Soil heavy metal remediation is a key challenge for environmental scientists, with relevant techniques such as phytoremediation, animal remediation, and chemical remediation. Most studies have employed single treatment methods, yielding limited results. The current to find ways enhance the efficiency of soil removal through combined approaches. Therefore, this study compares biological (B: 10 earthworms involving 3 transplanted sunflowers), (C: 1% biochar + 0.25% nZVI), (BC: sunflowers nZVI) in reducing Pb Cd pollution. results indicated that under high concentrations, BC approach facilitated greater accumulation sunflowers, whereas at lower it benefited earthworm accumulation. In approach, exhibited higher peroxidase (POD) activity malondialdehyde (MDA) levels compared B enhancing their tolerance stress. High-throughput sequencing analysis revealed resulted microbial diversity index more complex community structure. This enhances sunflowers' earthworms' physiological metabolic stress, well ability.

Background/Objectives: Petroleum contamination in soil exerts toxic effects on earthworms (Eisenia fetida) through non-polar narcotic mechanisms. However, the specific toxicities of individual petroleum components remain insufficiently understood. Methods: This study investigates four components—saturated hydrocarbons, aromatic resins, and asphaltenes—on artificially contaminated soil, utilizing a combination biochemical biomarker analysis metabolomics to uncover underlying molecular Results: The results revealed that hydrocarbons are most fraction, with EC50 concentrations significantly lower than those other fractions. All tested fractions triggered notable metabolic disturbances immune responses after 7 days exposure, as evidenced by significant changes metabolite abundance within critical pathways such arginine synthesis, a-linolenic acid metabolism, pentose phosphate pathway. According KEGG pathway analysis, saturated hydrocarbon induced marked glycerophospholipid proline metabolism pathways, contributing stabilization protein structure membrane integrity. Aromatic disrupted arachidonic pathway, leading increased myotube production enhanced defense TCA cycle riboflavin were altered during exposure colloidal affecting energy cellular respiration. asphaltene fraction impacted glycolysis, accelerating cycling meet stress-induced increases demands. Conclusions: accounted for highest level toxicity among petroleum-contaminated soils. contributions overall should not be ignored, each uniquely affects key biological functions. These findings emphasize importance monitoring perturbations caused non-target organisms earthworms. They also reveal specificity different

Thallium (Tl), though not essential for biological systems, is widely used in industrial activities, resulting soil pollution and adverse effects on biota. Systematic toxicological studies Tl, especially concerning organisms, are relatively rare. This research evaluates the toxic of Tl earthworms by measuring oxidative stress biomarkers, such as superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST), malondialdehyde (MDA), 8-hydroxydeoxyguanosine (8-OHdG), assessing expression functional genes,
