Analysis of Pesticides: a First Study toward a Smart Analysis

In this paper we propose to evaluate the amount of a specific set of pesticides/herbicides from the evaporation or desorption of harmful molecules from the soil. The aim of this work is focused on the definition of reliable pattern that can be detected by disposable gas sensors in order to create a robust gas sensor network for a real time monitoring of vast agricultural areas. As first results we discussed a new automatic procedure for pesticides analysis implemented to define a comparing table to be matched by the as sensors responses. In particular, we analyzed two common pesticides (Chlorpyrifos and Pendimethalin) by measuring their desorption from fibers placed in contaminated soil for different times
