“…Contamination by trace metals is a serious threat in aquatic systems due to their level of toxicity, abundance, persistence in the environment and subsequent accumulation in aquatic milieu (Bessa et al., 2018; Ekoa Bessa et al., 2018). In some studies, it was reported that the contamination of flooded areas by trace elements includes natural and anthropogenic sources such as geological weathering and erosion (Kaushik et al., 2009; Hanif et al., 2016), atmospheric deposition (Huang et al., 2009; Xiong et al., 2016; Ekoa Bessa et al., 2018), disposal of liquid effluents, fertilizers, and pesticides (Sun et al., 2018; Zhou et al., 2018; Jiang et al., 2019), terrestrial run-off and chemicals originating from various urban, industrial and agricultural activities (Xiao et al., 2013; Zahra et al., 2014; Mimba et al., 2018; Al-Hadithy et al., 2018; Chen et al., 2019). Sediments are the source of substrate nutrients, micro- and macro flora and fauna have a significant role in the aquatic habitat (Jain et al., 2004; Guo et al., 2010; Bat and Özkan, 2019; Gao et al., 2019).…”

In this investigation, the level of toxic metals (Cd, Pb, Hg, Cu, Ni, Al, Zn and U) was determined in sediment samples from two watersheds (Kienké and Tchangué) in the Abiete-Toko gold district, southern Cameroon. The potential contamination and toxicity of studied metals was determined by evaluating enrichment factor (EF), geo-accumulation index (Igeo) and ecological risk assessment (ERA). Considering the spatial distribution patterns, metal concentrations were lower than the average shale values, except for Cu and Ni of site 4 in the Kienké watershed and only Ni in the Tchangué watershed. In this study, the EF and Igeo values revealed that sediments were moderately polluted by Ni and Cu and unpolluted by other metals. The evaluation of the ERA based on ecological risk index (RI), ecological risk factor (Er), contamination factor (CF) and pollution load index (PLI) revealed that the sediments from the Abiete-Toko watersheds have significant to very high ecological risk assessment and are generally unpolluted by trace metals and U, except for Ni and Cu. Little quantities of heavy metals with low U levels and distribution were found at the sites close to the vicinity of artisanal mining and peri-urban areas. This proximity reveals that artisanal gold mining activities, agricultural runoff, and other anthropogenic inputs in the study area are probable sources of slight metal contamination. However, the non-use of toxic effluents for gold mining and pesticides for agriculture can be an advantage of the unpolluted status of the watersheds. The physical degradation of the ecosystem through excavations, wells and other stream diversion methods is expanding in the zone. Appropriate measures should be taken by artisans to rehabilitate the gold mining sites, to ensure appropriate treatment of wastewater and non-use of toxic effluents into nearby tributaries.

“…Heavy metals are a major worldwide pollution threat due to their toxicity and dispersion characteristics that can be enriched in living organisms (Bessa et al 2018;Ekoa Bessa et al 2018). In aquatic environments, the main sources of heavy metal entry are storm and erosion (Hanif et al 2016), atmospheric sediments, wastewater effluents, fertilizers, and pesticides (Sun et al 2018;Zhou et al 2018;Jiang et al 2019), land surface runoff and chemicals from municipal, industrial and agricultural activities (Xiao et al 2013;Zahra et al 2014;Mimbo et al 2018;Al-Hadithy et al 2018;Chen et al 2019). Sediments are a source of nutrients, micro and macro flora and fauna that play an important role in aquatic habitats (Jain et al 2004;Guo et al 2010;Bat and Ozkan, 2019;Gao et al 2019).…”

<p>This study aimed to evaluate the pollution level of Ni, Pb, Cd, V, and Hg in the sediments of Musa Estuary and its four main tributaries namely Majidieh, Zangi, Semaili, and Merimos (collectively known as Mahshahr estuaries) in summer and winter 2019 using sediment quality indices. In each tributary, 4 stations were chosen to represent the estuary condition. One control point was also considered at the mouth of the estuary (17 stations in total). 51 sediment samples were collected using the Van Wien Hydrobius grab sampler and measurements were performed utilizing the ICP-MASS device. The heavy metals concentration was ordered as Ni> Pb> Cd> V> Hg and tributaries followed the order of Majidiyeh> Samaili> Zangi> Merimos> Musa's mouth (control point) in terms of heavy metal concentration in both seasons. Heavy metal concentrations were positively and significantly correlated with electrical conductivity and pH (P <0.05). The potential ecological risk (Er) was low for Ni, Pb, and V, moderate for Cd (except for Musa's mouth in summer (27.33)). Hg had low risk in Zangi Tributary and Musa's mouth in summer and medium risk in other tributaries in winter. The ecological risk index (RI) showed considerable risk in Zangi Tributary and Musa's mouth in both seasons and high risk in Merimos, Majidieh, and Samaili tributaries. According to the pollution load index (PLI), the sediments of Mahshahr estuaries showed no pollution in summer and moderate pollution in Majidiyeh and Smaili tributaries in winter. The Nemro Integrated Pollution Index ranged from 8.62 to 20.04 in summer and 9.15 to 21.53 in winter Mahshahr estuaries which indicate its high pollution potential. The findings of this research and those of previous studies alarm increasing levels of heavy metals’ content in the sediments of Mahshahr estuaries over the past years.</p>

“…Çökel üzerindeki birkaç santimetrelik kısım sürekli değişen güncel kirliliği yansıtırken daha derinde olan dip çökeller ise, geçmiş jeolojik tarihlerdeki kirlilik ile ilgili bilgi vermektedir [9][10][11]. Ağır metallerin sebep olduğu çevre kirliliği su, hava ve doğrudan toprak kirliliğine yol açan madencilik çalışmaları, gübre ve pestisitler, sanayi atıkları ve hidrokarbon yanma ürünleri ile toprağa ulaşabilmektedir [12][13][14]. Eser miktarda bile olsa gümüş (Ag), arsenik (As), kadmiyum (Cd), krom (Cr), kurşun (Pb), mangan (Mn), civa (Hg), nikel (Ni), selenyum (Se), çinko (Zn) gibi elementler hem ekolojik denge hem de insan sağlığı açısından olumsuz etkilere sahiptir [15][16][17].…”
