“…Major heavy metal pollutants found in the mangrove ecosystem are Cadmium (Cd), Chromium (Cr), Copper (Cu), Zinc (Zn), Lead (Pb), Nickel (Ni), Manganese (Mn), Mercury (Hg), Arsenic (As), Cobalt (Co) and Iron (Fe) [34,35,[37][38][39][40][41][42][43][44]. The pollution sources of trace metals are due to anthropogenic inputs such as metal processing, domestic sewage, agricultural and industrial activities [34,37,39,43,45]. The collection of data that studies heavy metal concentration in mangrove estuaries is shown in Table 1.…”

The feasibility of artificial intelligence (AI) as a predictive model for thorough efficacy analysis on environmental pollution applied on mangrove forests are discussed. Mangrove forests are among the most productive and biological diverse ecosystems on the planet. However, due to environmental pollution and climate change, mangrove forests are in serious decline. Despite crucial issues pertaining mangrove forests, the law enforcement on the ecosystem is still dubious due to the lack of evidence and data that could provide accurate analysis and prediction. The main highlight of this review elaborates on pollutant markers in soil, water, and air, by correlating these three aspects to the sustainability of mangrove ecosystem. The research gap identified from this review suggests the application of an integrated environmental prediction system for practical environmental insights. A predictive model for environmental decision-making could be developed by integrating meteorological, climatological, hydrological, atmospheric, and heavy metal concentration to understand the interaction between each factor for an efficient solution of pollutant reduction scheme involving mangrove ecosystems. INDEX TERMS Mangrove estuarine; pollutant interaction; environmental quality modelling; integrated environmental decision system.

“…It plays an important role in preventing wind and waves, puri cation of seawater, and carbon sequestration and storage (Cheng Q et al, 2021). However, rapid urbanization, industrialization, and industrial and agricultural production activities in coastal areas in recent decades have generated a large number of heavy metal pollutants, which ow into the ocean along with surface runoff and directly discharge nearshore, causing serious destruction to mangroves (Jiang R et al, 2020;Feng Y et al, 2012;Sarker S et al, 2021 ). The mangrove wetland ecosystem has a strong interception, adsorption, and xation effects on heavy metals due to its unique habitat characteristics, and thus it often becomes a pollution sink for heavy metal pollutants (Silva C et al, 2006; Kumar A et al, 2016; Soto-Jiménez M F Páez-Osuna F, 2001).…”

“…Heavy metal pollutants have been a research focus for a large number of scholars in the world since the heavy metals have diverse sources, strong resistance to decomposition, long residual time, high toxicity, etc., and may even cause great harm to biological and human health through the food chain or other migration pathways (Nath B et al, 2013;Hu B et al, 2021). Up to now, numerous studies have been conducted on the pollution of heavy metals in mangrove ecosystems in diversi ed regions at home and abroad (Jiang R et al, 2020;Costa-Bddeker S et al, 2020;Shi C et al, 2019). However, previous research areas are principally concentrated in industrial areas and ecological protection areas, few studies have been carried out on heavy metal pollution of mangroves in the urban central business district.…”

Urban mangroves can be used to measure the impact of human activities on the urban ecological environment because mangroves are sensitive to human activities. However, studies on the evaluation of heavy metal elements in urban mangroves are still limited. Consequently, this study selected the urban mangroves in a central commercial area of Zhanjiang Bay as a case study to investigate the content and distribution of the heavy metal elements in mangrove sediments. Combined with the results of elemental analysis, grain size analysis, risk level, influencing factors, and sources of heavy metal pollution in the surficial sediments of the mangroves in the study area were evaluated based on mathematical models and multivariate statistical analysis. The results show that (1) concentration of heavy metals: V> Pb> Cu> Ni> As> Co> Cd> Hg; (2) the content of the eight heavy metal elements has a significant positive correlation with total organic carbon (TOC) and total nitrogen (TN) values, likely as a result of adsorption, complexation, or precipitation of heavy metals by organic matter in the sediments; (3) the mangrove sediments in the study area are affected by heavy metal pollution, among which Cd pollution is the heaviest, followed by Hg pollution; (4) comprehensive analyses of multiple heavy metals using Potential Ecological Risk Index shows that the risk level of the study area is slight to very strong ecological risk; (5) the heavy metals in the study area are mainly derived from human activities such as urban domestic sewage, transportation, and ship pollution.

“…Ranges of anthropogenic pressure in marine ecosystems, including pollution, alteration of flow regime, overfishing, habitat degradation, and invasion of exotic species, are becoming a major problem to the natural ecosystem (Pallottini et al 2015;Ruiz-Compean et al 2017;Boutahar et al 2021). The rapid urbanization of coastal environments and industrialization have caused the degradation of marine ecosystems and the loss of their resources (Jiang et al 2020;Arisekar et al 2021). Deterioration of most marine ecosystems has been linked with trace elements and other pollutants such as organic compounds (Alharbi et al 2019;Almahasheer 2019;Bonanno et al 2020;Jiang et al 2020;Valdelamar-villegas et al 2021).…”

The search for solutions to environmental pollution has been on the increase, with many questions recently as to which marine organisms can bioaccumulate trace elements in the marine ecosystem. Cadmium, Cr, Cu, Fe, Mn, Ni, Pb, and Zn concentrations in sediment, seawater, and seagrass compartments (root, rhizome, and leaf blade) were determined at Rabigh lagoon, Red Sea. This is to provide an insight into the potential of Cymodocea serrulata to bioaccumulate trace elements and as a good candidate to biomonitor these elements in a natural aquatic ecosystem. Results revealed significant variations in trace element concentrations across the three compartments of C. serrulata and the sites, with site S8 located in the most closed part of the lagoon recording the highest concentrations for all the trace elements. The translocation factor (TF rhizome/root = 1.00) of trace elements was higher in the root compartment. This implies that the root compartment is a better bioindicator of trace elements and has more potential to be utilized for biomonitoring. A significant positive correlation (p < 0.01) was established between the trace element concentrations in sediment, seawater, and the three compartments of C. serrulata except for Mn concentration in the compartments. The seagrass C. serrulata can be used for biomonitoring of trace elements in marine ecosystems as our results provide information on its capacity to bioaccumulate these elements. This is one of the key characteristics of a typical bioindicator of aquatic pollutants.
