Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

Objective:

To describe the profile of exogenous pesticide poisoning notifications in Rio Grande do Sul, Brazil, from 2011 to 2018.

Methods:

This was a descriptive study of data retrieved from the Notifiable Health Conditions Information System. Sociodemographic, clinical and pesticide-related variables were included and presented in absolute and relative frequencies.

Results:

3,122 suspected cases of exogenous pesticide poisoning were reported. The main toxic agent was pesticide for agricultural use (60%). Spraying (42%) and dilution (18%) proved to be the activities with greatest pesticide exposure. Most pesticide poisoning occurred at home (59%), and accidental contamination (40%) was the main cause of poisoning. Most poisoning was of the acute single kind (82%) and clinical evaluation (61%) was the criterion most used for diagnosis.

Conclusion:

Most of records of exogenous pesticide poisoning in Rio Grande do Sul were related to its agricultural production model.
