Determination of Routinely Monitored Herbicides in Drinking Water Samples Using Automated Solid Phase Extraction Prior to Liquid Chromatography/Tandem Mass Spectrometry

摘要

Most countries have regulations or monitoring programs to research and track the level of herbicide contaminants in drinking water. Many populations obtain drinking water from ground water supplies, and it is these supplies that are at potential contamination risk from leaching contaminants, such as herbicides. The US EPA has implemented an exposure research program aimed at conducting drinking water research on methods as part of the Microbiological and Chemical Exposure Assessment. This research is aimed at evaluating the chemical pollutants and their role and levels in which there is an unacceptable risk to either humans or wildlife, as well as evaluating the methodologies currently being used to determine levels of chemical pollutants.
