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

Phytotoxicity and Metals Mobility Assessment in Mining Wastes Amended with Various Biochars

Land, Journal Year: 2025, Volume and Issue: 14(2), P. 372 - 372

Published: Feb. 11, 2025

Mining activities often contaminate soils with heavy metals, generating environmental and health risks. This study investigates the ecotoxicity of muddy (Mw) sandy (Sw) mining wastes on Phaseolus vulgaris assesses impact five locally sourced biochar amendments plant growth soil pore water (SPW) properties. Most biochars improved retention, except for argan nut shells (An) biochar, highlighting importance feedstock type. Sw supported better than Mw regardless addition, due to textural differences. Palm fronds (Pf) significantly enhanced surface leaf area in Sw. SPW analysis revealed that affected pH electrical conductivity (EC) differently across types. consistently increased pH, while Sw’s was biochar-dependent. A significant 5.1-fold EC increase recorded amended Pf. All reduced Pb availability at planting, Cu decreased harvest. In Mw, Pb, Zn, Cu, uptake accumulation were unaffected by a slight reduction observed roots. germination test Lepidium sativum confirmed these findings, particularly inhibition An. dual approach highlights toxicity biochars’ potential as remediation programs.

Heavy metals (HMs) or/and polycyclic aromatic hydrocarbons (PAHs) stress have significant adverse effects on the photosynthetic function and SPAD values of plants. Physiological integration is typical feature clonal plants, which can mitigate ramets under heterogeneous stress. However, sustainability physiological between clones over prolonged durations, dynamics intensity potential differences various types remain unclear. This study examined three different stresses—cadmium (Cd), phenanthrene (Phe), a combination Cd Phe (Cd + Phe) Zoysia japonica at time points. The results indicate that significantly enhances value, net rate (PN), stomatal conductance (Cond), intercellular CO₂ concentration (Ci), transpiration (Tr), water use efficiency (WUE). diminishes with exposure. In addition, among types, initial was highest toxicity conditions, it decreased most rapidly, resulting in lowest during later stages To sum up, this highlights role maintaining plants elucidates temporal changes conditions.
