Surface sediment enrichment with trace metals in a heavily human-impacted lagoon (Bizerte Lagoon, Southern Mediterranean Sea): Spatial distribution, ecological risk assessment, and implications for environmental protection

Assessment of toxic metal contamination, distribution and risk in the sediments from lagoons used for fish farming in the central region of Peru

“…Compared to other national studies, the concentrations of toxic metals recorded in the sediments of the three lagoons were lower than those recorded in Lake Titicaca [42] . Compared to studies in other regions of the world, the values found in this research were lower than those recorded in the Batticaloa lagoons [3] and Bizerte [18] . From these results, it can be observed that most of the toxic metals evaluated were found in the southern zone of each lagoon.…”

Mediterranean Coastal Lagoons Review: Sites to Visit before Disappearance

“…The bibliographic review has shown that the most studied are the Venice lagoon [28] (more than 1800 publications) and the Mar Menor (about 300) [29]. At a lower level, the lagoons of Thau, Leucate, Bizerte, Tunis, Marano-Grado and Orbetello already have between 300 and 100 publications (Figure 4a) [25,[30][31][32][33][34].…”

Of the most recent published papers, the main topics are related to hydrology, pollution and water quality (Figure 4b), while the remaining third of the publications are related to plankton, fish, sediment and benthos, economic activities and paleoecology.…”

Sediment quality and environmental risk assessment in a Mediterranean coastal system using geochemical and multivariate statistical analyses: the case of Boughrara Lagoon (southeastern Tunisia)

“…Recently, various renewed scientific focus in marine pollution indicated that coastal environments were highly contaminated by organic and inorganic pollutants and especially by metals (Pignotti et al, 2018;Çullu et al, 2020;Kükrer et al, 2020;Lin et al, 2021;El Zrelli et al, 2021;Ferraro et al, 2022;Wang et al, 2022). The Mediterranean Sea is considered as the most threatened ecosystem, subject to significant anthropogenic pressure due to the economic and population development.…”

“…The Mediterranean Sea is considered as the most threatened ecosystem, subject to significant anthropogenic pressure due to the economic and population development. Several recent studies were carried out to evaluate the pollution in various coasts in Tunisia, since they are subject to high anthropogenic pressures Zaaboub et al, 2015;Khedhri et al, 2016;El Zrelli et al, 2017;Ben Mna et al, 2017;Gargouri et al, 2018;Naifar et al, 2018;Mosbahi et al, 2019Keskes et al, 2020Belkahia et al, 2020;Ben Mna et al, 2021;El Zrelli et al, 2021). However, the extent of pollution by metals is not precisely known in the Boughrara lagoon which is located between the southeastern part of Tunisia and Djerba Island, whereas this semi-enclosed lagoon can represent an accumulation basin of pollution.…”
