Transfert des pesticides et métaux dans un petit bassin versant viticole. Étude préliminaire de l'influence des conditions hydrologiques sur le transport de ces contaminants

Abstract : The implementation of the European water framework directive implies the intensification of contaminants monitoring, identification of the causes of degradation and implementation of corrective actions to reach a good chemical and biological status by 2015. The aim of the present study is on the one hand, to evaluate concentrations and fluxes of pesticides and metals in a small stream draining an agricultural watershed located in the Beaujolais area and on the other hand, to define a sampling strategy adapted for an accurate evaluation of exposition to these contaminants. The estimation of pesticide fluxes passing through the river during flood events and during grab sampling showed that a single flood event can transport as much pesticides as those mobilized during one month in baseflow.
