Pesticides environmental destination: a study based on coffee productive areas

The benefits of pesticides are evident. However, the risk of adverse effects must be diminished. So, it is necessary to exert effective control of use and have available methods of calculating their environmental behavior. The models employ calculations that use concepts of activity and fugacity to characterize the equilibrium that exists between environmental compartments. Most of the emphasis is set on organic chemicals, which are more susceptible to generalization than inorganic chemical, when assessing environmental behavior.
