TL;DR: The network correlation pattern confirmed that the relative greater percentage of correlation among dominant HMRF community with bio-available HM and other physicochemical factors increased with the addition of biochar, suggesting that the biochar amendment in composting could constitute favorable habitat for an active fungal population.
Journal ArticleDOI
Critical passivation mechanisms on heavy metals during aerobic composting with different grain-size zeolite.
TL;DR: Redundancy analysis (RDA) and structural equation models (SEMs) indicated that zeolite accelerated the passivation effect on Cd and Pb through regulating the electrical conductivity (EC) as a result of surface adsorption, and on Cu by influencing total carbon (TC) under the function of humification.
Journal ArticleDOI
Review on fate and bioavailability of heavy metals during anaerobic digestion and composting of animal manure.
TL;DR: In this article , the authors systematically summarized the migration of heavy metals and the transformation of several typical heavy metals (Cu, Zn, Cd, As, and Pb) during anaerobic digestion and composting.

Biochar - An effective additive for improving quality and reducing ecological risk of compost: A global meta-analysis.
TL;DR: In this paper, the authors conducted a global meta-analysis based on 876 observations from 84 studies and found that biochar addition could significantly increase the pH (5.90%), germination index (26.6%), contents of nitrate nitrogen (56.6), total nitrogen (9.50%), and total potassium (10.4%), while decrease the electrical conductivity (−5.70%), bioavailable zinc (−22.9%), and bioavailable copper (−38.6%).

Journal ArticleDOI
Fluorescence excitation-emission matrix regional integration to quantify spectra for dissolved organic matter.
TL;DR: Aromatic carbon and the presence of specific aromatic compounds resulted in EEMs that aided in differentiating wastewater effluent DOM from drinking water DOM, and the highest cumulative EEM volume was observed for hydrophobic neutral DOM fractions.

Biochar for environmental management: an introduction
Johannes Lehmann,Stephen Joseph +1 more
TL;DR: Biochar is the product of heating biomass in the absence of or with limited air to above 250oC, a process called charring or pyrolysis also used for making charcoal as discussed by the authors.

Maturity and stability parameters of composts prepared with a wide range of organic wastes
TL;DR: In this paper, seven different composts were prepared by the Rutgers static-pile system using a wide range of wastes: sewage sludge, poultry manure, pig slurry, olive mill wastewater city refuse and the lignocellulosic wastes cotton waste, maize straw and sweet sorghum bagasse.

Antibiotic uptake by plants from soil fertilized with animal manure.
TL;DR: The potential human health risks associated with consumption of fresh vegetables grown in soil amended with antibiotic laden manures may be higher for people who are allergic to antibiotics and there is also the possibility of enhanced antimicrobial resistance as a result of human consumption of these vegetables.

Fate of lignins in soils: A review
TL;DR: In this paper, the authors synthesize the current knowledge and recent progress about quantity, composition and turnover of lignins in soils and identify variables determining lignin residence time.
