Copper uptake by the marine mussel Mytilus edulis in the presence of fulvic acids
Copper uptake and accumulation by the marine mussel Mytilus edulis were studied at different Cu concentrations in chemically defined artificial seawater in the presence and absence of fulvic acids. Both short‐term uptake of Cu by excised mussel gills and Cu accumulation in whole mussels after 24 h of exposure decreased in the presence of fulvic acids compared with their absence at similar ...

Adsorption of humic and fulvic acid on copper surfaces
The presence of natural organic matter (NOM) in drinking water can increase the levels of copper released from copper pipes to water and inhibit the formation of protective deposits such as malachite. Since adsorption of NOM on copper pipes surfaces is believed to be one of mechanisms that explains this phenomenom, the objective of this study was to determine kinetics and the adsorption ...

Priming of prosopis cineraria (L.) druce and acacia tortilis (forssk) seeds with fulvic acid extracted from compost to improve germination and seedlin
Composting of waste plant materials and its use in agriculture and landscape sites is an environmental friendly way of reducing waste material and conserving the environment. In this perspectives a survey has been performed at the Dubai based International Center for Biosaline Agriculture to compost the plants based waste material (lawn cuttings-grass) to compost. The material was inoculated with ...

Humic Acid Factory - Case Study
Humic acids or humus are black or dark brown substances formed by plant or animal residues that are partially or completely decayed. Humus is a substance that facilitates the uptake of fertilizers. Today, the increasing use of chemical fertilizers causes the humus in our land to be rapidly depleted. In order to solve this problem, more and more humic substances (humic acid and fulvic acid) are ...

Development and validation of a chronic Pb bioavailability model for the freshwater rotifer Brachionus calyciflorus
We investigated the univariate effects of Ca, pH and DOC on chronic (48h) Pb toxicity to the freshwater rotifer Brachionus calyciflorus. High pH (8.2) and higher concentrations of DOC were protective against filtered Pb toxicity, whereas Ca was not. However, expressed as free Pb2+ ion, Pb2+ toxicity increased with increasing DOC concentration, indicating that Pb‐Fulvic Acid (FA) complexes may ...

Effects of pH and Ca competition on complexation of cadmium by fulvic acids and by natural organic ligands from a river and a lake
Abstract The technique of competitive ligand-exchange/anodic stripping voltammetry (CLE-SV) was used to investigate effects of pH and Ca concentration on cadmium complexation by fulvic acid (FA), as well as Cd speciation in two different freshwaters, a hardwater Lake Greifen and a softwater River Wyre. Binding of Cd to Suwannee river FA (10 mg/l) was determined at different pH (7–8.5) and in the ...

Fluorescence characteristic changes of dissolved organic matter during municipal solid waste composting
Dissolved organic matter (DOM) of municipal solid waste (MSW) consists of minerals, water, ash and humic substances, and is known to enhance plant growth. In this study, inoculating microbes (ZJ, MS) were used in municipal solid wastes composting, and composting implemented a industrialized technology. During composting, dissolved organic matter was extracted from the compost and purified. The ...

Co-composting of poultry manure with low quantities of carbon-rich materials
To study the feasibility of co-composting poultry manure with low quantities of high-value, carbon-rich materials experiments to characterize three pilot-scale piles were carried out. The piles comprised poultry manure (pile 1), poultry manure and straw (pile 2) and poultry manure and sawdust (pile 3), using wood chips as bulking agent. Pile 1 presented the highest losses of organic matter and ...

Advanced characterization of algogenic organic matter, bacterial organic matter, humic acids and fulvic acids
Advanced characterization techniques of organic matter, including bulk organic characterization, size-exclusion chromatography, three-dimensional excitation–emission matrix, Fourier transform infrared spectroscopy, and fractionations using Amberlite XAD-8/4 resins, were used to investigate differences and similarities in the physicochemical properties of four different organic matter, ...

Application of different organic wastes on soil properties and wheat yield
Fresh and composted organic wastes [beet vinasse (BV), sewage sludge (SS), and a cotton gin crushed compost (CCGC)], were applied for 4 yr to a Typic Xerofluvent in dryland conditions near Seville, Spain. Organic wastes were applied at rates of 5, 7.5, and 10 Mg organic matter ha–1, respectively. The effect on the soil's physical properties, soil microbial biomass, and six soil enzymatic ...

Function and production of carbon based fertilizer
Function of carbon based fertilizer Organic carbon fertilizer based on high-quality humic acid and fulvic acid can promote the formation of soil aggregate structure, reduce soil bulk density, increase cation exchange capacity, and regulate soil pH, thus contributing to improving soil water, fertilizer, heat preservation and ventilation capacity. Carbon based fertilizer processed by fertilizer ...
