“…The concentration of heavy metals (Pb) in the roots showed a high concentration due to the influence of the finer sediment size which causes a higher accumulation of heavy metals. Pb in the sediment varied with different seasons, ranging from Pb (0.43-17.49) mg/kg [27]. 1 shows the Pb contents in various parts of the R. apiculata mangrove.…”

Mangroves have an ability in environmental conditions, i.e., in the sediment, and organs. This research was carried out to assess the Pb absorption rate (sediment and mangrove parts of R. apiculata) in the eastern coast of Asahan, North Sumatra. The results showed that Pb content increased in the sediment, but it significantly decreased in leaves. The highest Pb content was in the sediment > roots > fruits > stem bark > leaves. The PCA results of factor loading showed that in the sediment (0.98), roots (0.98), fruits (0.98), stem bark (0.74) and leaves (0.98). The bioaccumulation factor (BAF) and translocation factor (TF) were < 1 indicating that R. apiculata has a capability of heavy metal absorption, especially Pb. Pb had a positive correlation in the sediment and roots.

“…Maximum concentrations of Cd exceeding the threshold for toxic effects indicate a hazardous risk to organisms in the sediment. Ganeshkumar et al, (2019) also reported on the existence of different seasonal variations of heavy metal concentrations in plant tissue ranging from 0.10 to 0.62 (Cd) mg/kg.…”

Mangroves of R. apiculata and A. marina have the ability and capability to absorb or bioaccumulate heavy metals. The purpose of this study was to determine and compare bioaccumulation of heavy metal Cd in A. marina and R. apiculata in the sediment and mangrove organ tissues. This research was conducted from March to August 2020 in the East Coast of Sumatra, Asahan Regency. Data analysis was carried out at the Aquaculture Study Program, Asahan University. The statistical analysis was performed using Principal Component Analysis (PCA) to examine the relationships and comparisons. The results showed that the Cd content in the mangrove sediment of A. marina was 0.05 ± 0 mg/kg) and R. apiculata was 0.03 ± 0 mg/kg.

“…For example, young mangrove trees of R. apiculata bioextracted chromium (Richter et al 2016). Meanwhile, R. mucronata is considered a bioindicator by its good accumulation and translocation rate of Pb (Ganeshkumar et al 2019). Rhizophora mangle is also considered an important bioindicator of mangrove areas contaminated by various metals based on atomic absorption spectrophotometry analysis (Pinheiro et al 2012).…”

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. Speci c leaf area was signi cantly 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 ndings 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. Highlights-The main minerals detected by EDS were Na, Ca and Cl.-Zn and Cu were the only heavy metals detected in R. mangle leaves in samples from CG.-A large number of stomata in leaves were observed in plants from PG.-Differences in spongy parenchyma and stomata were noted between leaves of PG and CG.-No anatomical changes related to pollution were noted.
