Improving the mining soil quality for a vegetation cover after addition of sewage sludges: Inorganic ions and low-molecular-weight organic acids in the soil solution
(Elsevier, 2015-03-01)
We assessed the effects of applying stabilized sewage sludge (SSL) and composted sewage sludge (CLV), at 5 and 10% to an acid mining soil. Limed soil (NCL) amended or not with SSL and CLV was incubated for 47 days. We ...

Chemical speciation of trace metals in fine airborne particles: advances in operational performance of a new sequential extraction scheme
(Taylor & Francis, 2006)
A speciation method of inorganic metal compounds in airborne particulate matter based on selective sequential extractions is described. The sequential leaching procedure was perfected for improvement of performance at ...

Contribution of specific volatile markers to green and ripe fruity attributes in extra virgin olive oils studied with three analytical methods
(Elsevier, 2022)
An objective sensory evaluation of extra virgin olive oil (EVOO), involving the chemical characterization of positive attributes, is of interest. These attributes are objectively divided, according to fruitiness, into ...

Optimization of a Sequential Extraction Scheme for Speciation of Metals in Fine Urban Particles
(Taylor & Francis, 2002)
A sequential extraction procedure fractioned in four steps was optimized with the purpose of improving a previous scheme for determining the chemical forms of metals in fine airborne particles. The optimization was tested ...

Study of PM2.5-bound Polycyclic Aromatic Hydrocarbons and Anhydro-sugars in Ambient Air Near Two Spanish Oil Refineries: Covid-19 Effects
(Elsevier, 2023)
We report the results from a 12 month-long study of the organic compounds associated to PM2.5 samples collected around two petroleum refineries (4 samples/month/site) in two complex industrial zones reporting atmospheric ...

Impact of “chemical cocktails” exposure in shaping mice gut microbiota and the role of selenium supplementation combining metallomics, metabolomics, and metataxonomics
(Elsevier, 2022)
Biological systems are exposed to a complex environment in which pollutants can interact through synergistic or antagonistic mechanisms, but limited information is available on the combined effects. To this end, conventional ...

Potential Release and Bioaccessibility of Metal/loids from Mine Wastes Deposited in Historical Abandoned Sulfide Mines
(Elsevier, 2023)
This study deals with the potential release of metal/loids from sulfide mine wastes upon weathering and the health risks associated with their accidental ingestion. To address this, a complete chemical and mineralogical ...

Atmospheric emissions of volatile organic compounds from a mine soil treated with sewage sludge and tomato plants (Lycopersicum esculentum l.)
(Springer Science and Business Media, 2022-07-06)
The study investigated the emissions of volatile organic compounds (VOCs) from a mining soil amended with sewage sludge and irrigated with wastewater with or without tomato plants. The aim is to find out whether amendment ...

Impact of adding white pomace to red grapes on the phenolic composition and color stability of syrah wines from a warm climate
(American Chemical Society, 2014-03-26)
The influence of the fermentative addition of Pedro Ximenez grape pomace (PXGP, white variety) on the phenolic composition and color of Syrah red wines from a warm climate was studied. Changes on phenolic composition (HPLC), ...
