Pesticides: criticisms of the regulation that allows poisoning the country

Abstract

The article contains an analysis of the marketing authorizations and the consumption of pesticides in the last decade, as well as their effects on human health and the environment. In the period between 2010 and 2018, the amount of pesticides sold in Brazil increased more than twice as much as the cultivated area in the country. The permissiveness of pesticide governance in Brazil is illustrated by the fact that, of the total chemical active ingredients with register in the country in July 2020, 121 (30.0%) had no use allowed in the European Union (EU). The reason for the ban on the use in the EU of products authorized in Brazil, in the referred period, is associated with the adverse effects on humans and other organisms resulting from exposure to chemical ingredients of pesticides, already described in the scientific literature. Soybean, corn, cotton and sugar cane are among those that had the largest number of new pesticides authorized for use in Brazil between January 2019 and June 2020. Another lack of rigor in pesticide governance is illustrated by the drift, which causes acute and chronic damage to third parties. Another weakness of the Brazilian standard refers to the establishment of a dose value, below which, they would be safe. However, experimental results from studies have shown, for example, that pesticides based on glyphosate, melation and pyriproxifem caused the death of fish embryos in just 24 hours of exposure, regardless of the concentration used, challenging the hypotheses that there is safe dose for exposure to such pesticides. Thus, it is urgent that there is a need not only to increase the scientific rigor of the studies on the subject, but also to promote the public participation in decision-making process ensuring the access to all information contained in the dossiers accompanying requests for registration and authorization.
