The integrated biomarker response revisited: optimization to avoid misuse
Provedor de dados: 5
Autores: Devin, S.; Burgeot, Thierry; Giamberini, L.; Minguez, L.; Pain-devin, S.
The growing need to evaluate the quality of aquatic ecosystems led to the development of numerous monitoring tools. Among them, the development of biomarker-based procedures, that combine precocity and relevance, is recommended. However, multi-biomarker approaches are often hard to interpret, and produce results that are not easy to integrate in the environmental policies framework. Integrative index have been developed, and one of the most used is the integrated biomarker response (IBR). However, an analysis of available literature demonstrated that the IBR suffers from a frequent misuse and a bias in its calculation. Then, we propose here a new calculation method based on both a more simple formula and a permutation procedure. Together, these...

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...

A simple approach to integrate the ecotoxicological and chemical data for the establishment of environmental risk levels
Provedor de dados: 52
Autores: Cesar,Augusto; Abessa,Denis Moledo de Souza; Pereira,Camilo Dias Seabra; Santos,Aldo Ramos; Fernández,Nuria; Choueri,Rodrigo Brasil; DelValls,Tomas Angel.
In this work, multivariate and numeric methods were used to integrate the chemical and ecotoxicological data obtained for the sediments from the Santos Estuarine System, and for the vicinity of the discharges of the Submarine Sewage Outfall of Santos, in order to establish more accurately the environmental risks, identify the priority areas and thus provide guidance to control the programs and public policies. For both the datasets, the concentrations which exceeded numeric sediment guidelines tended to be associated to toxicity. For the estuary, this trend was corroborated by the correlations between the toxicity and Cu and PAHs levels, whereas for the sewage outfall region, this was observed through the correlation between the toxicity and Hg contents....
