Reduced adsorption of caesium on clay minerals caused by various humic substances [PDF]

open access: yes, 1999
The effect of the addition of various humic substances on the adsorption of caesium on two mineral clays has been studied. All measurements were carried out in dilute suspension under controlled conditions of temperature and ionic strength.

Facilitated Transport of Organic Contaminants in a High Concentration, Multicomponent Plume

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract A field experiment evaluated the transport of organic contaminants in a plume from hazardous waste disposal areas at the Rocky Mountain Arsenal. The plume contained many xenobiotic contaminants, with widely varying expected mobilities.

Acid-base Properties of Modified Peat Fulvic Acid

open access: yesProcedia Chemistry, 2014
AbstractThe Effect of Mechanochemical modification on the acid-base properties of fulvic acid peat has been studied. It is found that modifying reagent CS(NH2)2 increases the amount of aromatic fragments and has no effect on the depletion of functional groups.

Joint effects of elevated copper and temperature in juvenile Tambaqui exposed in black and white waters of the Amazon

open access: yesJournal of Fish Biology, EarlyView.
Abstract This study aimed to investigate how exposure to elevated water temperature and metal concentration jointly affect the physiology of Amazonian fish. Aboard a research vessel in the Amazon, we evaluated the effects of water temperature (river T°C at 31.5°C and a + 4°C increase to 35.5°C) and of 3‐h copper (Cu) exposure (up to 600 μg/L) in ...

Effects of growth stage and fulvic acid on the diversity and dynamics of endophytic bacterial community in Stevia rebaudiana Bertoni leaves

open access: yesFrontiers in Microbiology, 2015
The aim of this study was to learn the interactions among the endophytic bacteria, the plant growth, the foliar spray of fulvic acid, and the accumulation of steviol glycosides in the leaves of Stevia rebaudiana.

3‐Methyl‐1‐Butanol Enhances Postharvest Resistance of Red Grapes to Botrytis cinerea by Activating Phenylpropanoid Metabolism and Antioxidant Defences

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Grey mould, caused by Botrytis cinerea, is a significant postharvest disease leading to substantial economic losses in the grape industry. This study investigated the regulatory mechanism of 3‐methyl‐1‐butanol (3M1B), a yeast volatile substance, on B. cinerea resistance in red grapes (Vitis vinifera L.).

Bacillus velezensis 83 protects Arabidopsis thaliana against Botrytis cinerea by triggering JA‐, and SA‐dependent induced systemic resistance

open access: yesPest Management Science, Volume 82, Issue 3, Page 2532-2540, March 2026.
B. velezensis 83 protects the plant against B. cinerea, accumulating acetoin and activating jasmonic acid‐ and salicylic acid‐mediated defense responses. Abstract BACKGROUND Modern agriculture is based on the application of synthetic agrochemicals to control multiple abiotic and biotic stresses.

Long-term fate of sewage-sludge derived cadmium in arable soils [PDF]

open access: yes, 2003
The focus of this work was to improve knowledge of the long-term fate of cadmium supplied to arable soils by sewage sludge. Emphasis was placed on measured and modelled changes in the solubility and mobility of cadmium, resulting from long-term turnover ...

Mercury speciation, transformation, and transportation in soils, atmospheric flux, and implications for risk management : a critical review [PDF]

open access: yes, 2019
Mercury (Hg) is a potentially harmful trace element in the environment and one of the World Health Organization's foremost chemicals of concern. The threat posed by Hg contaminated soils to humans is pervasive, with an estimated 86 Gg of anthropogenic Hg

Ozonated irrigation in vineyards: limited effects on soil bacterial and fungal microbiota

open access: yesPest Management Science, Volume 82, Issue 3, Page 2746-2757, March 2026.
Irrigation with ozonated water caused slight changes in bacterial composition but did not significantly affect microbial diversity, beneficial microbes (plant growth‐promoting bacteria, arbuscular mycorrhizal fungi), or grapevine trunk disease‐related pathogens.
