Analytical chemistry is an important tier of environmental protection and has been traditionally linked to compliance and/or exposure monitoring activities for environmental contaminants. The adoption of the risk management paradigm has led to special challenges for analytical chemistry applied to environmental risk analysis. Namely, methods developed for regulated contaminants may not be appropriate and/or applicable to risk management scenarios. This paper contains examples of analytical chemistry applied to risk management challenges broken down by the analytical approach and analyte for seom selected work in our laboratory. Specific techniques discussed are selective association complexation electrospray mass spectrometry (cESI/MS), gas chromatography/mass spectrometry (GC/MS), split-flow thin cell (SPLITT) fractionation, and matrix assisted laser desorption time of flight mass spectrometry (MALDI-ToF-MS). Specific analytes are haloacetic acids (HAA9), perchlorate, bomate, triazine degradation products, metal contaminated colloids, and Cryptosporidium parvum oocysts.
