Quantifying the Dynamics of Pesticides in Natural Waters

Abstract

A variety of trace analytical methods (solid-phase and liquid-liquid extraction, HPLC and GC-MS) for quantitatively assessing the input and behavior of pesticides and their metabolites (i.e., triazines, acetamides, phenoxy acids and organotin compounds) in natural waters and sediments are presented. The results of field studies illustrate the analytical methods performance such as simultaneous determination of compounds with different polarities, low detection limits, and high precision and accuracy.
