Abstract
Air contamination by Plant Protection Products (PPPs) carries significant risks for human health.
Crop protection spraying induces air contamination, mainly in fruit production.
In 2001, observations showed important transfers during and after spraying (direct losses vs. volatilization from soil and crop), downwind a productive vineyard.
At the human scale the resulting exposure is difficult to measure because the PPPs concentration vary greatly in space and time.
In consequence, researches are focused on coupling simulation tools and data to estimate properly the air contamination.
Experimentations are conducted at fieldscale and labscale.
The objective is to improve the methodology on air sampling and to develop analysis tools dedicated to population protection and spraying optimisation recommendation.
