ABSTRACT

Die Sonne ist auch da wenn die Wolken schwarz und undurchdringlich

scheinen.

Ernst Jucker (1957)*

Toxicology has evolved as a multidisciplinary field of study and is still in rapid

evolutionary development. As such, toxicology overlaps many other basic

biomedical disciplines, including biochemistry, pharmacology, and physiology.

A recent event in this development has been the intersection of toxicology with

photobiology, opening the field of phototoxicology.
