Different transfer pathways of an organochlorine pesticide across marine tropical food webs assessed with stable isotope analysis.
PloS one, 2018Co-Authors: Charlotte R. Dromard, Yolande Bouchon-navaro, Sébastien Cordonnier, Mathilde Guéné, Mireille Harmelin-vivien, Claude BouchonAbstract:Chlordecone is a persistent organochlorine pesticide used in the banana fields of the French West Indies from 1972 to 1993. Three marine habitats (mangroves, seagrass beds and coral reefs) of two study sites located downstream contaminated rivers were chosen to evaluate the level of contamination of marine food webs. On each habitat, the food chain collected included suspended organic matter, primary producers (macroalgae, algal turf, seagrass), zooplankton, symbiotic organisms (corals, sea anemones), primary consumers (herbivores, suspension feeders, biofilm feeders), omnivores and detritivores (lobsters, fish), secondary consumers (carnivores 1: invertebrate feeders, planktivores) and tertiary consumers (carnivores 2: invertebrate and fish feeders, piscivores). Log-linear regressions of the concentrations of chlordecone versus nitrogen isotopic ratios (δ 15 N) were used to assess the bioaccumulation of chlordecone along trophic food webs. At each site, biocon-centration and bioamplification take part on the transfer of chlordecone in marine organisms. In mangroves (i.e. close to the Source of Pollution), lower trophic magnification factors (TMF) indicated that bioconcentration prevailed over bioamplification phenomenon. The opposite phenomenon appeared on coral reefs in which bioconcentration processes were less important and bioamplification pathway became dominant. Far from the Source of Pollution , molecules of chlordecone seemed to be transfered to organisms mostly via trophic interactions rather than water contact.

efficiency of storm detention tanks for urban drainage systems under climate variability
Journal of Water Resources Planning and Management, 2012Co-Authors: Ignacio Andresdomenech, Alberto Montanari, J B MarcoAbstract:Climate change effects on combined sewer systems efficiency is a great matter of concern. In fact, changes in rainfall regime could significantly affect combined sewer overflows (CSOs) into receiving water bodies. Given that CSOs are a significant Source of Pollution, a better understanding and modeling of climate change effects on urban drainage systems is a compelling requirement to support design of adaptation strategies. This paper aims at studying the resilience of storm water detention tanks efficiency with respect to changes in rainfall forcing. In detail, an analytical probabilistic model is proposed to assess overflow reduction efficiency and volumetric efficiency of detention tanks depending on behaviors of climate and urban catchment. Sensitivity of tank efficiencies is evaluated under assigned changes in rainfall forcing. Results show that resilience of storm tanks benefits from filtering of climate change effects operated by the urban catchment.
