Effect of oral exposure to the acaricide pirimicarb, a new varroacide candidate, on apis mellifera feeding rate ArchiMer
Riva, Clemence; Sokolowski, Michel B. C.; Normand, Julien; Santos, Jana Sopkova-de Oliveira; Halm-lemeille, Marie-pierre.
BACKGROUND The ectoparasitic honey bee mite Varroa destructor is one of the main causes related to the gradual decline of honey bees Apis mellifera. Nowadays, beekeepers utilize a wide range of different synthetic acaricides, organic acids and essential oils to keep mite populations under control. A previous work had shown that pirimicarb could be a new varroacide candidate. The aim of this study was to observe the chronic effects on worker honey bees feeding activity after an oral exposure to 1.05 mM of pirimicarb. Long-term effect of a 24 hours exposition to pirimicarb were also tested. RESULTS After three successive trials were performed, no mortality could be detected at the tested concentration, oral exposure to pirimicarb had significant effect on...

Etude d’outils d’évaluation de la contamination ChimiqUe dans les eaux de la ManchE - ECUME ArchiMer
Menet-nedelec, Florence; Halm-lemeille, Marie-pierre; Maheux, Frank; Pierre-duplessix, Olivier; Simon, Benjamin; Gonzalez, Jean-louis; Repecaud, Michel; Facq, Jean-valery.
L’étude ECUME était une opération destinée à tester localement dans les eaux côtières du littoral normand, des outils développés nationalement lors de nombreux travaux, et pressentis pour être utilisés lors des prochaines campagnes d’évaluation de la qualité chimique des masses d’eau littorales pour la DCE.  Ceci afin de déterminer la méthode la plus adaptée et opérationnelle de les déployer, et comparer leurs résultats entre eux et par rapport aux connaissances actuelles des niveaux de contamination. Trois sites ont été choisis : Chausey, baie des Veys et estuaire de Seine. Les résultats des analyses chimiques dans l’eau de mer grâce aux DGT, POCIS, SBSE, et dans les moules ont permis de confirmer le contraste du niveau de contamination en éléments traces...

Joint effects of nine antidepressants on Raphidocelis subcapitata and Skeletonema marinoi : a matter of amine functional groups ArchiMer
Minguez, Laetitia; Bureau, Ronan; Halm-lemeille, Marie-pierre.
Antidepressants are among the most prescribed pharmaceuticals throughout the world. Their presence has already been detected in several aquatic ecosystems worldwide and their effects on non-target organisms justify the growing concern of both the public and regulatory authorities. These emerging pollutants do not occur as isolated compounds but rather as multi-component mixtures, which may lead to increased adverse effects compared to individual compounds. Freshwater and marine algae seem particularly sensitive to pharmaceuticals, including antidepressants. Studies assessing the toxicity of antidepressant mixture to algae focused mainly on binary mixtures of selective serotonin reuptake inhibitors. In the present experiment, the freshwater algae...

Toxicity assessment of five emerging pollutants, alone and in binary or ternary mixtures, towards three aquatic organisms ArchiMer
Di Poi, Carole; Costil, Katherine; Bouchart, Valerie; Halm-lemeille, Marie-pierre.
Despite a growing scientific attention on ecological impact of emerging pollutants (EPs) such as pharmaceuticals, personal care products, and pesticides, knowledge gaps remain regarding mixture toxicity and effects on aquatic organisms. Several EPs were screened in seawater (Normandy, France), and the ecotoxicity of five compounds, chosen on their occurrence in ecosystems and use worldwide, was assessed and were the biocides methylparaben (MP) and triclosan (TCS), a pesticide degradation product (AMPA), and the pharmaceuticals venlafaxine (VEN) and carbamazepine (CBZ). The acute or sub-chronic toxicity, alone or in binary/ternary mixtures of three of them (CBZ, AMPA, and MP), was assessed on one marine and two freshwater organisms: Crassostrea gigas,...
