Pesticides in fine airborne particles: from a green analysis method to atmospheric characterization and risk assessment

Abstract The intensive use of pesticides such as herbicides, insecticides, fungicides and acaricides has been lead to ubiquitous contamination, being present not only in soils, water bodies and/or crops, but also in the atmosphere. Considering the massive amount of pesticides employed globally, toge...
