La contamination des \u00e9cosyst\u00e8mes par les pesticides utilis\u00e9s en agriculture concerne l’ensemble des compartiments \u00e9cologiques (atmosph\u00e8re, sol, aquif\u00e8res, masses d’eau). Le projet vise le d\u00e9veloppement et J’\u00e9valuation d’une mod\u00e9lisation int\u00e9gr\u00e9e du devenir des pesticides, \u00e0 l’\u00e9chelle du paysage, dans les diff\u00e9rents compartiments environnementaux. Il concerne le cas sp\u00e9cifique de paysages viticoles, dont l’\u00e9tude est consid\u00e9r\u00e9e comme prioritaire par l’Agence nationale de s\u00e9curit\u00e9 sanitaire de l’alimentation, de l’environnement et du travail. L’identification et la mod\u00e9lisation des voies de dispersion, de leurs d\u00e9terminismes et de leurs contributions relatives, en fonction des caract\u00e9ristiques de milieu, des pratiques culturales et d’application et des propri\u00e9t\u00e9s des mol\u00e9cules, est essentielle pour diagnostiquer les risques de contamination et d’exposition et rechercher des d\u00e9marches de r\u00e9duction de la contamination.<\/p>\n
Le projet comprend 4 actions : i) D\u00e9veloppement du mod\u00e8le int\u00e9gr\u00e9 ; ii) D\u00e9veloppement d’une base de donn\u00e9es ad hoc sur les dynamiques de contamination de l’air, du sol et de l’eau dans un paysage viticole m\u00e9diterran\u00e9en ; iii) Analyse de sensibilit\u00e9, calibration et confrontation de la mod\u00e9lisation aux situations exp\u00e9rimentales test; iv) Evaluation des contributions relatives des diff\u00e9rentes voies de transfert \u00e0 la contamination des ressources en sols et en eau de surface et \u00e0 l’exposition des riverains dans le cas d’un paysage viticole test.<\/p>\n","protected":false},"author":1,"featured_media":0,"template":"","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"default","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"categories":[82],"class_list":["post-1615","projets-de-recherche","type-projets-de-recherche","status-publish","hentry","category-projet-termine"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.umr-lisah.fr\/fr\/wp-json\/wp\/v2\/projets-de-recherche\/1615","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.umr-lisah.fr\/fr\/wp-json\/wp\/v2\/projets-de-recherche"}],"about":[{"href":"https:\/\/www.umr-lisah.fr\/fr\/wp-json\/wp\/v2\/types\/projets-de-recherche"}],"author":[{"embeddable":true,"href":"https:\/\/www.umr-lisah.fr\/fr\/wp-json\/wp\/v2\/users\/1"}],"version-history":[{"count":0,"href":"https:\/\/www.umr-lisah.fr\/fr\/wp-json\/wp\/v2\/projets-de-recherche\/1615\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.umr-lisah.fr\/fr\/wp-json\/wp\/v2\/media?parent=1615"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.umr-lisah.fr\/fr\/wp-json\/wp\/v2\/categories?post=1615"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
