Abstract

The agricultural landscape constitutes a mosaic of various crop plots intertwined with non-disturbed natural areas. Extensive use of pesticide spraying can pollute the natural areas, causing damage to the natural food webs. The damages to the natural systems can be temporary and cumulative. Although many studies have dealt with the results of pesticide spraying drift to the natural environment, we lack knowledge on the role of dust particle transfer of pesticides. The study aims to investigate the dust particles as pesticide carriers. It examines the presence and accumulation of pesticides in vegetation and soils of the farmlands and natural areas nearby in two different climatic zones, Mediterranean and semiarid. It was hypothesized that seasonal agricultural activities affect the transport of dust particles with pesticides. The research methods included qualitative and quantitative analyses of pesticides in a hierarchy of distances from agriculture fields into natural and nearby. The renewal of the results indicated that seasonal agricultural activity leading to the transport of dust particles was a major contribution to the spatial distribution of pesticides, in both climate zones. Here we reveal results that must be an essential principle in the use of pesticides in agricultural fields, especially in nearby uninhabited areas.
