agricultural effluents and growing urbanization in most riparian countries of the Caspian Sea (14,15). The TEs concentrations in the fish muscles, as the main consumable part for human consumption, must be treated with utmost concern, although their liver and skin are also consumed to some extents.…”

Influence Des Activites Anthropiques Sur La Degradation De La Qualite Des Sediments De La Lagune Ouladine (Sud-Est De La Côte d’Ivoire)

“…Les ETM ont tendance à s'accumuler dans les sédiments, une fois, introduits dans le milieu aquatique, et vont ainsi jouer le rôle de puits de contaminants. À cet égard, les sédiments peuvent être des indicateurs sensibles pour la surveillance des contaminants dans les milieux aquatiques (Bibak et al, 2018) Cette contamination par les ETM stockée dans les sédiments deviendra une source de perturbation de l'écosystème aquatique, même après la prise de mesures destinées à stopper ou à réguler les apports (Tessier, 2012).…”

Assessment of heavy metals concentrations in the soil of Mongla industrial area, Bangladesh

“…Recently, Bibak et al assessed the contamination level of sediments in Bushehr province (Iran) based on the geoaccumulation index (I geo ) and enrichment factor (EF). The higher level of EF was observed for Fe and Pb, indicating that the sediments contamination was mainly due to anthropogenic activities (16). Ediene and Umoetok examined the concentration of heavy metals in the soil of Cross River State (Nigeria) and reported that the level of Zn and Pb in the soil was above the permissible limits, whereas the level of Cu was within the safe limit (17).…”
