Abstract

Glyphosate is the most widely used pesticide in Alberta and has been detected in surface waters around the province. This presentation describes part of a study conducted to determine the possible pathways for glyphosate to enter these waterways. Following a spray event, air, particulate matter and soil were tested to determine residual concentrations from a sprayed field.
