The Brazilian legislation does not provide for a periodic review of the registration of pesticides and, even nowadays, products banned in other countries are still used. Based on the pesticide active substances registered in the country, the present study investigated the international regulatory situation in the following member countries: Organization for Economic Co-operation and Development (OECD), European Community, and the BRICS (Brazil, Russia, India, China, and South Africa). Moreover, we sought to relate the main chronic effects to human health and the environment of the most commercialized pesticide active substances in Brazil in lists of classification of carcinogenic potential (US Environmental Protection Agency - USEPA and International Agency for Research on Cancer - IARC), endocrine disruption, and candidates for substitution, both from the European Community. A total of 399 pesticide active substances registered in Brazil for agricultural use were identified, excluding microbiological and biological control agents. Of these, the percentage of unauthorized pesticide active substances according to countries is as follows: 85.7% in Iceland; 84.7% in Norway; 54.5% in Switzerland; 52.6% in India; 45.6% in Turkey; 44.4% in Israel; 43.4% in New Zealand; 42.4% in Japan; 41.5% in the European Community; 39.6% in Canada; 38.6% in China; 35.8% in Chile; 31.6% in Mexico; 28.6% in Australia; and 25.6% in the United States. 120 pesticide active substances were related to damage to health and the environment. Considering the pesticide active substances for which commercialization data are available in the country, 67.2% of this volume is associated with at least one serious chronic damage assessed in this study. The results of the present study indicate the need for promoting transparency of international databases, regarding the motivations of the respective regulatory decisions and the Brazilian regulatory bodies to reevaluate the registration of obsolete products and to strengthen public policies related to the reduction of the use of pesticides.
