Recent water quality inventories show that agricultural non-point source pollution (NPS) is the leading source of water quality impacts to surveyed rivers and lakes, and also a major contributor to groundwater ontamination and wetlands degradation (Blankenberg et al.2006; Haarstad and Braskerud 2005; Bergstrom 2004; Thiere and Schulz 2004; Schreiber et al.2001; Huber et al. 2000; Luo and Zhang 2010). Pest management is one of the main scopes of pesticides usage, because more than 45% of annual food production is lost due to pest infestation. In particular, at tropical climates this is enhanced due to prevailing high temperature and humidity. However, the sporadic use has been leading to significant consequences not only to public health but also to food quality resulting in an impact load on the environment and hence the development of pest resistance (Giupponi and Rosato 1999; Luo and Zhang 2010). To sum up, the existing evidence arguments in favour of revising and restructuring the national agriculture policy and monitoring programs. As a first step, this chapter will discuss some elements of the Argentinean agricultural practices and policies, and then it will focus in reviewing pesticides? occurrence in the environment.
