Determination of soluble ultra-trace metals and metalloids in rainwater and atmospheric deposition fluxes: A 2-year survey and assessment
(Elsevier, 2013)
The present work investigates the relationships between composition of rainwater and dry deposition fluxes by trace metals and metalloids. A modification in automatic “wet-only” and “dry-only” samplers was applied, which ...

Citrate and Polyvinylpyrrolidone Stabilized Silver Nanoparticles as Selective Colorimetric Sensor for Aluminum (III) Ions in Real Water Samples
(MDPI, 2020)
The use of silver nanoparticles stabilized with citrate and polyvinylpyrrolidone as a sensor for aluminum ions determination is proposed in this paper. These non-functionalized and specific nanoparticles provide a highly ...

Volatile organic compounds removal by means of a felt-based living wall to improve indoor air quality
(Elsevier, 2021-03)
Currently, the population spends most of the time in indoor environments, which makes Indoor Air Quality (IAQ) very important for health and comfort. As vegetation can act as a biofilter capturing air pollutants, this ...

A chemical speciation of trace metals for fine urban particles
(Elsevier, 2002)
The chemical speciation of 11 metals in aerosols has been studied in 12 areas of the city of Seville (Spain). Urban particles were collected with a high-volume sampling system equipped with a cascade impactor, which ...

Alginate/geopolymer Hybrid Beads as an Innovative Adsorbent Applied to the Removal of 5-fluorouracil from Contaminated Environmental Water
(Elsevier, 2023)
Water contaminated by cytostatic drugs has many negative impacts on the ecosystems. In this work, cross-linked adsorbent beads based on alginate and a geopolymer (prepared from an illito-kaolinitic clay) were developed for ...

A rapid Soxhlet and mini-SPE method for analysis of polycyclic aromatic hydrocarbons in atmospheric particles
(Springer, 2021-02-16)
An analytical method was validated with two reference materials of polycyclic aromatic hydrocarbons in atmospheric particles. Standard reference materials (SRMs) were incorporated into the matrix of unexposed cut quartz ...

An Overview of Analytical Methods to Determine Pharmaceutical Active Compounds in Aquatic Organisms
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
There is increasing scientific evidence that some pharmaceuticals are present in the marine ecosystems at concentrations that may cause adverse effects on the organisms that inhabit them. At present, there is still very ...

Physical speciation of arsenic, mercury, lead, cadmium and nickel in inhalable atmospheric particles
(Elsevier, 2004)
Physical speciation of metals (size distribution) in airborne particles has been studied in 24 areas of Seville (Spain). Urban particles were collected with a high-volume sampling systems equipped with cascade impactor and ...

Assessment of in vitro bioaccessibility of carotenoids and phenolic compounds in a model milk-mandarine beverage
(Royal Society of Chemistry, 2022-09-20)
Mandarine juice is one of the richest sources of β-cryptoxanthin and flavonoids, which have been positively associated with bone mineral density. Carotenoids are lipophilic isoprenoid compounds with a complex absorption ...
