Airborne Exposures Associated with Pesticide Applications at Farming Operations

Pesticides improve crop yield and quality, crucial for feeding the world’s population. However, airborne exposures to the people applying the pesticide and those near the application pose potential risks. Additionally, it is essential to manage emissions from pesticide applications in an environmentally responsible way.

There are different types of pesticides.  One class of fumigants is applied pre-plan (methyl bromide, metam sodium, chloropicrin, 1,3 dichloropropene, etc.).  Another form is less volatile pesticides, such as those used with crops in the field.  Additionally, there are non-volatile pesticides in powder form.  

Additionally, airborne exposures to both applicators and bystanders pose potential risks. Two methods for assessing human exposure to volatile pesticides are direct measurement and dispersion modeling. Dispersion modeling considers emission rates based on the pesticide, application, and sealing methods. Sullivan Environmental utilizes both approaches.

Direct Measurement: We’re excited to share that our dedicated team has completed over 60 field trials to assess pesticide emission rates during and after application.  Additionally, understanding fugitive emissions can be challenging as they fluctuate based on factors like time of day and downwind conditions.
