Mass Spectrometry in Ecotoxicology

Abstract

Risk assessment of chemical effects in the environment requires the understanding of the fate and behavior of anthropogenic chemicals in natural and technical systems, which is the focus of environmental chemistry. The exposure data obtained by environmental chemists are in turn used to evaluate the significance of toxicological effects in organisms, as studied by environmental toxicologists. Mass spectrometry-based techniques are frequently applied to monitor the exposure or investigate the effects of chemicals, particularly their mechanism of action. These techniques include, for example, targeted and non-targeted chemical analytics as well as diverse –omics methods. This chapter illustrates the application of mass spectrometry in environmental chemistry and toxicology using research projects carried out at our institute, with a particular focus on the aquatic environment.
