“…Compared with coastal areas of the other regions, the AVS concentrations in this study were wider than those recorded in Laizhou Bay ), Shen'ao Bay (Du et al 2011), Zhangjiang Estuary, Fujian (Jingchun et al 2010), Pearl River Estuary (Fang et al 2005), Jinzhou Bay (Hansen et al 1996), Futian mangrove, Shenzhen Bay (Chai et al 2015), Huanghe Estuary (Wu et al 2007), north area of the Bohai Bay (Jiang et al 2005), Yangze River Estuary (Sun et al 2009), Mudflat, Zhangjiang Estuary (Jingchun et al 2010), Zhangjiang Estuary (Jingchun et al 2010), and southern East China Sea continental slope (Lin et al 2002). All of these studies did not perform in industrial and high-polluted areas; hence, it is expected to have lower concentration levels of AVS compared with this study that was conducted in heavily industrialized area.…”

“…Younis et al studied the lagoon Maryut that suffers from almost all possible environmental problems and to quite an extreme degree from various sources, industrial and urban untreated sewage (Qalaa and Umum drains). The findings of SEM were higher than the corresponding values for the sediments in Leizhou Peninsula (Li et al 2014a, b, c), Zhangzi Island, southwestern coastal Laizhou Bay and Laizhou Bay , Shen'ao Bay (Du et al 2011), Zhangjiang Estuary, Fujian (Jingchun et al 2010), Pearl River Estuary (Fang et al 2005), Jinzhou Bay (Hansen et al 1996), Futian mangrove, Shenzhen Bay (Chai et al 2015), Huanghe Estuary (Wu et al 2007), north area of the Bohai Bay (Wu et al 2007), Yangze River Estuary (Sun et al 2009), Mudflat, Zhangjiang Estuary (Jingchun et al 2010), Forest edge (Jingchun et al 2010), Zhangjiang Estuary (Jingchun et al 2010), Forest, Zhangjiang Estuary (Jingchun et al 2010), southern East China Sea continental slope , and Jiaozhou Bay (Huo et al 2001), all in China. The results in the present study were also higher than those recorded in the south coast of São Paulo in Brazil (Nizoli and Luiz-Silva 2012), Douro Estuary in Portugal (Mucha et al 2005), Guadalete River Estuary in Spain (Campana et al 2005), and lagoons (Burullus and Manzalah) in Egypt (Younis et al 2014).…”

Sediment samples from the coastal area of Asaluyeh harbor were collected during autumn and spring 2015. The acidvolatile sulfide (AVS) and simultaneously extracted metals (SEMs) were measured to assess the sediment quality and potential ecological risks. The average concentrations (and relative standard deviation (RSD)) of AVS in the industrial sediments were 12.32 μmol/g (36.91) and 6.34 μmol/g (80.05) in autumn and spring, respectively, while in the urban area, these values were 0.44 μmol/g (123.50) and 0.31 μmol/g (160.0) in autumn and spring, respectively. The average concentrations of SEM (and RSD) in the industrial sediments were 15.02 μmol/g (14.38) and 12.34 μmol/g (20.65) in autumn and spring, respectively, while in the urban area, these values were 1.10 μmol/g (43.03) and 1.06 μmol/g (55.59) in autumn and spring, respectively. Zn was the predominant component (34.25-86.24 %) of SEM, while the corresponding value for Cd, much more toxic ingredient, was less than 1 %. Some of the coastal sediments in the harbor of Asaluyeh (20 and 47 % in autumn and spring, respectively) had expected adverse biological effects based on the suggested criterion by United States Environmental Protection Agency (USEPA), while most stations (80 and 53 % in autumn and spring, respectively) had uncertain adverse effects.

“…Knowledge of the total PTE content in soils and sediments is not adequate to assess their potential ecological risk (Pignotti et al 2018). Analysis of simultaneously extracted metals (SEM) coupled with the acid-volatile sulfide (AVS) content represents a useful approach to determine the potential bioavailability of trace metals (Chai et al 2015). Generally, PTEs in anoxic sediments are considered non-toxic due to the formation of stable and insoluble metal sulphides, resulting in low PTE potential risk.…”

A total of 120 sediments from 12 cores of Portman Bay (SE Spain) were studied to assess the degree of contamination and ecological risk related to potentially toxic elements (PTEs) by combining a geochemical and mineralogical characterisation with the assessment of the bioavailable forms of trace metals (As, Cd, Cu, Fe, Pb, Zn). With this purpose, sediment contamination was assessed by total and water-soluble content, and potential bioavailability by the simultaneously extracted metals and acid-volatile sulphides (SEM-AVS) approach, and by an oral bioaccessibility extraction procedure. The sediments are essentially sandy (>80%). The most important minerals are: iron phases such as siderite, iron oxides and hydroxides and pyrite; clay minerals such as clinochlore, greenalite and

It plays a vital role in the provision of drinking water, irrigation, and industrial use throughout its watershed [11–13]. It can be divided into three distinct geomorphologic basins: the upper, middle, and lower Sebou.…”

The discharge of large quantities of industrial and domestic effluents into the estuaries, with or without treatment, has led to an increase in the amount of micropollutants present in the sediments. In this study, we have assessed the quality of sediments of Sebou river studying the physicochemical parameters, percentage of organic matter, mineralogy, and trace levels of metal elements trapped in the sample sediments of Sebou river. The sediments samples were collected from the upstream of Fez river, confluence between the Fez river and the Sebou river, Ain Nokbi river, and edge of Sebou river, where wastewaters from the city of Fez are discharged. The sediments samples were characterized by scanning electron microscopy, X-ray diffraction, and Fourier Transform Infrared Spectroscopy, while trace levels of metallic elements, Calcium, Zinc, Copper, Cadmium, Iron, and Nickel, were determined by the ICP-AES analysis. The obtained results show that there is a significant change in the values of the studied metals which is probably due to industrial effluents. Indeed, the metal content in the sediments reaches particularly high values exceeding the limit recommended by WHO. These results suggested that the pollution by metallic industrial effluents discharged without treatments poses potential threat to the receiving rivers and may represent a danger for humans which are exposed to pollutants due to the numerous uses of such river waters.
