Invivo and Invitro neurochemical-based assessments of wastewater effluents from the Maumee River area of concern( )

1 edition published in 2016 in English and held by 1 WorldCat member library worldwide

Abstract: Wastewater treatment plant (WWTP) effluents contain potentially neuroactive chemicals though few methods are available to screen for the presence of such agents. Here, two parallel approaches (invivo and invitro) were used to assess WWTP exposure-related changes to neurochemistry. First, fathead minnows (FHM, Pimephales promelas) were caged for four days along a WWTP discharge zone into the Maumee River (Ohio, USA). Grab water samples were collected and extracts obtained for the detection of alkylphenols, bisphenol A (BPA) and steroid hormones. Second, the extracts were then used as a source of invitro exposure to brain tissues from FHM and four additional species relevant to the Great Lakes ecosystem (rainbow trout (RT), river otter (RO), bald eagle (BE) and human (HU)). The ability of the wastewater (invivo) or extracts (invitro) to interact with enzymes (monoamine oxidase (MAO) and glutamine synthetase (GS)) and receptors (dopamine (D2) and N-methyl-d -aspartate receptor (NMDA)) involved in dopamine and glutamate-dependent neurotransmission were examined on brain homogenates. Invivo exposure of FHM led to significant decreases of NMDA receptor binding in females (24-42%), and increases of MAO activity in males (2.8- to 3.2-fold). Invitro, alkylphenol-targeted extracts significantly inhibited D2 (66% in FHM) and NMDA (24-54% in HU and RT) receptor binding, and induced MAO activity in RT, RO, and BE brains. Steroid hormone-targeted extracts inhibited GS activity in all species except FHM. BPA-targeted extracts caused a MAO inhibition in FHM, RT and BE brains. Using both invivo and invitro approaches, this study shows that WWTP effluents contain agents that can interact with neurochemicals important in reproduction and other neurological functions. Additional work is needed to better resolve invitro to invivo extrapolations (IVIVE) as well as cross-species differences. Highlights: We conducted invivo and invitro neurochemical-based assessments of WWTP effluents. Fish were exposed invivo, brain samples (birds, mammals, fish) were dosed invitro . Invivo exposure led to a decrease of NMDA binding and an increase of MAO activity. Invitro, alkylphenol-targeted extracts significantly inhibited D2 and NMDA binding. MAO was induced by alkylphenol extracts and inhibited by BPA extracts in some species. Abstract : Invivo and invitro approaches showed that WWTP effluents contain agents that can interact with neurochemicals important in reproduction and behavioural functions in various species
Décontamination métallique et capacités de récupération de deux composantes biologiques d'un hydrosystème naturel (biofilms diatomiques et bivalves filtreurs) après remédiation d'un site industriel by Adeline Arini( )

1 edition published in 2011 in French and held by 1 WorldCat member library worldwide

Located in France, in Aveyron, the mining basin of Viviez was submitted for over a century to metal discharges (mainly Cd and Zn) and was proven in the 1970s to be the source of the contamination of the Gironde estuary. In this context, significant soil remediation works were initiated in 2007. The main objectives of this thesis focused on the characterization of the first impacts of remediation on the chemical and ecological improvement status of the hydrosystem via the study of periphytic biofilms and filter-feeding bivalves Corbicula fluminea. In anticipation of the long-term effects of the remediation, a second part was devoted to evaluate the decontamination capabilities of the two biological models and to focus on the restructuring capacities of diatomcommunities in response to metal stress by translocations in situ or to laboratory. Monitoring of metal bioaccumulation carried out in situ between 2008 and 2010 revealed the persistence of a strong gradient of contamination, causing major shifts in the diatom communities of biofilms. In addition, an increase in metal contamination pressure was measured down streams the industrial site in 2010, certainly in relation with the excavation works. Decontamination studies were conducted in the laboratory after in situ exposure of organisms during two seasons. Corbicula fluminea showed fast depuration of Zn, while 15 months were not long enough to get the total decontamination of Cd, estimated complete after 740 to 1360 days according to the exposure season. Although the potential for metal decontamination of biofilms appeared to be rapid under natural conditions after transplantation, laboratory studies conducted over several weeks in artificial streams did not result in complete decontamination of Cd after 100 days, and was estimated complete after 150 to 450 days according to the exposure season. Despite the beginnings of restructuration, no return to communities similar to controls could be observed. These studies have emphasized the importance of the phenomena of species migration in the recoverypotential of biofilms. Finally, a study focussing on diatom teratologies revealed their long persistence in the population despite the stop of the contamination. All these studies demonstrated the complementary usefulness of both biological models, which differently integrate and regulate contaminants, to assess their recovery potential in a remediation context of the hydrosystem
