“…The coastal stretch is usually the most environmentally threatened areas, and it is an important issue to inspect the reasons of such ecological worsening. Many endeavors successfully created valuable use of micro-organisms (i.e., benthic foraminifera) as a proxy to bio-monitor changes in the coastal environments over the previous few centuries (Samir and El-Din 2001 ; Geslin et al 2002 ; Frontalini et al 2009 , 2013 ; Li et al 2021 ; El-Kahawy et al 2021 ; Balachandar et al 2023 ). For instance, certain models have been proposed scrutinizing faunal relative abundance and diversity in such environments.…”

Twenty-nine sediment samples were collected from the Hurghada Bay, a heavily polluted bay on the Red Sea of Egypt, to inspect the environmental quality status and anthropogenic consequences on benthic foraminifera. Some foraminiferal species showed deformations in their apertures and coiling directions as a response to environmental stresses. In addition, the FoRAM index, an index used for evaluating the growth of coral reefs, indicated a hazard in the proximity of nearshore stations. To elucidate the relationships between the biological response and chemistry of sediments, eight heavy metals concentrations (Cu, Cd, Zn, Pb, As, Cr, Ni, and Mn) were analyzed using inductively coupled plasma–atomic emission spectrometers (ICP-AES). Interestingly, two groups of benthic foraminiferal associations were illustrated using multivariate statistical analyses. Group I have extremely high heavy metal concentrations, an enriched total organic matter (TOM)%, high deformation percentages, and mud content. Moreover, it is dominated by Ammonia tepida which is regarded as an opportunistic species. Group II includes low to moderately polluted stations, highly enriched living foraminiferal assemblages, and is dominated by the sensitive rotaliids Neorotalia calcar and Amphistegina lobifera. Alternatively, four geochemical indices, EF, CF, Igeo, and PLI, are used to assess the contamination level that shown ominous spots for the nearshore stations of the Hurghada Bay. The pollution indices (HQ and HI) were also conducted to evaluate the risks of carcinogenic heavy metals on human health. Our findings demonstrated that ingestion and dermal exposure have greater carcinogenic hazards for adults and children than inhalation. The lifetime carcinogenic risk (LCR) is significantly higher than the permissible limit and follows this order: Pb > As > Cr > Cd > Ni. To that end, developing strategies to lessen the negative impact of pollution on human health and/or the Red Sea’s biodiversity is an inevitable issue in the present day and future.

“…Several species have characteristics that allow them to detect the impact of disturbances in the marine environment, presenting effects at the molecular, biochemical, histological, physiological, and morphological levels [ 37 ] and even at community and ecosystem structure levels [ 38 , 39 ]. Therefore, strategies for the assessment of coastal pollution include two approaches: the monitoring of substances in sediment, water, and suspended material and the use of sentinel organisms, such as macroinvertebrates [ 40 , 41 ], foraminifers [ 42 ], algae [ 43 , 44 ], polychaetas [ 45 ], ascidians [ 46 ], echinoderms [ 47 , 48 ], bivalves [ 49 , 50 , 51 , 52 ], crustaceans [ 53 , 54 , 55 , 56 ], and fish [ 57 , 58 , 59 ], among others sensitive to environmental changes.…”

Coastal zones sustain extensive biodiversity, support key processes for ocean dynamics, and influence the balance of the global environment. They also provide resources and services to communities, determine their culture, and are the basis for their economic growth. Cartagena Bay in the Colombian Caribbean is the place of the establishment of one of the country’s main cities, which has a great historical and tourist attraction, and it is also the location of the main commercial port and a great variety of industries. Historically, it has been affected by several environmental impacts and intense pollution. This situation has gained the attention of different researchers, so herein is presented a literature review with a systematic approach using RStudio’s bibliometrix on the presence of pollutants and the impact on biodiversity in recent decades, providing a critical analysis of the state of Cartagena Bay and its future needs to ensure its recovery and conservation. In addition, the socioeconomic dynamics related to the environmental state of Cartagena Bay are presented from the framework drivers, pressures, status, impacts, and responses (DPSIR). The update and critical understanding of the sources, fate, and effects of pollution are important not only for the knowledge of the status of this singular ecosystem but also to encourage future research and entrench evidence to support decision makers’ actions. This review highlights that several pollutants that have been detected exceeding sediment quality guidelines, like As, Cd, Hg, and PAH, are also reported to bioaccumulate and cause damage throughout the trophic levels of the coastal environment. In addition, the potential use of sentinel species and biomarkers for their monitoring is discussed. Finally, the factors that cause pollution and threaten the state of the bay continue to exert pressure and impact; thus, there is a call for the further monitoring of this ecosystem and the strengthening of policies and regulations.
