“…Oligochaeta (Annelida: Clitellata) are recognized as highly diverse groups inhabiting a wide variety of aquatic ecological habitats. Due to their sensitivity to pollution (Rodriguez and Reynoldson, 2011;Tixier et al, 2011), these groups are used as a valuable tool in biomonitoring programs for water quality (Prygiel et al, 2000;Lafont et al, 2012;Vivien et al, 2014). These organisms can be found living on sandy and clay substrates, or in environments enriched by organic matter (Dornfeld et al, 2006).…”

“…Etablis à partir de données nord-américaines, ils n'ont cependant été que partiellement validés en France [Babut, M. et al 2004]. Vivien et al (2014), qui confrontent des données de contamination des sédiments de 35 sites par des métaux, PCB et HAP dans le bassin Artois-Picardie aux valeurs de l'indice IOBS (oligochètes) confirment de leur côté la capacité prédictive des TEC et PEC, et proposent une valeur seuil égale à 0,17 pour l'indice HQ PEC .…”

Vers une démarche graduée d'évaluation écotoxicologique des sédiments fluviaux : présentation et premiers tests

Composante essentielle des écosystèmes fluviaux, les sédiments constituent aussi souvent une source de perturbations des ouvrages tels que barrages ou écluses. Pour gérer ces perturbations sans entrainer de dommages à l'environnement, les maitres d'ouvrage concernés doivent donc disposer d'une démarche d'évaluation écotoxicologique. Le projet DIESE (Outils de DIagnostic de l'Ecotoxicité des SEdiments) avait pour objectifs d'élaborer et tester un schéma d'évaluation par étapes pour des sites d'accumulation de sédiments. Nous présentons ici la démarche proposée, structurée en 3 étapes, et les résultats d'un test de celle-ci sur 17 sites. Il s'agit de répondre à deux questions : « les contaminants présents dans les sédiments (a) présentent-ils un danger probable pour les invertébrés benthiques (effet toxique direct), ou (b) ceux qui sont reconnus comme bioaccumulables ou bioamplifiables sont-ils présents à un niveau préoccupant » ? Chaque étape peut se conclure par l'arrêt de l'évaluation, si les données obtenues sont concluantes. La confrontation des résultats d'analyses chimiques interprétés à l'aide de seuils de toxicité ou d'indices de contamination aux résultats des tests de toxicité a permis d'illustrer la validité de la démarche, et de proposer des choix pour l'interprétation (entre indices ou classification sur la base du paramètre le plus pénalisant). Ce test a permis de montrer une bonne cohérence d'ensemble des éléments de preuve de toxicité rassemblés pour les 17 sites. Ce résultat mériterait d'être vérifié sur un plus grand nombre de sites, incluant des substances organiques plus variées et atteignant des niveaux de contamination plus élevés. Towards a tiered framework for an ecotoxicological hazard assessment of fluvial sediments -presentation and early testsABSTRACT. -Sediments are an essential component of fluvial ecosystems. They are also quite often a cause of disturbance for fluvial works, such as dams or locks. In order to manage these disturbances without causing adverse impacts downstream, managers should have in hand an efficient assessment framework. The DIESE project (tools for sediment ecotoxicity assessment) aimed to elaborate and test a tiered assessment framework for freshwater sediment sites. We present hereafter the proposed framework, and a pilot test on 17 sites. Basically, the framework intends to provide answers to 2 questions, namely (a) does the sediment contamination present a hazard to benthic invertebrates, and (b) if bioaccumulative/biomagnified contaminants are present, is their concentration worrying? The assessment process can end at any tier, provided the data are conclusive. Sediment quality benchmarks or contamination indices were used to interpret chemical analyses; this assessment was then compared to the results of ecotoxicity tests. Overall, the framework appears consistent; this test also helped selecting the best options for interpretation. Nevertheless, the test included only 17 sites, with a limited array of contaminants; complementary tests including more organ...

“…Indeed, they are restricted to this compartment, display low mobility and their trophic mode is primarily collector, based on the ingestion of fine sediments. In addition, the group includes a large number of species presenting a wide range of pollution sensitivity [10], and oligochaetes are generally abundant in sediments [11]. Different biological indices based on the study of the structure of oligochaete communities have been proposed for the assessment of the biological quality of stream and lake sediments.…”

“…Among the large panel of contaminants that can impact aquatic ecosystems, metals are considered important because they are still largely released by human activities (multiple sources) and are persistent [3,13]. Metals are often monitored in the sediment compartment, and it is therefore essential to define suitable thresholds of metal effects for helping in sediment quality assessment and management [11]. To this end, oligochaete metrics were specifically tested for defining effect thresholds for metals in Switzerland by Vivien et al [11].…”

Aquatic oligochaetes, comprising a large number of species showing various degrees of resistance to chemical pollution, are recognized as valuable bioindicators of sediments’ quality. In the Geneva area (Switzerland), oligochaete tools were previously tested for assessing the biological quality of stream sediments, and effect thresholds of combined metals (quotients) in sediments were defined. The aims of the present study were to update this previous work with new data acquired in different cantons of Switzerland and to establish effect thresholds on oligochaete communities for individual metals and for combined metals. The oligochaete metrics “Oligochaete index of sediment bioindication (IOBS)”, “oligochaete density” and “percentage of tubificids without hair setae” proved pertinent for assessing the effects of metals and organic matter in sediments. We established a threshold effect level (TELoligo) and probable effect level (PELoligo) for eight metals in sediments (Cr, Ni, Zn, Cu, Pb, Cd, Hg and As) as well as a probable effect level for these metals combined (mPELoligo-Q). These thresholds could be used directly to screen for alteration of in situ communities restricted to sediments and/or for establishing sediment quality standards based on a combination of different biological and ecotoxicological tools.
