Comparing Effects of Soil Amendments on Plant Growth and Microbial Activity in Metal-Contaminated Soils

Sustainability, Journal Year: 2025, Volume and Issue: 17(5), P. 2135 - 2135

Published: March 1, 2025

Phytostabilization of metals involves the inactivation in soil through use various materials as amendments, which reduces bioavailability metals, and then introduction vegetation. There are limited data comparing effectiveness different phytostabilization amendments under same environmental conditions. Therefore, aim this research was to compare a range on reducing extractability metal uptake by plants, microbial activity nutrient availability plants. Eight potentially limiting were used pot experiment: two composts (CG, CM), municipal biosolids (SB), bentonite (BEN), phosphorus fertilizer (PF), amorphous iron oxide (FE), waste rock material (WR), calcium carbonate (LM); these compared with typical fertilization (NPK) an untreated control (CTL). The following trace metal-contaminated soils taken from area strong dust fall zinc lead smelter (soil P); outcrop ore-bearing rocks near heap H); artificially polluted spill 1990s S). In general, greatest yields plants (oat white mustard) recorded for compost-treated soils. Changes solubility (Zn) cadmium (Cd) after application largely reflected changes pH. Biosolids caused significant increase extractable Zn Cd, related decrease pH, while reduction Cd observed across both composts, especially compost characterized alkaline Interestingly, low addition another observed, despite pH decrease, pots. This fact proves high sorption capacity towards Cd. microbiological analyses revealed highly beneficial effect dehydrogenases nitrification activities, respiration, whereas amendment respiration

Nano-composites based on Chitin for the Removal of Heavy Metals from Wastewater: A Mini Review

Published: April 28, 2025

Water pollution, mostly due to industrial discharge, is considered be one of the significant challenges globally. There are various industries like leather tanning, electroplating, textile and dyeing units which heavily contribute pollution aquatic system by heavy metals. These metals being non-biodegradable toxic assemble in living beings, leading severe health issues damage environment. Among water treatment mechanisms, adsorption as most effective ways treat waste water, offering advantages such simple design, non-toxicity, cost effectiveness, better efficiency discarding pollutants spite very low concentrations. In thepast, natural polymer based composites for process has gained popularity. this context, chitin-based nanocomposites have shown great potential on account their renewable, biocompatible, eco-friendly traits, making them ideal candidate elimination Chitin, owing its built-in antibacterial properties, functional versatility biodegradability, utilized fabricate that effectively bind metal ions remove it from wastewater. The unique structure chitin, with numerous groups, provides chelation sites facilitate excellent binding ions. This review highlights extraction, properties modification chitin. Further deals development chitinbased adsorbents eradication out contaminated water.

Role of Native Arbuscular Mycorrhizal Fungi in Modulating Nutrient Subcellular Distribution in Wheat Grown in Mn-Toxic Soil

Journal of Xenobiotics, Journal Year: 2025, Volume and Issue: 15(3), P. 70 - 70

Published: May 11, 2025

Heavy metal toxicity leads to impaired crop growth and reduced yields product quality by disrupting plant nutrient uptake, inhibiting development, inducing oxidative stress, causing cellular toxicity. Arbuscular mycorrhizal fungi (AMF) can play a crucial role in crops' adaptation manganese (Mn) regulating uptake altering subcellular compartmentalization. The present study examines the influence of intact extraradical mycelia (ERMs) from native AMF on wheat (Triticum aestivum) grown Mn-toxic soil, with focus tissue-specific Ca, Mg, P, Mn distribution. Wheat cultivated soil pre-colonized using an ERM associated Lolium rigidum or Ornithopus compressus exhibited enhanced improved P contents. During first week growth, concentrations increased wheat's roots shoots, but was subsequently sequestered within cell wall. In contrast, absence ERM, accumulation followed apparent continuous time-course pattern. AMF-mediated wall sequestration seems contribute detoxification limiting excessive cytoplasmic accumulation. Furthermore, AMF-driven changes element distribution suggest dynamic response, wherein early-stage transitions into long-term protective mechanism. These findings highlight potential mitigating stress crops, providing insights for sustainable agriculture remediation strategies.
