Avaliação de agrotóxicos com potencial carcinogênico com uso no Brasil

Abstract

The use of pesticides in Brazilian agriculture has raised concerns due to their carcinogenic potential and associated environmental impacts. This study aimed to evaluate pesticides with carcinogenic potential that were marketed in Brazil between 2009 and 2022, using data from the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA) and the National Health Surveillance Agency (ANVISA), as well as classifications from the International Agency for Research on Cancer (IARC) and the United States Environmental Protection Agency (USEPA). A total of 25 active ingredients with the highest carcinogenic potential were identified, 14 of which had proposed maximum acceptable values (MAVs) for drinking water. The adopted methodology included an analysis of toxicity, commercialization, soil mobility, and leaching potential, considering environmental factors and human exposure. The results showed that pesticides such as propineb and imazalil present a high risk of exposure due to their large commercialization volume and potential for environmental transport. The findings of this study reinforce the need for continuous monitoring and periodic review of current regulations to mitigate public health risks. Additionally, they highlight the importance of implementing strict public policies for the management and control of pesticide use in Brazil, aiming to minimize the contamination of surface and groundwater sources.
