“…Differences in root types will also affect the concentration of heavy metals in mangrove tissue (Rezaei et al 2021;Hossain et al 2022). The plank root of X. granatum has the lowest heavy metal concentration compared to the breath root of S. caseolaris and the aerial root of R. apiculata.…”

Abstract. Rozirwan, Khotimah NN, Putri WAE, Fauziyah, Aryawati R, Damiri N, Isnaini, Nugroho RY. 2023. Environmental risk assessment of Pb, Cu, Zn, and Cd concentrations accumulated in selected mangrove roots and surrounding their sediment. Biodiversitas 24: 6733-6742. Mangroves as the largest coastal ecosystem can accumulate heavy metals from their environment. This study aimed to evaluate the environmental risk associated with heavy metal pollution accumulated in the roots of mangroves and the surrounding sediments. The mangrove roots consisted of three species Sonneratia caseolaris, Rhizopora apiculata, and Xylocarpus granatum, collected from three observation stations within the Payung Island mangrove ecosystem in South Sumatra, Indonesia. The concentrations of heavy metals were determined using atomic absorption spectrometry. Statistical analysis employed one-way Analysis of Variance (ANOVA). At the same time, ecological risk assessment utilized the Bioconcentration Factor (BCF), Geoaccumulation Index (Igeo), Contamination factor (Cf), and Pollution Load Index (PLI). The highest sediment concentrations of heavy metals at station 3 were 12.786±0.26 mg/kg for Pb, 10.413±0.011 mg/kg for Cu, 42.752±0.053 mg/kg for Zn, and Cd was not detected. In mangrove roots, the highest concentrations were found in S. caseolaris, with 2.596±0.002 mg/kg for Pb and 11.881±0.015 mg/kg for Zn, while X. granatum exhibited 8.850±0.011 mg/kg for Cu and 0.160±0.020 mg/kg for Cd. BCF values <1 were categorized as exclusion, Igeo<0 indicated non-contamination, Cf<1 signified low pollution, and PLI<0 denoted an unpolluted status. Based on the results, the quality of the mangrove ecosystems affected by heavy metal pollution is currently considered safe regarding environmental risk assessment.

“…The data for BCF, TF and BAF are summarized in Table 6. These factors are usually used to evaluate a plant's ability for phytoremediation (Hossain et al, 2022). BCF refers to the ratio of the element concentration in root to that in soil, it represents the ability of plant root to absorb the element from soil (Siyar et al, 2022).…”

Phytoremediation has been used to remediate contaminated site. This study aims to investigate the potential of the selected native plants to accumulate and tolerate chemical pollutants. Two sites were selected in Southern Tunisia lands (Gabès), i) Gannouch located near the chemical industrial complex and ii) Zerkineis around 35 kilometres far from the industrial activities. Soil and plants were sampled and analysed for cadmium (Cd), lead (Pb), copper (Cu), zinc (Zn) and fluorine (F) concentrations. The native plants were Bassia indica and Chenopodium album, with no obvious morphological toxic symptoms. Results indicated that the upper soil layers were alkaline and salt affected with low organic matter content. The highest levels of fluoride and heavy metal were found in Ghannouch. The contents of Cd, Cu, Pb, Zn and F in the roots, stem and leaves of the native plants exceed the normal ranges and the phytotoxic level. Bioconcentration factor (BCF), translocation factor (TF), and biological accumulation factor (BAF) were determined for each element. Based on these factors the selected plants were classified as excluders, indicators, and accumulators for each element. The native plants, studied herein, seems to have significant potential for phytoremediation, thus they may be used as biomonitors in contaminated soils. Bassia indica identified as Cd, Cu and Pb accumulator, could be an excellent candidate for phytoextraction and phyto stabilization because of its F excluder performance.

“…The research on hyperaccumulators under trace element stress has been extensive. It has been demonstrated by Hossain that plants absorb substances from sediments during phytoextraction and store them in their cells during phytodegradation, during which they convert them into nontoxic ones [34]. Ligustrum lucidum has been found to contain trace elements, such as Pb, Cu, and Zn, which are mainly deposited in the roots and are associated with root-hoarding plants [35].…”

Phytoremediation is becoming more prevalent globally. Literature on phytoremediation strategies in western China is relatively scarce. The present research sought to fill this gap by examining the effects of trace elements such as Cd, Cr, Pb, and Zn on growth, physiological traits, tolerances, and accumulation characteristics in 2-year-old saplings of Ligustrum obtusifolium. The gradient of trace element concentration was determined by adding exogenous trace elements to the soil in a pot experiment: CK (no exogenous trace element), T1, T2, and T3 (Cd 0, 2, 5, and 10 mg/kg; Cr 0, 300, 500, and 700 mg/kg; Pb 0, 400, 800, and 1200 mg/kg; and Zn 0, 300, 500, and 1000 mg/kg, respectively). The results indicated that Chla, Chlb, and total Chls significantly decreased (p < 0.05) in the leaves of L. obtusifolium, with the lowest value obtained during soil treatment with T3. Along with the increase in trace element concentration, the net increase in height, root biomass, aerial biomass, and total biomass was reduced significantly. The net growth of L. obtusifolium under Cr stress did not differ significantly from that of CK at T1; however, the net growth of L. obtusifolium under Cr stress was considerably reduced at T2 and T3. The antioxidant enzyme activity of L. obtusifolium increased under different trace element stresses and first increased and then decreased as trace element levels increased. It was found that the SOD, POD, CAT, and APX activity of L. obtusifolium peaks at T2 under Cd and Zn stress in contrast to a peak at T1 under Cr and Pb stress. The contents of trace elements in L. obtusifolium roots, stems, and leaves increased along with the increase in soil trace element levels. Cr, Pb, and Zn threshold values can be set at 300 mg/kg, 400 mg/kg, and 300 mg/kg, respectively. This is carried out by using a reference index of the biomass of L. obtusifolium decreased by 10%, while the Cd threshold value needs to be further studied. L. obtusifolium would be an appropriate plant for phytoremediation of Cr-polluted soil, compared to Cd, Pb, and Zn absorption and accumulation. It showed optimal antioxidant enzyme activity and transfer ability under soil Cr contents of 300 mg/kg, and the growth of L. obtusifolium was not restricted. Therefore, L. obtusifolium was particularly suitable for phytoremediation of Cr pollution in areas in western China.
