ABSTRACT
In recent years growing attention has been paid toward the discharge, presence and potential adverse effects of pharmaceuticals in the environment. Using different existing analytical methods several studies have already identified a variety of drugs in waste-, surface- and drinking water. The monitoring of surface waters for drugs is of great importance because drugs are designed to be biological very active substances. A capillary LC/ES-MS-MS method has been developed that enables the sensitive and specific detection of diazepam in water samples up to 0.1 ng/ml (LOD). It requires neither multiple extraction steps, nor the use of large volumes of organic solvent. Applying this assay we have detected diazepam in 'in/effluent samples' collected in Belgium and demonstrated the applicability for water analysis without off-line pre-concentration of the analyte.
