### Contamination en cuivre des sols viticoles

En France, l'utilisation du cuivre en tant que fongicide contre le mildiou de la vigne (Plasmopara viticola) remonte à 1882 avec l'invention de la bouillie bordelaise (Ca(OH)₂+CuSO₄). Le cuivre est la seule substance efficace pour la lutte contre le mildiou autorisée en agriculture biologique. Une polémique s'est ainsi développée sur l'usage de cet élément, écotoxique à forte dose, en agriculture biologique. Depuis 2018, les doses de cuivre appliquées sont règlementées pour tous les viticulteurs avec une dose maximale autorisée de 4 kg de cuivre/ha/an (soit 28 kg/ha sur 7 ans avec une possibilité de lissage). Des interrogations subsistent sur l'écotoxicité de cet élément dans les écosystèmes viticoles actuels en fonction de l'évolution des pratiques agricoles (réduction des doses, variabilité des formes et des formulations, etc.). L'objectif de cette fiche thématique est de faire un rapide état des lieux des connaissances sur l'écodynamique et l'écotoxicité du cuivre et de souligner les questions de recherche encore ouvertes.

### Un historique lourd de conséquences

Le cuivre dans les sols a une origine naturelle et anthropique. Les teneurs actuelles de cuivre dans des sols sont le résultat de l'accumulation de différentes sources (fond pédogéochimique, retombées anthropiques, effluents d'élevage, déchets, traitements phytosanitaires). Une analyse des sols européens (Ballabio et al., 2018) a montré que les sites les plus concentrés en cuivre sont des sols viticoles (49 mg/kg en moyenne). Dans le cas des sols viticoles, ce sont essentiellement les apports de produits phytosanitaires qui sont à l'origine de l'accumulation du cuivre, même si d'autres types d'apports sont parfois non négligeables, comme c'est le cas pour l'épandage de composts de déchets ménagers qui a été fréquent dans certaines régions dans les années 70-90. Les horizons de surface des sols viticoles français ont des teneurs variant de quelques dizaines à plusieurs centaines de mg/kg. Les teneurs mesurées aujourd'hui sont le résultat des applications passées.

<figure><img src="image_50.png" /></figure>

Figure 1. Relation significative (p < 0,001) entre l'âge viticole des sols et la teneur en cuivre de leur horizon de surface (0-15 cm) Le nombre d'années en usage viticole de chaque parcelle résulte de l'analyse de photographies aériennes (https://remonterletemps.ign.fr/). En vert sont les parcelles conduites en agriculture biologique et en rouge celles conduites en agriculture conventionnelle.

L'analyse d'une centaine de sols provenant de différentes régions viticoles (Anatole Monnier, 2014 ; Pierdet, 2020 ; Blondel, 2021 ; Ouedraogo, 2022) a permis de dégager une relation entre le nombre d'années pendant lesquelles le sol a été cultivé en vigne et la teneur en cuivre mesurée aujourd'hui dans l'horizon de surface (Figure 1). Dans ce panel, aucune différence significative n'est apparue entre les sols cultivés aujourd'hui en agriculture biologique et en agriculture conventionnelle. Ce résultat est logique car les teneurs mesurées aujourd'hui sont en fait le résultat de l'usage passé des sols. Les viticulteurs doivent donc gérer au mieux une situation dont ils ont hérité, sans continuer à la dégrader.
### Mobile ou immobile : le cuivre migre-t-il dans les sols ?

De fait de sa très forte affinité pour la matière organique, le cuivre s'accumule préférentiellement dans l'horizon superficiel des sols. De manière générale, il est admis qu'il a une faible mobilité dans les sols. Dans les sols sableux et acides, un transfert du cuivre peut néanmoins être observé vers des horizons d'accumulation plus profonds – transfert vertical dont l'importance dépend aussi de la pluviométrie (Mirlean et al., 2007). Cependant, dans les sols viticoles chaulés, ce transfert vertical du cuivre semble limité. L'incorporation du cuivre dans le profil est par contre notable suite au labour avant replantation. Ce labour, qui va enfouir la couche de surface, modifie la distribution du cuivre dans le sol créant parfois des couches contaminées vers 30 à 40 cm de profondeur (Brun et al., 1998; Pierdet, 2020). Le labour profond peut aussi affecter l'agrégation et le lessivage particulaire, favoriser la minéralisation de la matière organique ou modifier l'adsorption du cuivre sur les constituants du sol, tous ces processus favorisant les transferts en profondeur.

Le cuivre étant fortement retenu en surface dans les sols, ses transferts superficiels se font essentiellement par érosion de surface et ruissellement, notamment dans les vignobles en pente non enherbés. Les concentrations en cuivre dans les eaux de ruissellement sont bien plus élevées, parfois de plus d'un facteur 20, que dans les eaux d'infiltration (Banas et al., 2010). Malgré cela, la quantité de cuivre exportée par ruissellement reste très faible comparée à la quantité totale de cuivre dans les sols. Le traçage isotopique du cuivre dans un bassin versant a permis d'estimer à environ 1 % la part de cuivre total transférée par ruissellement, dont seulement 16 % sous forme dissoute (Babcsányi et al., 2016). Il apparaît donc que, dans les sols viticoles, l'homme est un vecteur important de la dissémination du cuivre de par les pratiques agronomiques de labour et de désherbage en inter-rang ou sous le rang.

### Phytotoxicité du cuivre

Le cuivre est un oligo-élément pour les plantes car il est nécessaire à l'action d'enzymes impliquées dans des fonctions physiologiques diverses telles que la respiration, la photosynthèse ou le métabolisme de la paroi des cellules. Au-delà d'un certain seuil, il devient toxique, perturbant le fonctionnement physiologique de la plante jusqu'à sa létalité. Cette toxicité à relativement faible dose s'explique, notamment, par ses propriétés redox qui lui confèrent un fort pouvoir oxydant, et son aptitude à déplacer d'autres ions métalliques de leurs cibles physiologiques, tel que le fer.

La forme chimique absorbée par les racines des plantes est la forme ionique : l'ion Cu²+ est réduit en ion Cu⁺ à la surface des racines avant d'être internalisé par des transporteurs dédiés. Le cuivre prélevé s'accumule principalement dans les racines. Les racines sont l'organe « tampon » qui stocke et détoxifie le cuivre lorsque celui-ci est présent en excès dans le sol et ce, jusqu'à une concentration critique variable selon la tolérance des plantes au cuivre. Au-delà, le cuivre provoque une « rhizotoxicité » qui se traduit par un épaississement, un brunissement et un raccourcissement des racines ainsi que par une diminution de leur ramification. Au niveau des organes aériens, la phytotoxicité cuprique se traduit par un jaunissement intervernaire du limbe foliaire, que l'on attribue le plus souvent à une déficience induite en fer.

Il est compliqué de définir des seuils de phytotoxicité de contaminants dans les sols car ceux-ci dépendent fortement de la méthodologie suivie. Dans la plupart des travaux menés sur le cuivre, du cuivre frais est apporté au sol et des végétaux sont cultivés, soit immédiatement après l'apport soit après un temps d'équilibre permettant au cuivre de se redistribuer sur les différentes phases. Les paramètres suivis sont l'elongation racinaire ou la biomasse produite. Les seuils de phytotoxicité résultants sont très variables selon les sols (tableau 1) lorsque ceux-ci sont exprimés en teneur totale de cuivre dans le sol, i.e. sans tenir compte de sa disponibilité. Fort logiquement, ces valeurs seuils dépendent étroitement des caractéristiques du sol influant sur la disponibilité du cuivre que sont le
pH, la CEC, la teneur en matière organique ou en oxydes de fer (Rooney et al., 2008). Les seuils les plus bas sont d'ailleurs peu réalistes car ils correspondent à des teneurs du fond pédogéochimique.

A notre connaissance, peu d'études visant à déterminer les seuils de phytotoxicité de cuivre dans les sols ont intégré des indicateurs de disponibilité du cuivre tels que les teneurs extractibles par un extractant chimique, les concentrations en cuivre (total ou ionique) dans l'eau porale du sol ou les quantités accumulées par un capteur passif de type DGT. Par contre, des seuils de phytotoxicité ont été obtenus à partir de cultures hydroponiques, avec l'objectif de comparer à ces seuils les concentrations en cuivre (total ou ionique) mesurées dans l'eau porale des sols. Cette idée repose sur la relation étroite observée dans certaines études entre la concentration en cuivre (total ou ionique) de l'eau porale des sols et ses effets phytotoxiques (Lock et Janssen, 2003 ; Kader et al., 2016). Le tableau 2 présente des valeurs seuil de toxicité cuprique, exprimées en concentration de cuivre (total ou ionique), en solution pour différentes plantes. En comparant avec les concentrations mesurées dans l'eau porale des sols viticoles ces valeurs sont dépassées dans certains sols acides fortement contaminés en cuivre (Ouedraogo et al., 2020).

## Toxicité du cuivre pour la faune et les microorganismes du sol

L'accumulation de cuivre peut avoir des effets négatifs sur les organismes du sol constituant la méso ou microfaune et la microflore. A forte concentration, le cuivre peut impacter la survie des organismes. A plus faible concentration, il altère leur croissance et leur reproduction, comme observé que vers de terre, enchytrées et collemboles (Sørensen et Holmstrup, 2005 ; Ruyters et al., 2013). La reproduction s'avère être le paramètre le plus sensible à la contamination. Les effets génotoxiques et cytotoxiques semblent variables selon les espèces, le temps d'exposition et les formes chimiques du cuivre apporté
(Wang et al., 2018). Le comportement des organismes est aussi impacté par la contamination cuprique, les vers de terre et les enchytrées ayant des stratégies d'évitement des zones les plus contaminées (Bart et al. 2017). L'abondance et la diversité des organismes du sol sont aussi affectées par l'accumulation de cuivre. Certaines espèces sont plus tolérantes que d'autres comme cela a été montré pour les enchytrées *Enchytraeus albidus* et *Enchytraeus luxurious* (de Barros Amorim et al., 2005) ou les collemboles *Folsomia candida*, *Sinella communis* et *Proisotoma minuta* (Greenslade et Vaughan, 2002). En conséquence, la biodiversité varie avec le niveau de contamination.

Une récente synthèse de l'impact écotoxique du cuivre sur la biodiversité tellurique, et les échanges scientifiques qui en ont suivi, ont conclu « qu'une dose de 4 kg/ha/an ne présente pas de risque à court-terme pour la biodiversité des sols dans certains vignobles mais pourrait constituer une menace dès à présent dans les vignobles les plus vulnérables (forte accumulation historique, conditions spécifiques de pH et de matière organique des sols) » (Karimi et al., 2021a et b., Imfeld et al., 2021). En effet, autant voire plus que la dose de cuivre apporté, c'est sa disponibilité dans le sol – elle-même dépendante du pH, de la teneur en matières organiques (et autres phases sorbantes) et de la teneur en cuivre du sol récepteur, qu'il faut considérer. Cependant, les seuils de toxicité pour les espèces telluriques sont généralement exprimés en fonction de teneurs de cuivre total et non de valeurs de disponibilité. D'autre part, la plupart des évaluations des seuils écotoxicologiques sont réalisées en laboratoire, avec des espèces modèles comme le ver du fumier *Eisenia fetida*, qui ne se retrouvent pas dans les sols viticoles. Nous manquons de références sur les espèces effectivement présentes dans les sols.

La courte durée des biotests, l'utilisation de sols artificiels ou de forme chimique simple peuvent mal estimer l'écotoxicité du métal par rapport à une application au champ d'une formulation phytopharmaceutique commerciale. La disponibilité diminue également en fonction du temps écoulé après l'apport de cuivre par le phénomène appelé « vieillissement » qui correspond au changement de spéciation du métal et à son adsorption progressive sur les phases solides (Daoust, 2006, Ruyters et al., 2013). Par conséquent, les seuils de toxicité Cu peuvent être très divers selon les sols testés (tableau 3). Cette variabilité s'explique par une variabilité importante de la disponibilité du cuivre entre les sols testés en lien avec un différentiel de pH, de teneur en matières organiques (ou en oxydes) et/ou de CEC.

## Fiche thématique N°40 - Aout 2022

<figure><img src="image_51.png" /></figure>

Pour les micro-organismes du sol, la respiration, l'abondance et la diversité sont affectées par la contamination en cuivre (Scott-Fordsmand et al., 2000 ; de Barros Amorim et al., 2005 ; Fernández-Calviño et al., 2010). Les communautés fongiques semblent plus tolérantes que les communautés bactériennes, leur croissance étant affectée à des doses plus élevées (Vázquez-Blanco et al. 2020). Les activités enzymatiques des communautés microbiennes sont perturbées par l'excès de cuivre (Fernández-Calviño et al., 2010 ; Mackie et al., 2013), modifiant ainsi le fonctionnement des sols. Les activités enzymatiques semblent être les paramètres les plus sensibles pour rendre compte d'un effet sur les communautés microbiennes des sols. Pour tous ces paramètres, là encore, la teneur totale induisant un effet varie très fortement selon les sols. Le pH apparaît comme un facteur clef dans la composition de ces communautés et leur résistance au cuivre (Vázquez-Blanco et al., 2020) tout comme la teneur en matières organiques ou la texture du sol (Soler-Rovira et al., 2013). Il semble donc pertinent de ne pas raisonner par rapport à la teneur totale en cuivre mais bien par rapport à la teneur disponible. Ces références manquent actuellement.

## Les questions de recherche à approfondir

Les processus contrôlant l'écodynamique du cuivre dans les sols en contexte viticoles sont aujourd'hui bien connus mais ils sont insuffisamment quantifiés dans ces milieux à forte variabilité spatiale. Les flux vers les aquifères superficiels ou profonds sont également rarement estimés. L'importance de la variabilité temporelle des échanges sol-solution et des transferts vers ces aquifères a été identifiée mais sa modélisation, en fonction de l'environnement pédoclimatique, reste à construire. La quantification de ces transferts entre le milieu terrestre et le milieu aquatique est cependant essentielle pour permettre de tester des scénarios d'évolution des pratiques ou d'impact des changements climatiques et aussi de prédire l'écotoxicité potentielle pour les organismes aquatiques.

La toxicité du cuivre est également connue, même si certains processus nécessitent encore des études approfondies. Cependant le lien entre la disponibilité du cuivre et son écotoxicité est insuffisamment étudié. Notamment, nous manquons de références et des méthodes d'évaluation fiables qui permettraient d'orienter les professionnels et de clairement identifier les sols où le cuivre pose un problème d'écotoxicité. Il est essentiel de construire rapidement ces références en reliant les connaissances sur la spéciation du cuivre dans les sols à celles sur son effet sur les organismes et les communautés.

Enfin, les études réalisées, sur lesquelles s'appuient les règlementations, testent de fortes doses, irréalistes par rapport aux pratiques actuelles d'application du cuivre en viticulture. Il semble important d'étudier les effets écotoxiques potentiels à des doses réalistes, et dans des conditions de terrain.

# Une première approche de l'histoire de l'écotoxicologie à l'INRA et Irstea

## Introduction

L'utilisation de produits chimiques par l'Homme s'est fortement accrue depuis la seconde guerre mondiale. En opposition avec la notion de progrès qui a accompagné cette évolution, les produits chimiques n'ont pas tardé à contaminer les milieux naturels, puis à impacter les êtres vivants. Le livre « Le printemps silencieux » (Carson, 1962), dont nous célébrons cette année le 60ème anniversaire, a dénoncé cet état de fait, puis initié les préoccupations environnementales de la société, posant même les bases d'une nouvelle discipline scientifique, l'écotoxicologie.

Au niveau universitaire français, c'est à Jean-Michel Jouany (Professeur de la Faculté de Pharmacie de Nancy) que l'on doit le terme d'écotoxicologie, écrit pour la première fois en 1971 dans son article « Ecologie et nuisances », et introduit par cette simple phrase : « L'étude de l'influence des nuisances sur les relations individu-environnement pourrait être simplement qualifiée d'Ecotoxicologie » (Jouany, 1971). J.-M. Jouany et R. Truhaut (Professeur de la Faculté de Pharmacie de Paris) définiront ensuite l'écotoxicologie comme une science multidisciplinaire qui « étudie les effets délétères des agents chimiques, physiques et biologiques sur l'ensemble des êtres vivants, ainsi que leurs interrelations au sein des communautés et leur interaction avec l'environnement » (Truhaut et Jouany, 1977). Durant la même période, François Ramade (Professeur d'Ecologie de l'Université Paris-Sud) aura aussi un rôle actif dans le développement de l'écotoxicologie, en particulier par ses nombreux ouvrages, dont « Ecotoxicologie » (Ramade, 1977).

## Comment des instituts de recherche tels que l'INRA et Irstea se sont-ils organisés pour répondre aux enjeux des recherches en écotoxicologie ?

Le réseau ECOTOX s'est associé avec le Comité INRAE/Cirad pour l'histoire de la recherche sur l'agriculture, l'alimentation et l'environnement, pour initier en 2020 un travail de recherche visant à présenter l'évolution de la réflexion scientifique et de l'organisation du dispositif de recherche et d'expertise en écotoxicologie au sein de l'INRA et d'Irstea. Cette première recherche, rendue possible par le recrutement de M1 puis en M2 d'Andréa Demonfaucon, étudiante en Master d'Histoire Moderne et Contemporaine, Parcours Construction des Sociétés Contemporaines (CSC) de l'Université Lumière-Lyon 2, a apporté un regard d'historienne sur ses aspects. Sa démarche s'est organisée autour de trois étapes :

- recherche et centralisation de sources écrites au sein des instituts

- entretien avec les acteurs

- rédaction de livrables.

Ce travail de recherche, encadré par P. Cornu et E. Valceschini, membres du Comité, avec l'appui de J. Garric (ex Irstea) et de C. Mougin (ex INRA), a permis de distinguer 3 grandes périodes dans cette histoire de l'écotoxicologie au sein de nos instituts.
## Le Temps de l'imperceptibilité des polluants : entre réglementation et tâtonnements scientifiques de l'écotoxicologie - 1980-1994

A partir des années 1970, notamment en raison des impacts des accidents industriels, la dégradation de la qualité de l'eau et des milieux aquatiques est devenue un enjeu de recherche et de législation. Dans ce contexte, le Centre technique du génie rural des eaux et des forêts (Ctgref, intégré au Cemagref en 1981) a été l'un des premiers laboratoires à se positionner en France sur la recherche environnementale, notamment en écotoxicologie. Il s'appuie sur des travaux menés en partenariat avec EDF (notamment sur l'impact des effluents chlorés issus des systèmes de refroidissement des centrales thermiques), ou les Agences de l'eau pour les effluents industriels et urbains. Ces premiers travaux positionnent la gestion des eaux et des milieux aquatiques face aux pollutions comme un enjeu vital. Des collaborations sont également nouées avec l'Ifremer et l'INRA.

Mais la prise de conscience de l'impact des pollutions sur les différents compartiments de l'environnement reste hétérogène. La prise en compte des impacts des pollutions sur les milieux terrestres et notamment les sols est plus tardive. Elle s'effectue au travers de deux grandes problématiques, la procédure d'autorisation de mise sur le marché des produits phytosanitaires (avec la directive européenne 91/414), et la valorisation par épandage des boues d'épuration. Comme la réglementation en matière de protection des sols est très limitée, c'est à travers la réglementation des substances toxiques qu'il faut trouver des évolutions. L'expertise liée à l'homologation des pesticides devient un des champs d'expertise privilégié pour l'INRA dès les années 1980 et tout au long des années 1990, pour aboutir à la création de la Structure Scientifique Mixte en 1997.

## Le temps de la traque scientifique du devenir des polluants : les premiers pas de l'écotoxicologie institutionnelle - 1994-2006

Dans les années 1990, les forces en écotoxicologie sont peu nombreuses et dispersées sur l'ensemble du territoire national. Le Cemagref investit dans la création d'un Thème de Recherche (TR) permettant d'inclure l'ensemble des chercheurs concernés par le devenir et l'ilpact des pollutions chimiques, indépendamment de leur localisation, pour favoriser l'interdisciplinarité et coordonner les réponses aux appels à projets. Ainsi est créé en 1999 le TR EXPER « Effets des apports allochtones sur les milieux aquatiques. Facteurs d'exposition des organismes et perturbations des récepteurs biologiques » dédié aux questions d'écotoxicologie aquatique.

Le département de Phytopharmacie de l'INRA, longtemps en lien avec les instances en charge de l'homologation des produits phytosanitaires, a initié relativement tôt des recherches en écotoxicologie. Puis, dans les années 1990, une équipe pluridisciplinaire, Xénobiotiques et Environnement, voit à Versailles ses thématique de recherche évoluer de la dynamique des contaminants à la prise en compte de leurs impacts sur le vivant. Elle étudie également l'utilisation de champignons filamenteux comme agents de dépollution des sols. Elle propose comme perspectives le développement de bioindicateurs de la qualité biologique des sols. Les programmes nationaux portés par le PNETOX et l'ADEME sont des leviers importants.
### Le temps de la saisie scientifique des effets des polluants : l’âge d’or des réseaux en écotoxicologie - 2006 – Nos jours

La politique française de protection des ressources aquatiques se renforce de manière significative au cours de la décennie 2000. La Directive Cadre sur l’Eau (DCE) devient de plus en plus prégnante dans la gestion des eaux, renforçant la position des instituts de recherches sur la problématique des pollutions et de ses effets. Le Cemagref (devenu en 2012 l’Institut national de recherche en sciences et technologies pour l’environnement et l’agriculture, Irstea) met en place le TR BELCA « Réponses Biologiques et Ecologiques aux contaminations du milieu Aquatique : Ecotoxicologie et Bioindication ».
Sa finalité est de développer les connaissances sur l’impact des contaminations dans les milieux récepteurs, et de faire émerger des outils d’évaluation des dangers toxiques utilisables en support de la réglementation. Aux partenaires historiques de la gestion des milieux, s’ajoute également l’Office national de l’eau et des milieux aquatiques (ONEMA). Cet acteur national de la gestion des milieux aquatiques soutient également le réseau AQUAREF qui mobilise les instituts de recherche nationaux (dont l’INRA et Irstea) pour répondre à des questions critiques pour la surveillance des milieux aquatiques tant en chimie qu’en hydrobiologie, et satisfaire aux besoins de surveillance générés par la DCE. Le TR BELCA se termine avec la réorganisation d’Irstea en 2018, prélude à la fusion avec l’INRA.
Les travaux menés dans le TR BELCA, et par les partenaires scientifiques du domaine (CNRS, INRA, Ifremer, universités dont Metz et Bordeaux) ont permis de produire, entre 2016 et 2018 une série de livre sur l’écotoxicologie (https://www.istegroup.com/fr/series/ecotoxicologie/).

A la suite de la mission « écotoxicologie » confiée par l'INRA à J.-P. Cravedi en 2004, la création de l'unité « Physicochimie et écotoxicologie des sols d'agrosystèmes contaminés, PESSAC) est actée par l'INRA, avec la fusion de l'unité de Science du Sol et de l'équipe Xénobiotiques et Environnement de Versailles qui vise à structurer la communauté des écotoxicologues terrestres à l'INRA. Cette unité a pour mission forte d'assurer l'interdisciplinarité entre les chercheurs travaillant sur la dynamique des contaminants dans les sols et sur leurs impacts, en y associant des approches de modélisation. PESSAC jouera un rôle important en Ile de France en promouvant l'écotoxicologie au sein de la Fédération Ile de France de Recherche sur l'Environnement (FIRE) et du Labex Biodiversité, Agroécosystèmes, Sociétés, Climat (BASC). L'unité relancera également en 2010 les colloques de la Société d'Ecotoxicologie Fondamentale et Appliquée (SEFA). En 2015, l'UR PESSAC a fusionné avec l'UMR Environnement et Grande Cultures (EGC) pour former l'UMR Écologie fonctionnelle et écotoxicologie des agroécosystèmes (ECOSYS).

Les réseaux d'animation scientifique constituent d'autres leviers majeurs de la structuration du dispositif INRA, puis d'Irstea. Le réseau « Pesticides », actif entre 2001 et 2004 a mobilisé les acteurs de la recherche sur cette problématique, pour produire en 2004 l'ouvrage « Un point sur l'estimation des risques environnementaux des pesticides ».

Le réseau « Ecodynamique des micropolluants » (REM) créé dans la foulée s'adresse à une communauté scientifique qui s'intéresse à d'autres contaminants (métaux...). Sa finalité est d'instaurer un dialogue entre les chercheurs qui s'intéressent à la question de la dynamique des micropolluants, notamment dans le cadre de plusieurs écoles chercheurs (2005, 2006, 2009).

Le réseau des écotoxicologues de l'INRA, aujourd'hui réseau d'écotoxicologie terrestre et aquatique (ECOTOX) sera en 2009 une seconde conséquence de la mission Cravedi. Le réseau REM a intégré ECOTOX, qui mobilisera des chercheurs issus de plusieurs départements de l'INRA, puis d'Irstea, et est à ce jour un outil d'animation nationale reconnu., qui a permis la constitution du réseau EcotoxicoMic dédié à l'écotoxicologie microbienne. ECOTOX organise des séminaires trisannuels et offre un certain nombre de livrables (liste de diffusion, fiches thématiques, bulletins de veille, ouvrages, séminaires...). Enfin, le réseau se veut une interface entre les différentes structures traitant d'écotoxicologie u plan national, comme la Fondation Rovaltain ou encore la SEFA.

### En conclusion

L'écotoxicologie est une discipline relativement récente, en quête d'implantation durable dans la sphère scientifique et institutionnelle depuis le milieu des années 1970. Ces premiers travaux ont fourni des éléments pour retracer l'histoire des écotoxicologues au sein de l'INRA et d'Irstea pour aboutir aujourd'hui à la communauté INRAE. Aujourd'hui, INRAE peut s'appuyer sur des forces "renforcées" grâce à la fusion des 2 instituts.

Cependant, seule une faible partie émergée d'un vaste iceberg n'a été considérée. Ce choix a été guidé par les sources documentaires collectées et les entretiens réalisés, qu'il reste nécessaire de compléter, en considérant par exemple l'écotoxicologie aquatique au sein de l'INRA ou encore l'implication des chercheurs dans les différentes instances d'expertise.

« Conserver la nature, c'est aussi conserver l'homme ; il parait raisonnable de lutter contre la destruction des sols, d'augmenter les récoltes, de conserver les écosystèmes » (Jouany, 1971).
