Les microplastiques en milieu marin : supports de contaminants chimiques - Étude bibliographique
Provedor de dados: 5
Autores: Roclin, Lea.
microplastics are ubiquitous in the marine environment, particularly in ocean gyres. this review makes an assessment of the current knowledge about microplastics as support of chemical contaminants in marine environment. 121 papers were included in this report, with 53 on the theme "microplastics, contaminants and marine environment". adsorption and desorption capacities of contaminants on microplastic depend on the contaminant, the microplastic, and external factors (salinity, organic matter and interaction with other contaminants). regardless of the sampled matrix (water and sand) and the geographical area, results have shown the presence of chemical contaminants on microplastics, which are persistent organic pollutants (pops) in the water (pcbs, pahs,...

Consignes de saisie des données microdéchets flottants dans l'application DALI
Provedor de dados: 5
Autores: Le Moigne, Morgan; Lamoureux, Alice.
L’application DAta LItter a été développée afin de bancariser dans la Base de Données Q², les données liées aux programmes de surveillance mis en œuvre dans le cadre du Descripteur 10 – Déchets marins - de la Directive Cadre Stratégie Marine (D10C1, D10C2, D10C3 et D10C4). Afin d’accompagner la saisie des données, des consignes de saisie sont mises à disposition des utilisateurs. Ce document porte sur les consignes de saisie dans le cadre du Programme de surveillance lié au D10C2 – micro-déchets flottants.

Distribution des microplastiques dans les eaux de sub-surfaces, en Méditerranéenne nord-occidentale
Provedor de dados: 5
Autores: Martinot, Pauline.
Between April and November 2018, 20 microplastic (MPs) samples were collected at 8 sampling stations in French Mediterranean coast from Port-Cros to Banyuls as well as upstream the Rhône River. MPs were found in every sample with variable concentrations, size range and colors. Concentrations ranged from 11 items (Port-Cros) to 15 178 items (Port-Saint-Louis low salinity, PS). The samples with the highest MPs count originate from PS and the Bay of Marseille. MPs count in Spring and Autumn results in 217 (± 12,3) and 351 (± 4,3) respectively for the Bay and particles &gt;1 000 μm dominated sampling stations during both seasons, while PS samples showed greater variability in size distribution. The site PS, near the Rhône River, has the most fiber and the...

Les microplastiques : une menace en rade de Brest ?
Provedor de dados: 5
Autores: Frere, Laura.
World production of plastics has increased steadily for the past decades leading to a major contamination of the worldwide aquatic ecosystems recently estimated at more than five trillion plastic pieces floating the surface of the oceans. Microplastics (plastic particles &lt; 5 mm) are introduced into aquatic environments directly as industrial raw material (plastic pellets, cosmetics, clothing) or indirectly via the fragmentation of larger plastics. This emerging contaminant represents an increasing ecological concern for science and society. The present study focused on the microplastic contamination of the Bay of Brest (Brittany, France), a macrotidal coastal ecosystem characterized by intense anthropogenic activity. The main objectives were: (1) to...

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...
