eng	Rapid and sensitive voltammetric analysis of pesticides using silver solid amalgam electrode.	Within this work, the voltammetric behavior of herbicides triasulfuron, picloram and metamitron as well as of insecticides pymetrozine and imidacloprid has been studied on AgSAE with different surface modifications, and the voltammetric methods for its determination have been proposed. Differential pulse voltammetry in connection with AgSAE has been applied for development of sensitive methods of determination for investigated compounds and the relevant statistical parameters (e.g. LOD, LOQ or RSD) were calculated. All results obtained using AgSAE were compared with those achieved with classical hanging mercury drop electrode (HMDE), which could be replaced by the amalgam electrodes in the area of electroanalytical chemistry especially due to the toxicity of mercury. New proposed methods were successfully applied for analysis of practical samples of pesticide preparations and spiked river or dam water with good accuracy. It was proved that silver solid amalgam electrode represents an environmentally acceptable alternative to mercury electrodes in pesticides analyses.
