Abstract:
|
Minimization of the risk associated with spray applications requires a proper understanding of the spray drift
phenomenon. This fact has led to the development of several techniques to measure the deposition on horizontal surfaces
as well as the airborne spray profiles. Assessment of airborne spray drift is particularly difficult because this
phenomenon is subject to variable micrometeorological conditions. However the monitoring of airborne drift has a great
importance since it can be carried over long distances. This paper reviews main sampling techniques currently used to
asses the airborne spray drift, based on passive collectors and tracers. Theoretical principles that determine the efficiency
of passive samplers are studied as well as the performance of different types of tracers. On the other hand, this paper
shows new airborne spray drift assessment techniques based on lidar technology, reviewing its principle of operation as
well as its practical application in several spray drift trials. It is concluded that the lidar technique has significant
advantages over conventional methods, especially in terms of time consumption and monitoring capabilities. However,
the future adoption of lidar technology for airborne spray drift studies will be subjected to the development of lidar
instruments really adapted to this application. |
