Pesticides determination in foods and natural waters using solid amalgam-based electrodes: Challenges and trends.

The intensive use of pesticides in agricultural practices has promoted the appearance of environmental and public health problems. So, there has been a sharp increase in the development of simple, fast, sensitive, selective, and low-cost methods to analyse pesticides. Among them, electroanalytical methods have been frequently employed; however, the performance of these methods is strongly influenced by the working electrode material and so an adequate choice is critical to success of the analysis.
