PESTIPOND: a focused 48-month innovative collaborative research project associating 4 research units in France, and 15 socio-economic partners.
The innovative concept of the agricultural pond-centered PESTIPOND workflow is to constrain in situ processes of pesticide transformation in pond compartments to feed into an integrative modelling framework of risk and spatial predictions of pesticide transfer at the catchment scale, including the cumulative role of inter-connected ponds. PESTIPOND will target factors and processes controlling the pond capacities to degrade mixtures of pesticides, far beyond their primary role of delaying pesticide transfer or transforming parent molecules into transformation products. PESTIPOND is organized in 3 tasks:
- (T1) Biogeochemistry of pesticide behavior under field conditions;
- (T2) Pesticide dissipation pathways in ponds;
- (T3) Modelling assessment of the impact of ponds on pesticide transfer to surface waters.
The project partners have access to
experimental ponds, implanted in catchments belonging to IR OZCAR and IR RZA (French
LTSER), in 3 French regions : Auradé in Gascogne, Hohrain in Alsace and
Rampillon in Brie. EcoLab is in charge of Auradé catchment and of Sub-Task 1.3.
The postdoc will be focused on T1 by
investigating different ponds located in and around Auradé catchment, and will contribute
to some experiments in T2.
set up an experimental sampling design for one or two selected ponds to measure
the input-output concentrations of selected pesticides, MES and nutrients and
water discharge during one year. To follow high resolution measurements using a
probe with different sensors and to calibrate the field values by laboratory
collect and analyse the pesticide contents and physico-chemical parameters in
the different compartments of the ponds (water column, bottom sediments, plants
living in the ponds) during 2 contrasted seasons and a major hydrological event.
participate with the engineer in charge of the analytical platform to the
preparation of the samples and to the analyses of pesticides with GC-MS/MS
Triple Quadrupole with a thermal desorption.
participate to the the different scientific meetings and to exchange with the
researchers, postdoctorates and PhD working in the different laboratories
involved in PESTIPOND.
treat the data, to communicate them during the meetings and to participate to
the annual report and to prepare peerreviewed scientific publications and
presentations for scientific conferences.

The postdoc will be based at EcoLab which
is a joint research unit between CNRS- UPS Toulouse 3 and Toulouse INP.
The work is located at Auzeville-Tolosane
in the Campus of ENSAT. The researches in field will concern the Aurade catchment
and the surrounding areas, located 40 km from Toulouse.
