Removal of priority and emerging pollutants from aqueous media by adsorption onto synthetic organo-funtionalized high-charge swelling micas
(Elsevier, 2018-07)
In this work, the removal of different types of emerging pollutants (four perfluoroalkyl compounds, two preservatives, three surfactants and nine pharmaceutical compounds) from aqueous solution by adsorption onto two novel ...

Biomonitoring of 21 endocrine disrupting chemicals in human hair samples using ultra-high performance liquid chromatography-tandem mass spectrometry
(Elsevier, 2017-02)
Rapid industrial growth has increased human exposure to a large variety of chemicals with adverse health effects. These industrial chemicals are usually present in the environment, foods, beverages, clothes and personal ...

Multi-residue analysis of 36 priority and emerging pollutants in marine echinoderms (Holothuria tubulosa) and marine sediments by solid-liquid extraction followed by dispersive solid phase extraction and liquid chromatography–tandem mass spectrometry analysis
(Elsevier, 2017-05)
Marine echinoderms are filter-feeding invertebrates widely distributed along the coasts, and which are therefore extensively exposed to anthropogenic xenobiotics. They can serve as good sentinels for monitoring a large ...

François-Antoine-Henri Descroizilles (1781-1825), démonstrateur royal de chimie, apothecary, inventor and industrial chemist: the father of titrimetric analysis. Part II
(Real Academia Nacional de Farmacia, 2018)
In the first part of this contribution, the boundary conditions of the new bleaching method proposed by Berthollet after the discovery of chlorine (oxygenated muriatic acid) by Scheele have been addressed. This second ...

Validated method for the determination of perfluorinated compounds in placental tissue samples based on a simple extraction procedure followed by ultra-high performance liquid chromatography tandem mass spectrometry analysis
(Elsevier, 2016-04)
Xenobiotic exposure during pregnancy is inevitable. Determination of perfluorinated compounds (PFCs), chemicals described as environmental contaminants by Public Health Authorities due to their persistence, bioaccumulation ...

Bioaccumulation of perfluoroalkyl substances in marine echinoderms: Results of laboratory-scale experiments with Holothuria tubulosa Gmelin, 1791
(Elsevier, 2019-01)
Bioaccumulation of six perfluoroalkyl substances (PFAS) was assessed using the marine echinoderm Holothuria tubulosa Gmelin, 1791. Batch experiments were conducted to establish the relationship between concentrations in ...

Evaluation of a modified mica and montmorillonite for the adsorption of ibuprofen from aqueous media
(Elsevier, 2019-04)
The goals of this work were to prepare and characterize two functional materials, a natural montmorillonite (Mt) and a synthetic mica (Na-mica-4) were modified with the cationic octadecylamine by a cation-exchange reaction ...

Assessing bioaccumulation potential of personal care, household and industrial products in a marine echinoderm (Holothuria tubulosa)
(Elsevier, 2020-06)
A bioaccumulation study of 16 emerging contaminants including preservatives, UV-filters, biocides, alkylphenols, anionic surfactants and plasticizers, in Holothuria tubulosa Gmelin, 1791 specimens was developed. Water and ...

Adsorption of propranolol onto montmorillonite: Kinetic, isotherm and pH studies
(Elsevier, 2019-06)
The objective of this study was to explore the potential use of the smectite clay mineral montmorillonite (Mt) as adsorbent in the removal of water containing the emerging compound propranolol. The Mt was deeply characterized ...

Exposure assessment to parabens, bisphenol A and perfluoroalkyl compounds in children, women and men by hair analysis
(Elsevier, 2019-12)
Population is continuously exposed to endocrine disrupting compounds present in everyday products such as parabens, bisphenol A (BPA), and perfluoroalkyl compounds (PFCs). The aims of this study were, first, to evaluate ...
