Contamination des milieux aquatiques par les substances pharmaceutiques et cosmétiques - Etat des lieux et perspectives
Provedor de dados: 5
Autores: Collette-bregand, Maude; James, Alice; Munshy, Catherine; Bocquene, Gilles.
This document reports a survey of the aquatic contamination by cosmetics and medicinal products for human and veterinary uses. The contamination of the continental, estuary and coastal waters by these substances gives rise to questions on environmental risk assessment and management. Among the pharmaceutical classes involved, substances such as anti-inflammatory drugs, steroid hormones, antibiotics and hypolipemiants are of particular concern. Present regulations do not take into account the medical effluents in the environment. A significant part of these substances is not destroyed in water treatment plants whereas veterinary substances are directly spread in the environment. Some molecules occur in particularly high concentrations as shown for...

Occurrence of phthalate acid esters (PAEs) in the northwestern Mediterranean Sea and the Rhone River
Provedor de dados: 5
Autores: Paluselli, Andrea; Aminot, Yann; Galgani, Francois; Net, Sopheak; Sempere, Richard.
Phthalate acid esters (PAEs) which are mainly anthropogenic molecules with endocrine disrupting effects in animals and humans, have been detected in terrestrial and aquatic environments. However, little is known about their distribution in the Mediterranean Sea, mainly because of analytical difficulties and the high possibility of ambient sample contamination. Here, we report the optimization of an existing protocol for the determination of PAEs in seawater and freshwater samples, as well as the first estimation of the source and distribution of phthalates acid esters (PAEs) in coastal waters from the NW Mediterranean Sea. By passing 1 L of sample through glass cartridges packed with 200 mg of Oasis HLB and eluted with 6 mL of ethyl acetate, the recoveries...

Autores: Paluselli, Andrea; Fauvelle, Vincent; Schmidt, Natascha; Galgani, Francois; Net, Sopheak; Sempere, Richard.
Phthalic Acid Esters (PAEs) are a group of emerging organic contaminants that have become a serious issue because of their ubiquitous presence and hazardous impact on the marine environment worldwide. Seawater samples were collected monthly from December 2013 to November 2014 in the northwestern Mediterranean Sea (Marseille Bay). The samples were analyzed for dissolved organic carbon (DOC) as well as the molecular distribution of dissolved PAEs by using solid phase extraction followed by gas chromatography and mass spectrometry (GC/MS) analyses. The results demonstrated the occurrence of six PAEs, including dimethyl phthalate (DMP), diethyl phthalate (DEP), di-isobutyl phthalate (DiBP), di-n-butyl phthalate (DnBP), benzylbutyl phthalate (BzBP) and...

Analyse, distribution, production et dégradation d’esters de phtalates (PAEs) en zone côtière méditerranéenne
Provedor de dados: 5
Autores: Paluselli, Andrea.
Phthalic Acid Esters (PAEs) are a group of emerging organic contaminants that have become a serious issue because of their ubiquitous presence on the marine environment worldwide and for the endocrine disrupting effects in animals and humans. However, little is known about their distribution in the Ocean, mainly because of analytical difficulties and the high possibility of ambient sample contamination. Plastic debris in marine environment includes resin pellets, macro- and microplastic fragments, and contains additives such as PAEs that might be released in the aquatic environment in unknown proportion. In our work, we improved an analytical method for the determination of 8 PAEs, at trace levels in marine and fresh waters. In the first part of the...

Removal of synthetic sex hormones by hydrothermal carbonization
Provedor de dados: 42
Autores: MORAIS,RUITER L.; SANTIAGO,MARIÂNGELA F.; ZANG,JOACHIM W.; FONSECA-ZANG,WARDE A.; SCHIMIDT,FERNANDO.
ABSTRACT One of the most prominent fields of environmental chemistry is the study and the removal of micro-pollutants from aqueous matrices. Analytical techniques for their identification and quantification are becoming more sensitive and comprehensive and, as a result, an increasing number of drugs have been detected in environmental samples. However, the literature shows that conventional treatments for drinking water and wastewater are not sufficient for remove these compounds. This study aims to check whether the process of hydrothermal carbonization (CHT) is effective in removing the synthetic sex hormones: ethinyl estradiol, gestodene and cyproterone acetate from aqueous samples. The system used in CHT basically consists of a pressurized reactor made...
