“…High levels of Na, Pb, Cr, Fe, Mn, Cd, Zn, and Se in the banana may have been attributed to the repeated use and addition of residues as fertilizers in agricultural areas of banana [14]. Besides, studies on banana plants that are grown in industrial areas have elevated levels of Cd, Co, Cu, Fe, Pb, Ni, and Zn [15]. According to Romero-Estévez et al [16], there is no significant health risk to the consumer associated with banana fruits with contamination levels of Cd and Ni, but there is Pb risk for toddlers.…”

The inflorescence of Musa paradisiaca, known as “banana heart” is a structure that includes flowers and bracts of banana, commonly used as food source worldwide. The aims of this study were (1) to determine the mineral components of Musa paradisiaca and (2) to compare the obtained results with previously reported data of Recommendation Dietary Allowances (RDAs) and edible plant permissible limits set by FAO/WHO. The samples were digested using microwave-assisted equipment, while elemental contents were determined by inductively coupled plasma optical emission spectroscopy (ICP OES). Metal (Mg, Ca, Cr, Ni, Cu, Fe, and Zn) and nonmetal (S and P) contents were detected. According to RDA, the inflorescences could be excellent sources of Mg, P, Cr, Cu, Zn, and Fe for females, males, and pregnant women, all age 31–50 y, as well as children (4–8 y). Bracts are good source of Zn for male and pregnant women and good source of Fe for children. All the samples contained considerable amounts of Mg, Ca, P, Ni, Cu, Zn, and Fe, which were quite low to induce deleterious effects (UL). FAO/WHO limits for edible plants have not yet been established for S, P, Mg, and Ca, but Ni and Zn are below of those limit values. However, Cr and Cu concentrations are higher than the values established for edible plants and may pose a threat to human health. Farmers should be encouraged by government agencies, not only for sustainability of production but also to ensure the storage and trade of banana tree inflorescence.

“…After long time practice for banana cultivation, the soil of banana field may have been contaminated by metal(loid)s (Pb, Cr, Fe, Cu, Ni, Mn, Cd, As, and Zn) and are accumulated by different tissues of banana plants (Mohamed et al 2017;Sahodaran and Ray 2018). Besides, studies have shown that banana plants have potential accumulation of trace elements such as Cu, Cd, Co, Fe, Ni, Pb and Zn from soil around the industrial areas (Flores et al 2018). Romero-Estevez et al (2019), specified that increased contents of trace elements especially Cd, As, Ni and Pb pose significant risk to the consumer's health especially children.…”

“…Excess accumulation of trace metal(loid)s in surface soil has destructive impact to the terrestrial ecosystem and thereby poses threats to its inhabitants (Mallick et al 2019). If banana plant is cultivated on trace elements contaminated soil, it may pose significant risks to human health due to ingestion of fruits or other parts of plant (Flores et al 2018). In one hand, continuous banana cultivation in the same land is responsible for trace elements accumulation in soil and nearby plants; and could potentially reduce habitats of soil ecology.…”

Nowadays, there is an emergent public concern about trace elements accumulation in surface soils of banana fields around the industrial area of Bangladesh. This work firstly assessed contamination of metal(loid)s (Cr, Cu, Ni, As, Zn Cd, Mn, Fe, and Pb,) in soils of banana fields, sources and ecological risks of trace elements using various indices, their bioaccumulation in banana plant tissues and probable health risk using chemometric approach. Soils and different tissues of banana (Musa spp.) were collected from long time cultivated banana fields around the industrial area and capital of old Pundranagar, Bangladesh and samples were measured by ICP-MS. Experimental data showed that concentrations range of Cr, Cr, Ni, Cu, As, Cd, Pb, Fe, Mn and Zn in soil were 1.50–61.7, 2.42–87.4, 2.00-100.8, 0.25–31.2, 0.10–12.7, 0.60–91.8, 11330–23782, 8.69–105.9, and 7.50-125.9 mg/kg, respectively. Average level of trace elements in plant parts followed the descending order of roots > leaves > stems > fruits. As a whole, abundances of the examined trace metal(loid)s varied with elements species as well as samples, which occurred apparently due to the variations of parent materials of soil and the excessive use of agrochemicals and pesticides for banana cultivation. Trace elements in soils exhibited moderate to high degree of contamination where Cr, Pb, Zn, Cd and As in soils were mainly originated from anthropogenic activities. Considering health risks of measured metal(loid)s owing to the consumption of banana fruit, both non-cancer and cancer risks were perceived due to As contamination in the study area.

“…The area is advantageous for industry because it is close to Itaguaí Harbor and the Arco Rodoviário Metropolitano (SEMA 1998; Wasserman et al 2013;Silva and Victório 2021). Consequently, the West Zone is subjected to high pollution of substrate, water and air that can be detected in plant organs (Flores et al 2018;Victório et al 2020;Flores et al 2021). The back lling of mangroves to accommodate illegal housing construction has also led to the suppression of ora and fauna of mangroves around Sepetiba Bay, revealing socioenvironmental vulnerability.…”

“…Reports have shown that leaf organ from mangrove areas can adsorb, bioaccumulate or degrade metals and other pollutants using speci c mechanisms (Moreira et al 2011;Flores et al 2018;Victório et al 2020;Victório et al 2021;Flores et al 2021). This work aimed to determine the presence of environmental contaminants in the leaf of R. mangle through microchemical analyses and evaluate morphoanatomical features using microscopy.…”

Rhizophora mangle L. (Rhizophoraceae) is a halophyte from two mangroves in the municipality of Rio de Janeiro in Rio de Janeiro state, Brazil. This work aimed to determine the presence of environmental contaminants in the leaf of R. mangle through morphological and chemical analyses. We collected samples in Coroa Grande mangrove (CG), near an industrial park, and Pedra de Guaratiba mangrove (PG), which is currently under threat of anthropization by domestic occupation. Energy Dispersive X-Ray Spectroscopy (EDS) coupled to Scanning Electron Microscopy (SEM) revealed the presence of chemicals and their relative quantities in leaves. Light microscopy and Scanning Electron Microscopy (SEM) were used to examine leaf tissue. Na, Ca and Cl were found in both CG and PG. Specific leaf area was significantly lower in PG. Leaves from CG also presented the three heavy metals Mn, Zn and Cu. R. mangle presents succulent, hypostomatic leaves with dorsiventral structure. Abundant mucilage and crystals in idioblasts were observed. Slight differences in anatomical qualitative traits between leaves from both sites were detected. Leaves from CG were slightly thicker than those examined from PG, especially on main vein vascular system, and a high quantity of stomata was observed in abaxial surface of leaves from PG. Collectively, these findings indicate that R. mangle is resilient and tolerant to the environmental pollutants and presents functional traits related with saline environments; therefore, the morphoanatomical variations are probably related to abiotic factors.
