Autores: Fermam,   Ricardo Kropf Santos; Antunes,   Adelaide Maria de Souza.
Pesticides play an important role in agriculture, prevent loses by pests which destroy cultures and causes several damages to producers and to exporting countries of agriculture products. However, pesticides leave residues where they are used. A parameter used for residue quantification is known Maximum Residue Limit (MRL). This parameter is the most important, not only in terms of public health, but mainly international trade, causing many impacts that can represent, in some cases, barriers to trade between countries, especially when established values for a country differ from those established by international organizations. The present Article show how this parameter impacts agriculture products´ trade of developing countries, based on case study.
