Abstract

This study aims to provide a diagnosis of 2,4-D in Brazil, based on its environmental fate, sales, spatial distribution, and concentrations in raw and drinking water. An estimate of 2,4-D sales in Brazilian municipalities and states was conducted, considering data on planted area, sales, and authorized use in the country. The concentration of 2,4-D was analyzed through a systematic literature review and data processing from SISAGUA. It was found that 2,4-D shows a tendency for increased commercialization, with an annual average of 43,267 tons and an average usage rate per planted area of 0.65 kg/ha, with some notable regions. 2,4-D showed a high detection frequency, with values that, overall, did not exceed the maximum acceptable value (MAV) for drinking water in Brazil. It is concluded that 2,4-D is widely used and detected, however, this fact does not currently reflect a risk to human health through drinking water consumption.
