“…With the continuous advancement of urbanization and industrialization, heavy metals are constantly emitted into the terrestrial environment and accumulate in the soil, posing great threats to the quality of soil, groundwater, and crops [ 4 , 5 , 6 ]. Once heavy metals ware in the food chain, the health of humans and other organisms could be affected [ 7 , 8 , 9 , 10 ]. Owing to the potential toxicity and difficult biodegradation of heavy metals, their content in soil has become of great concern [ 9 , 11 , 12 ].…”

The study of threshold levels of heavy metals in soil is essential for the assessment and management of soil environmental quality. This study reviewed the influencing factors, the derivation, and application aspects of heavy metals’ threshold values comprehensively by a combination of bibliometric analysis and scientific knowledge mapping. A total of 1106 related studies were comprehensively extracted from the Web of Science database during the period from 2001 to 2020. The results showed that the publication output has been growing strongly. An analysis on the subject, journal, country, and institution was carried out to demonstrate the development and evolution of this research branch during the two decades. According to high-frequency keywords analysis, external factors (e.g., soil physicochemical properties) and internal factors (e.g., crop genotype) can affect heavy metal threshold values in the soil–crop system. The current methods mainly include the Point model (e.g., evaluation factor method), the Probability model (e.g., species sensitivity distribution method), and the Empirical model (e.g., ecological environment effect method). A threshold study can be applicable to the risk assessment for soil heavy metal contamination in order to determinate the soil pollution degree and its spatial and temporal distribution characteristics. Moreover, challenges and prospects of the study of heavy metal threshold values are proposed, indicating that research should focus on the relationships between human health risks and the established threshold values of heavy metals in the soil, long-term field trials and bioavailability of heavy metals for the derivation of the thresholds, and the establishment of more scientific and rational soil environmental benchmarks.

“…Heavy metal contamination of surface sediments is a major problem faces fast developing towns since sediment quality do not grow along with increase population, industrialization and urbanization. Among environmental contaminants, heavy metals gained special visibility due to the excessive concentrations, non/low-degradability, persistence, bio/ accumulative nature, and harmful effects on living organisms (Fuentes et al 2020, Taati et al 2020). Geological weathering, industrial disposal of metals and metal components, leaching of metals from garbage, solid waste heaps, mining, agriculture, pharmaceutical, domestic e uents, atmospheric sources, unplanned urbanization, haphazard industrialization, animal and human excreta are major sources of heavy metals and rare earth element (Chung 2018).…”

The Pouma area is situated within the Yaoundé domain of the Pan Africa Fold Belt in Cameroon. The rocks in the Pouma area are mainly metamorphic rocks such as quartzite, micaschist and gneiss. The main objective of this study is to evaluate the distribution of trace metals and to assess the degree of metal pollution in the sediments of Pouma area. The sediment samples were analysed for major, trace elements and rare earth elements content byInductively Coupled Plasma-Mass Spectrometer (ICP-MS- Aqua Regia). The calculated pollution load index (1.1 to 8.1), enrichment factor (0.01 to 1221), integrated nemrow pollution load index (3.57 to 25.93) and potential ecological risk index (3 to 7504) of Au, Ag, Al, Ba, Bi, Cd, Co, Cu, Cr, Fe, Hg, Ga, Mo, Nb Ni, Pb, Rb, Sc, Sn, Sr, Th, U, V, Y, Zn and Zr indicate metal pollution and sediments contamination in the Pouma area. Natural and metal input assessment reveals that the dominantly mafic lithologies in the area, mining and domestic activities as well as agricultural activities of Pouma area are the main source of metal contamination.

“…In fact, oceanic habitats are subject to a wide variety of pollutants, among them, heavy metals and trace elements took a significant position 2 . In recent decades, the marine environment shows increasing concentrations of these pollutants following large-scale urbanization, industrialization, and greater agricultural activities 3 , 4 . Heavy metals and metalloids from anthropogenic activities, including mining, milling, petrochemicals processing, electronics industry, and municipal waste, directly discharged into the marine environment or transported into the greater aquatic system via estuaries are of particular concern 5 .…”

Although coastal water marine algae have been popularly used by others as indicators of heavy metal pollution, data within the Bay of Bengal for the estuarine Cox’s Bazar region and Saint Martin’s Island has remained scarce. Using marine algae, the study herein forms an effort in biomonitoring of metal contamination in the aforementioned Bangladesh areas. A total of 10 seaweed species were collected, including edible varieties, analyzed for metal levels through the use of the technique of EDXRF. From greatest to least, measured mean metal concentrations in descending order have been found to be K > Fe > Zr > Br > Sr > Zn > Mn > Rb > Cu > As > Pb > Cr > Co. Potential toxic heavy metals such as Pb, As, and Cr appear at lower concentration values compared to that found for essential mineral elements. However, the presence of Pb in Sargassum oligocystum species has been observed to exceed the maximum international guidance level. Given that some of the algae species are cultivated for human consumption, the non-carcinogenic and carcinogenic indices were calculated, shown to be slightly lower than the maxima recommended by the international organizations. Overall, the present results are consistent with literature data suggesting that heavy metal macroalgae biomonitoring may be species-specific. To the best of our knowledge, this study represents the first comprehensive macroalgae biomonitoring study of metal contamination from the coastal waters of Cox’s Bazar and beyond.
