A Comprehensive Toxicological Assessment of Fulvic Acid

open access: yesEvidence-Based Complementary and Alternative Medicine, 2020
Fulvic acid (FA), a humic substance, has several nutraceutical properties, including anti‐inflammation, antimicrobial, and immune regulation abilities. However, systematic safety assessment remains insufficient. In the present study, a battery of toxicological studies was conducted per internationally accepted standards to investigate the genotoxicity ...

Effect of fulvic acids on lead-induced oxidative stress to metal sensitive Vicia faba L. plant [PDF]

open access: yes, 2012
Lead (Pb) is a ubiquitous environmental pollutant capable to induce various morphological, physiological, and biochemical functions in plants. Only few publications focus on the influence of Pb speciation both on its phytoavailability and phytotoxicity ...

Effect of hydrophilic / hydrophobic fractions of Natural Organic Matter on irreversible fouling of membranes [PDF]

open access: yes, 2009
Natural organic matter (NOM) has been identified as a major factor affecting membrane processes performances, but its impact is difficult to quantify from global parameters such as organic carbon content.

Eu(III)–Fulvic Acid Complexation: Evidence of Fulvic Acid Concentration Dependent Interactions by Time-Resolved Luminescence Spectroscopy [PDF]

open access: yesEnvironmental Science & Technology, 2016
Europium speciation is investigated by time-resolved luminescence spectroscopy (TRLS) in the presence of Suwannee River fulvic acid (SRFA). From complexation isotherms built at different total Eu(III) concentrations, pH values, ionic strength, and SRFA concentrations, it appears that two luminescence behaviors of Eu(III) are occurring.

Impacts of epigeic, anecic and endogeic earthworms on metal and metalloid mobility and availability [PDF]

open access: yes, 2011
The introduction of earthworms into soils contaminated with metals and metalloids has been suggested to aid restoration practices. Eisenia veneta (epigeic), Lumbricus terrestris (anecic) and Allolobophora chlorotica (endogeic) earthworms were ...

Lewis Pair‐Engineered CuMnOx as Cold‐Adapted Multinanozyme for Cooperative Hydrolytic and Oxidative Degradation of Raw Corn Stalk

open access: yesAdvanced Science, EarlyView.
A Lewis pair site design strategy was established to construct Cu‐doped Mn‐based amorphous nanozymes, where Mn and oxygen vacancies generate cooperative acid‐base pairs. The resulting multinanozyme integrates glycosidase‐, oxidase‐, and cold‐adapted enzyme‐mimicking activities, enabling cooperative depolymerization of cellulose and hemicellulose ...

Effects of biologically active substances used in soybean seed treatment on oil, protein and fibre content of harvested seeds

open access: yesPlant, Soil and Environment, 2017
In 4-year trials, soybean seeds were treated with the following biologically active substances: Lignohumate B (a mixture of humic acids and fulvic acids); Lexin (a mixture of humic acids and fulvic acids enriched with auxins); brassinosteroid (a ...
